Pueraria Radix has known to contain several ingredients of medical action. However, the bitter taste of Pueraria Radix has been an obstacle to develope the products and improve the added value of Pueraria Radix. To moderate the bitter taste of extracts from Pueraria Radix, charcoal powder was used successfully as an adsorbent. The component of the bitter taste from Pueraria Radix was hydrophobic, which mostly eluted with 40-60% ethanol and estimated to be acidic. Puerarin, the essential medical ingredient remained after the adsorption and seemed not be affected by the adsorption to charcoal powder.

In this study, we investigated the effects of green tea and Pueraria radix tea on the production of Apo B$_{100}$ in Hep G$_2$ liver cells and on the expression of the low density lipoprotein (LDL) receptor. Treatment with green tea resulted in a 60.7% decrease on the Apo B$_{100}$ concentration in Hep G$_2$ cells. Pueraria radix tea decreased Apo B$_{100}$ concentration by 63.5% in Hep G$_2$ cells. Green tea and Pueraria radix tea significantly decreased Apo B$_{100}$ concentration by 64.8% and 61.8%, respectively, in the media. Treatment of the cells with green tea and Pueraria radix tea also significantly decreased the intracellular total cholesterol, but total cholesterol concentrations in the media increased by 26.4% (green tea) and 23.6% (Pueraria radix tea) above that measured in the media of control cells. The addition of green tea and Pueraria radix to the media of the Hep Gz cells increased the LDL receptor binding activities by 84.1% and 79.4%, respectively.

This study was carried out to evaluate the ostrogenic/antiandrogenic activity of Puerariae Radix in Sprague-Dawley rats. It has known that diverse phytoestrogen were included in some Puerariae Radix, especially in Pueraria mirifica. The Uterotrophic assay and Hershberger assay were performed to evaluate the ostogenic/antiandrogenic activity of various Puerariae Radix (Pueraria thunbergiana, Pueraria mirifica and Butea superba). In Uterotrophic assay, the extracts of Puerariae Radix were administered subcutaneously to immature female SD rats from 19 to 21 days of age. The wet uterus and vaginal weighs significantly increased in the group only treated with extracts of Pueraria mirifica. But, in Hersh-berger assay, all extracts of Puerariae Radix did not show any effects in the castrated rats. These results suggest that Pueraria mirifica has not undrogenic/antiandrogenic effect but potent estrogenic effect. It is possible that components of Pueraria mirifica may act as endocrine disruptor in human body.

시판 갈근으로부터 Isoflavanoid 성분인 Daidzein과 Daidzin을 분리 정제하고 이를 표준물질로 하여 시판 칡차 8종에 대한 칡성분 분석을 HPLC 방법으로 시도하여 다음과 같은 결론은 얻었다. 1. 칡차의 성분 분석법은 종래의 TLC법에 비하여 HPLC를 이용, 신속하고 정확하게 분석할 수 있었다. 2. 추출방법에 따라 성분함량이 크게 영향을 받아 Daidzein을 분석할 경우는 냉침법이, Daidzin의 분석시는 가열 추출법이 양호하였다. 3. 한국산 갈근중 Daidzein과 Daidzin은 0.08% 및 0.66% 함유되었다. 4. 시판 칡차중 고형차류는 칡의 성분이 표기량에 비하여 매우 적게 함유되거나 전혀 함유되지 않은 예도 있으며 액상차의 경우는 엑기스 고형분이 4∼5%가 함유되었다.

In order to fine antioxidant and whitening agent source from nature, the comparisons of antioxidative activity and tyrosinase inhibitory activity were carried out for various ethanol extract on Pueraria Radix, Poria Cocos, and Coptidis Rhizoma. Comparing for three ethanol extracts, the highest electron donating ability was found at Poria Cocos (81.2%), but, the highest SOD-like ability, at the Coptidis Rhizoma(58%). Xanthine oxidase experiment exhibited 23.3% of hindrance effect in Pueraria Radix, and 79.3% in Poria Cocos. To evaluate at the whitening effect, tyrosinase inhibitory activity was conducted. Tyrosinase inhibitory activity was detected at 17.9% in the Puerariae Radix, 5.2% in the Poria Cocos and 83.3% in the Coptidis Rhizoma. From these results, we suggest that the ethanol extracts from Pueraria Radix, Poria Cocos, and Coptidis Rhizoma can be used for cosmetic ingredients.

다양한 생리활성을 갖는 것으로 알려진 갈근을 중급 정도의 녹차와 혼합하여 갈근녹차를 제조하고 기호도와 관련이 있는 휘발성성분을 동시증류추출법에 의해 추출하여 GC 및 GC-MS로 분석, 동정하고 비교하였다. 갈근과 녹차를 1:1로 혼합한 갈근녹차의 향기성분으로 총 82종류를 동정하였다. 갈근녹차에는 갈근의 향기성분 18종류와 녹차의 향기성분 33종류 및 공통으로 포함된 31종류의 화합물들로 구성되어 있었다. 녹차의 향기성분으로 linalool, $\alpha$-ionone 및 nerolidol 등의 꽃향과 safranal, methyl butanal 등의 달콤한 향이 대부분을 차지하였다. 갈근의 향기성분으로 hexanal, trans-2-nonenal 및 $\beta$-selinene 등의 풋풋한 향과 decanal, limonene 등의 달콤한 향이 대부분을 차지하였다. 갈근녹차의 향기성분은 녹차의 향기성분인 달콤한 향을 띄는 furan류와 꽃향이나 산뜻한 과일 향을 띄는 linalool, nerolidol, 구수한 향을 띄는 pyrazine류와 pyrrole류에 갈근특유의 향기성분인 terpene계 화합물과 풋풋한 향을 띄는 trans-2-nonenal 및 $\beta$-selinene 등이 혼합되어 나타났다.

Objectives Ethanol is a potent inhibitor of muscle protein synthesis. Muscle mass is regulated by the balance between rates of protein synthesis and protein breakdown. Both acute and chronic alcohol consumption inhibits synthesis to a greater extent than degradation. Protein synthesis is more intensely decreased in type II fibers than in type I fibers. Apoptosis has been shown to occur frequently in a variety of tissues in response to chronic alcohol feeding. Increased muscle fiber apoptosis has been shown in alcoholics with myopathy. Pueraria radix has been used for many disorders such as fevers, gastrointestinal disorders, muscle aches, allergies, respiratory problems, skin problems, high blood pressure, migraine headaches, lowering cholesterol and treating chronic alcoholism. We therefore tested the hypothesis that oral treatment with Pueraria radix could reduce the ethanol-induced muscle atrophy. Methods Young male Sprague-Dawley rats were orally given 25% ethanol (5 ml/kg, body weight) daily with Ethanol for 4 weeks. Normal group was similarly administrated with saline. The Rats of Pueraria radix treated group (EtOH+PR) were orally administrated Pueraria radix water extract, and rats of EtOH group were given with the vehicle only. After 4 week, the morphology of gastrocnemius and plantaris muscles were assessed by hematoxylin and eosin staining. The immunoreactivities of pre-apoptotic BAX and anti-apoptotic Bcl-2 proteins were also measured. Results The muscles from rats of EtOH group represented a significant reduction in average cross section area compared to Normal group. EtOH+PR group had increased fiber compared to the EtOH group. Moreover, to investigate the ethanol-induced muscular apoptosis, the immunohistochemical analysis of Bax and Bcl-2 was carried out. The treatment with Pueraria radix (EtOH+PR) significantly decreased BAX expression and increased Bcl-2 expression 4 weeks after ethanol administration when compared with Normal group. Conclusions These results suggest that Pueraria radix water extract has protective effects on chronic alcohol induced myopathy.

This study was designed to investigate the effect of Pueraria radix extract on lipid metabolism in the rats fed high fat diet. Male sprague dawley rats were given 5% Pueraria radix extract and fed diet containing 20 weight % fat. The results obtained were summarized as follows. Serum ALT and AST activities were reduced by Pueraria radix extract. Levels of total lipid, total cholesterol and triglyceride in the serum were higher in the HF group than in the control, but showed no significant differences between control and HF Pue group. Liver total lipid, total cholesterol and triglyceride contents were increased by high fat diet, but were lower in the HF Pue group than in the HF group. Fat absorption rate was increased with high fat diet feeding and higher in the HF Pue group than in the HF group.

This study was designed to investigate the effects of Korean Pueraria radix extract in Pb administered rats. Pb exposed rats were given 1% Pb in the diet. $\delta$-Adminolevulinic acid(DALA) and urinary glucose levels were increased with Pb administration and were lower in the Pb group than in the group administered Pb alone. Hematocrit value was decreased with Pb administration and was higher in the Pb group than in the C-Pb grou. $\delta$-Aminolevulinic acid dehydratase (DALAD) activity was decreased in the Pb group. ALT and AST were increased by Pb added and were lower in the Pb group than in the C-Pb group. Serum Pb content was higher in the Pb exposed rats than in the control groups, and no significant difference was found due to extract of Pueraria radix supplementation. Levels of liver, kidney and femur lead were reduced by Pueraria radix. Lead contents in feces and urine were higher in the Pb added groups than in the control group, and level of feces lead was increased by extract of Pueraria radix.
