Team Information
Mr. Ye, founder of Yerherb Inc., was born the rural areas of Guangdong, China.
At the age of 18, he started his career working at various traditional herb shops in
different large cities. Intelligent, hard working, honest, Mr. Ye was promoted to main
buyer position over the years. Due to the wars in Mainland China, Mr. Ye and his wife
fled to Hong Kong, subsequently raising a family of eight children there. By the time
Mr. Ye decided to immigrate to the United States, he had become a shareholder of the
herb chain he worked at.
When Mr. Ye moved to Los Angeles in 1979, he immediately saw the vast
business opportunity due to the lack of availability of traditional Chinese herb in
United State. Yerherb officially opened its first storefront as a small family operation.
Its reputation grew rapidly in the US, the herb products sells many places in US.
Jingyi Guan and Xin Wang was entered in this company in 2005, they were in a
project group developing the Ganederma lucidum herbal tea product that will be talk
in details below.
Product Summary
The product produced is a Ganoderma lucidum extract herbal tea, with multi-
functions on people health. It has higher concentration of active ingredient and the
cost of the product is lower than the Ganoderma lucidum products present in the
market now.
Ganoderma lucidum
Ganoderma lucidum or Lingzhi mushroom, which has a shape of semi-circle or
kidney-like, is a sort of medical mushroom and has been used as popular remedy in
traditional Chinese medicine for more than 2,000 years. In most of Chinese ancient
medical works, we can see the similar description about G.lucidum-------a super
panacea. It is effective for treatment or prevention of neurasthenia, high blood
pressure, arrhythmia and enhancement of resistance of various diseases. What is
5
more, from recent study, G.lucidum still has efficacy of curing cancer, diabetes and
even inhibiting senility. Nowadays the mushroom has been listed in the American
Herbal Pharmacopoeia and Therapeutic Compendium.
Triterpenes
Based on the previous study about the active ingredients in G.lucidum, the
efficacy mentioned to a great extent relates to chemical “triterpenes”. Triterpenes is a
series of secondary metabolites which belong to lanostane when the mushroom
forming fruiting body. At least 170 different triterpenes have been exacted from
G.lucidum so far. Here is a image of the structures of three typical triterpenes (or
ganoderic acid).
6
Triterpenes can inhibit secretion of histamine from mast cells which can cause
allergy and inflammation. What is more, ganoderol A, ganoderol B, ganoderic acid Y
which belongs to triterpenes can robustly inhibit cholesterol synthesis by interrupting
the synthetic pathway from acetate to cholesterol. Fe2+—ascorbic acid which can
cause peroxide of lipid and 1,2,3-Benzenetriol which cause oxidation of erythrocyte
membrane can also be inhibited by triterpenes. In recent study, triterpenes has been
known that has effect in suppressing the growth and proliferation of cancer cells and
inducing apoptosis in a variety of leukemia, lymphoma, and myeloma cells by
increasing the amount of T lymphocyte and enhancing the activity of NK cells, IL-2,
tumor necrosis factors and macrophages.
However, the content of triterpenes is very low in wild-type G.lucidum, which
results in high cost in pharmaceutical industry.
Mevalonate Pyrophosphate Decarboxylase (MVD)
7
Triterpenes is synthesized through the MVA (mevalonate) pathway. (Figure) And
during the pathway, a lot of enzymes,including HMGR,FPS, SQS and MVD, show
essential functions. Among these enzymes, MVD (mevalonate pyrophosphate
decarboxylase) is a key enzyme in catalyzing mevalonate-5PP into isopentenyl-PP
within the process of synthesis of Triterpenes.

amplifying the gene has been known nowadays.(figure)
Agrobacterium-Mediated Transformation System for Fungi
Tumor inducing plasmid (Ti) is a kind of vector that originally used in
Agrobacterium-mediated transformation to plants. Target gene could be inserted into a
region called ”T-DNA” on the Ti plasmid which would be integrated into genome of
the Agrobacterium-infected plant cells by recombination. Now of Agrobacterium-
mediated transformation system for fungi has been well-established and shows a very

good transforming efficiency by modifying the T-DNA sequence to make it include
homologous region with fungi. Additionally, specific selection markers and promoters
to fungi are utilized in such a system.
Gpd Promoter
Strong promoters are the sequences that have high affinity with RNA polymesare
and can promote synthesis of mRNA highly efficiently. gpd (glyceraldehyde 3-
phosphate dehydrogenase,GAPDH) promoter is a strong promoter in large

filamentous fungi which can be used for constructing the over-expression vectors. The
sequence of the promoter has been known by cloning the 5’ flanking region of the gpd
gene.

Research and Development
Cloning flow chart:
Hyphae Collection
Before all the experiments we would conduct, tissues of the fungi in specific
stage which would produce mRNA we wanted should be obtained. The wild type
strain G20 will be cultured in the PDA liquid medium, which with 150rmp shaking
bed incubation for 7 days under 28 . Then the hyohae could be collected by gauze. ℃
Obtaining Target Gene mvd
To obtain the target gene mvd, isolation of total RNA for synthesis of cDNA
should be accomplished first. Our team used liquid nitrogen to grind hyohae. After
homogenization, chloroform and isopropanol were used for isolation of RNA. The
isolated RNA was purified by Dnase and phenol. The quality of the total RNA was
proved good based on the result of gel electrophoresis.
The total RNA we acquired were then utilized in synthesis of cDNA by reverse-
transcription. For the reason that fungi is eukaryote which has poly(A) tail at 3’end of
13
mRNA, Oligo(dT) and reverse-transtripatase (M-MLVRTase) were used respectively
as primer and DNA polymerase during the reaction.
The cDNA products we obtained is a mixture of cDNA from different mRNA. To
get specific cloning product of mvd gene, we designed a pair of primer(named MVD-
O1 and MVD-O2) based on the cDNA sequence from GenBank (No.HQ596495.1).
Furthermore, we introduce two restriction sites respectively into these two primers
(sequences with underlines):
MVD-O1: 5’- ACTGggatccATGAGCGTATACCAAG-3’ (Bam HI)
MVD-O2: 5’-ACTGtctagaTCACTTCGGAAGGCC-3’ (Xba I)
Then we conducted PCR for specific amplification of mvd gene using the MVD-
O1 and MVD-O2 primers and total cDNA and successfully obtained target gene mvd.
Construction of Over-Expression Vector GL-GPE
Before construction of the over expression vector GL-GPE, strong promoter gpd
is needed to be purified from total DNA and specifically amplification. Based on the
sequence of gpd we got from other lab, we designed the specific primers GL-GPD-F1
and GL-GPD-R1 and introduce BstX1 site and Aat II site respectively into the
flanking region of the primers.The regions with underlines are BstX1 site and Aat II
site.

GL-GPD-R1:5’-GATCccaacatggtggAGGGGGATGAAGAGTGAG-3’ (BstX I)
After we obtained the specific amplified products, we created recombinant
plasmid PGL-GPD with plasmid pCAMBIA 1300.

Diagram of pCAMBIA 1300 plasmid
pCAMBIA 1300 plasmid is a Agrobacterium binary vector for plant or fungi
transformation. This plasmid is a shuttle vector which can be replicated and expressed
in both E.coli and Agrobacterium. It has two selective markers, one is hgyR
(hygromycin resistance) which is used for plant or fungi cells selection and the other
marker is KanR (kanamycin resistance) which is used for bacteria cells selection. We
digested the pCAMBIA 1300 plasmids and gdp promoter fragments with BstX1 and
Aat II. Then we used T4 ligase to ligate the pCAMBIA 1300 plasmid vector and the
gpd fragments. And we got ligation product pGL-GPD.
17
Construction of binary vector pGL-GPD
Aat II
Competent E.coli Cells were created by heat shock with Ca2+ and mixed with
ligation product we got from last step. Then we incubated the solution and plated the
solution onto kanamycin LB medium for selection of transformant colonies. After
incubation, we took individual colonies on the plates, purified plasmid from cells
using kit and did RFLP (restriction fragment length polymorphism) for screening.
Within the screening, we extracted the plasimds from transformant cells. After
digestion by BstX I and Aat II, we did agrose gel electrophoresis with EtBr and
identified the recombinant colonies which can show a band of inserted fragment. Then
we cultured cells from those colonies and isolated vectors pGL-GPD. Here is the gel
electrophoresis result.
The inserted gpd promoter replaced the CAmv35S promoter which was used for
expression of higher plant genes. But the plasmid still needed another gpd promoter
with different direction for following inserted target gene expression. For that, we
designed two primers for specifically amplification gpd promoter fragments with two
different restriction sites (which were located in MCS):
GL-GPD-F2: 5’-GATCggtaccTCCAAAGCCGCTCTCATGG-3’ (KpnI)
GL-GPD-R2: 5’-GATCgaattcAGGGGGATGAAGAGTGAG-3’ (EcoR I)

Same method of digestion and ligation of inserted fragments and plasmids were
used here as above with enzymes KpnI and EcoR I.
After transformation and selection for transfromants, we did PCR screening and
agrose gel electrophoresis using GL-GPD-F2 and GL-GPD-R2 primers for obtaining
the recombinant starins. Then we cultured the strains and isolated over-expression
vector named GL-GPE.

Obtaining Agrobacterium Strains Containing Ti Plasmid GL-MVD
In construction of mvd over-expression plsamid GL-MVD, GL-GPE vector and
mvd cDNA fragment was digested with Bam HI and Xba I and ligated with each other
by T4 ligase.
20
Construction of over-expression vector GL-GPE
After using heat-shock with CaCl2 to make competent agrobacterium, GL-GPE
solution were mixed with the cells. Because the Plasmid has a kanamycin resistance
selection marker, we used LB medium with kanamycin to select transformants.

Construction of over-expression vector GL-MVD
Then we took transformant colonies and isolated plasmid which was used for
RFLP (restriction fragment length polymorphism) screening. During the process of
RFLP, we digested the plasmids with BamH I and Xba I and conducted the agrose gel
electrophoresis. The recombinant colonies were identified when the band of inserted
mvd gene (1203bp) shown on the gel.

Agrobacterium Tumefaciens-Mediated Transformation
Before transformation of the GL-MVD plasmid into G20 Ganoderma lucidum
strain, protoplasts of the fungi were prepared. The grinded hyohae was treated with
lywallzyme to remove cell wall. Then the solution of Agrobacterium was mixed with
the protoplasts and incubated for infection. The mixture then was plated on
hygromycin PDA medium to select transformants.
And then these tranformants were subjected to chromosome DNA extraction for
PCR screening with gpd promoter primers GL-GPD-R2 and mvd primer MVD-O2 to
test if the fragment has been inserted into chromosome genome and if the gpd
promoter has fused with gene mvd. After obtaining amplification products, we did
agrose gel electrophoresis to identify recombinants which shown the band of inserted
mvd gene. And we named those recombinant strains “GMOEi”(i=1, 2. 3.......15)

Triterpenes Over-Expression Strains
After culturing such recombinant strain for 20 days, we tested and compared the
triterpenes contents of the over-expression strains with wile-type. In this experiment,
we used ultrasonic method to bread the cells and extract triterpenes by chloroform.
Then we used the vanillin perchloric acid colorimetric method to measure oleanic acid
content for establishing standard curve in standard solution and triterpenes content in
the strains by testing OD values under A245nm. At last, we found that triterpenes
content of one of the over-expression strains GMOE10 which was 3.5mg/100mg dry
weight was 101% more than the content of wild-type (G20).

Passage Stability
To ensure the passage stability of the insertion, we did subculture of the
GMOE10 strain respectively for 3/5/10 generations and test the triterpenes content.
The results of subculture show that triterpenes over-expression phenotype of the
GMOE10 was stable from generation to generation.

Optimal Time Length of Planting
Though we obtained the over-expression strain, it was still not enough for
optimize triterpenes producing for the reason that the secretion of triterpenes are
different at different stages of life cycle of Ganoderma lucidum. So we designed an
experiment to find out the optimal time length of planting. Here we adopted the well-
developed planting method as in agricultural industry to culture the GMOE10 strain.
sawdust, bran, sucrose, gypsum, water will be mixed following a ratio equal to
73:25:1:1:65 and filled into LDPE bag as compost. The compost were then sterile and
adjusted to pH 8.0. After planting the 20-day GMOE10 mycelium in different bags,
we marked those bags with “15 days”, “35 days”, “55 days”, “75 days”, “90 days”
which meant different time length of growing for different bags. These mycelium
contained bags were incubated under 27 and 90% air humidity. (image)After℃
finishing incubation, we extracted triterpenes using ultrasonic and chloroform and
measured the contents of triterpenes of different samples. The result indicated that
optimal time length of planting was 75 days.

Scale-up ProductionPlanting
To obtain enough Ganoderma lucidum as raw material, we built up green houses
for large-scale planting. Same method including 75-days culturing as what we
mentioned above was used for planting. Additionally, beside temperature and air
humidity, light was another factor needed attention. Too strong or too weak light
would inhibit the growth of the fruiting body of the fungi.
26
Supercritical CO2 Fluid Extraction
To further enhance the efficiency and safety and lower the cost and
environmental contamination of triterpenes extration in Industrial production, we
decided to adopt the supercritical CO2 fluid extraction( SFE) method. Such a
method is based on the principle that when the supercritical CO2 fluid gets in touch
with and dislsoves the mixture, compositions which have different polarities, boiling
points and molecular weights could be separated under different pressures and
temperatures. Then when the fluid returns to CO2 gas, the extract could be
precipitated. Because the method works under a temperature range from 35 to℃
27
Planting G.lucidum
40 , the volatile compositions could effectively maintain after extraction. We℃
purchased a 40L SFE equipment which combined with ultrasonic breaking from
Taiwan Supercritical Technology CO., LTD, and such mixed extraction method
provided a dramatically enhancement in efficiency of extraction from 3.5% to 41%.
Electuary Product
To produce electuary for G.Lucidum tea, the extract was evenly mixed with
dextrin with a ratio of 1:20 to make extractum. After squeezing trough the screen
mesh (mesh number=20) to make powders, 70 heat was used to dry the powders℃
and finished products were packaged. And we also produced canned drinks from dry
powdered.

Efficacy Testing
Ganoderma lucidum extract on mice test approved by FDA
The effects of Ganoderma lucidum extracts on the immune function and
growth of mice under the experimental incubation were studied. The results
showed that the weight of mice gained in the testing groups were higher than the
control groups after they fed on the extracts, and their abdomen phagocytic index
and phagocytosis rate of macrophages increased significantly after they fed on the
extracts for 30 days and did injections for 7 days. The rates between the mice 's
liver and spleen weights to their body weights increased compared with the
negative control. The results suggested that Ganoderma lucidum extracts
enhanced the mice 's immune function.
The material and protocol for the test approved by FDA:
Preparation of the chicken blood with red blood cells
Extract 1ml chicken blood from the live healthy chicken wing. Transfer the
chicken blood into 5ml Alsvers solution. Made a 5% of the cells suspension with
sterilized saline.
Preparation of Ganoderma lucidum extract water used in our product
Method used was same as our product extraction as previously discussed.
Testing on different groups of mice
The animals used in this experiment are pure white mice, weight 16g-18g.
These mice were divided into 6 groups at random, each group of 10, with free
feeding standard feed. Group 1 ~ 4 group drank Ganoderma lucidum extract
31
water, the concentration respectively 3. 2 mg/mL, 11. 2 mg/mL, 32. 0 mg/mL and
140 mg/mL, in feeding after 30 days, testing groups of mice did celiac injection
with the different concentrations of Ganoderma lucidum extract of 1 mL/day for
7 days. Group 5 was negative control group, which drank distilled water. 30 days
after, they were injected of saline by 1 mL/day for 7 days. The group 6 as the
positive control group, which had the same breeding method as the negative
control group. Before two days of the death of the mice, the abdominal cavity
injection was performed on them with cyclophosphamide (final concentration of
0. 75 mg/m, L), 1 mL/day, continuous (2 days). In 24 hours after the last
injection, they were executed by cervical dislocation method. Recorded each feed
quantity and water quantity, and weighted each mouse in different groups,
calculated the mean of each group.
Mice abdominal cavity macrophage specimen preparation
Mice treated by intraperitoneal injection of 5% chicken blood red blood cells,
each mouse injected by 0.5ml. The cervical dislocation method executed after 2
hours of injection. Instantly by intraperitoneal injection of 0. 5 mL saline, gently
rubbed the abdominal cavity for 1 min, cut open abdominal skin, and made a
small cut in muscle layer, transferred peritoneal fluid on the clean slide, incubated
for 30 min at 37℃. Using 10% Giemsa staining before observe under the
microscope. Direct observed under microscope, there were 2000 macrophage in
each mouse. The phagocytosis rate and phagocytic index were being calculated:
Phagocytosis Percent = (phagocytose chicken blood red blood cell number of
macrophages present 2000) x 100%
Phagocytic index = total number of chicken blood red blood cells being
phagocytized ÷ number of macrophages present phagocytose chicken blood red
blood cells
Determine the ratio of the organ weight to weight of the mice
After executed of the mice immediately, opened the abdomen and chest,
32
quickly removed the liver, lung, spleen, thymus, they were weighing respectively.
Calculated organ to body weight ratio and the average value of 10 mice in each
group.
Result and Discussion:
Effect on mice abdominal cavity macrophage phagocytosis
Microscopy results show in table1, four different concentrations of Ganoderma
lucidum in experimental mice abdominal cavity macrophage phagocytosis rates
compared with negative control group have obvious improvement, increased in 20.
16% ~ 69. 79%, and got a significant or extremely significant difference. The
concentration with 3. 20 mg/mL Ganoderma lucidum group phagocytosis rate
increased the most, the rest of the groups phagocytosis rate increased slightly. Positive
control group was lower than negative group by 42. 99%. This shows that Ganoderma
lucidum extract water had enhanced the experimental mice abdominal cavity
macrophage for chicken blood red blood cells phagocytosis rate, improved the cellular
immune function of mice.

From the data shows in table 2, by feeding with Ganoderma lucidum extract water,
the mice growing average weight is greater than the control group, different
33
concentration of Ganoderma lucidum group had different weight gain. The
concentration with 3.2 mg/ml increased the most. The highest concentration of
treatment group, weight gain was not the most. The reason might be that with the
increase of Ganoderma lucidum component content in extract solution create the
bitter taste of the drinking water, make high concentration group water consumption
lower than the control group and low concentration group, which affect weight gain.

As shows in table 3, mice in different concentrations of Ganoderma lucidum groups
by drinking Ganoderma lucidum extract water after 30 days and 7 days of injection,
the liver, spleen and thymus to body weight ratios were significantly increased than
the control group, and had no obvious adverse effect on the lungs. Spleen and thymus
are immune organs, the liver has detoxification function. From this result, the long-
term use of a certain amount of Ganoderma lucidum extract solution can improve the
body's detoxification ability. In this experiment, the development of immune organs in
mice had promoted effectively, it had the effect that increased in the body's immune
function.

Safety Testing
There are two types of safety tests were performed. They are ELISA and PCR tests.
The FDA required manufactures to to label their products with regards to eight
specific allergens: milk, eggs, fish, shellfish, peanuts, wheat, soybeans and tree nuts
since 2005. These allergens are responsible for over 90% of the documented food
allergen-related cases. The most common and preferred methods approved by FDA
for allergens testing in food industry are ELISA and PCR.
The testing methods have been developed that can now detect allergens in finished
products even at very low concentration as per million (ppm) range. By performing
this test, our product can be detected if it contains any popular allergen at the
molecular level. The allergens then can be avoiding during manufacturing or being
labelled on the product box for alert.
ELISA methods detect the actual allergen protein molecule by binding antibodies to
the allergen and then using an enzyme-linked conjugate to create a colorimetric
change that can be measured.
The PCR methods, which are more sensitive and detect the DNA molecules of
35
these allergens, can be used in raw and finished products and are not affected by the
heating process, because DNA typically remains intact after being exposed to the high
temperatures most foods. As food allergens are becoming an increasingly important
issue in food safety. These two tests are crucial before the food products hit the
market. Form the results of ELISA and PCR test. There was not any popular allergen
ingredient being detected in our product.

Ganoderma lucidum has been used in China for long time, there are several
beneficial effects of Ganoderma lucidum have been claimed. The majority of these
claims have not been studied in controlled clinical trials, but there has been an
abundance of clinical use, as well as in vitro and animal testing data support its safety.
The safety of using it is further supported by common use of Ganoderma lucidum as
an edible mushroom and broad exposure to consumers with no adverse effects
reported.
Mammalian Toxicity Testing
In 2012, a double-blind, placebo-controlled, parallel group interventional trial was
performed by using our product. There were 50 generally healthy volunteers (age 18-
65 years, BMI 19-35) were administered beverages containing placebo (control) and
our herbal tea includes Ganoderma lucidum active ingredient (1.5g/day) for 12 weeks.
After drinking for 12 weeks, there was no adverse effect on both groups. The group
36
consumed the active ingredient reported they got better sleep, and felt the herbal tea

Consumer Perception of the Product
The existing herbal teas in the market are approximately 6 to 7 dollars per box.
They could be our major competitors. As most of the herbal tea in the market now
only has one or few functions or just with some herbal or fruit flavors, they
cannot be considered as functional herbal tea. Our product includes very precious
ingredient. Which has the same value as ginseng, cubilose. By doing market
research, most of ginseng tea in market in US are imported. It is difficult to get
them in America’s popular supermarkets. Our product is planted in the US and
compared to other precious herbal product it has higher active ingredient. It is the
best choice for the people to consume with long time to maintain their health and
