The effects of the methanol subfraction from Pueraria Radix on hydrogen peroxide-induced lipid peroxidation and cadmium-induced cytotoxicity were investigated in NIH 3T3 fibroblast cells. After the methanol subfraction treatment, the content of MDA induced by 600 ${\mu}g$ $H_2O_2$ significantly decreased in proportion to the subfraction concentrations as well as 50 ${\mu}M$ $CdCl_2$-induced cytotoxicity. Especially, 200 ${\mu}g/mL$ concentration of methanol subfraction was strongly shown inhibition of lipid peroxidation and detoxification of cadmium. These results suggest that the methanol subfraction from Pueraria Radix retains a potential antioxidant and protective effect against cadmium.

This study was performed to certify the inhibitory effect of aqueous extracts from sixty-seven medicinal plants on the activity of xanthine oxidase in vitro. Among the sixty-seven medicinal plants, Scutellaria baicalensis Georgi, Citrus aurantium L., Polygonum multiflorum Thunb., Pueraria thunbergiana (Sieb. et Zucc.) Benth., Citrus unshiu Marcor., Rubus coreanus Miquel, Camellia sinensis L., and Poncirus trifoliata Raf. were regarded as effective anti-gout sources. The active substances of P. multiflorum root extract were very stable at pH 2.0 and high temperatures. Xanthine oxidase activity was proportionally inhibited when concentrations of P. multiflorum extract increased. The aqueous extract from P. multiflorum root at a concentration of 2.0 mg/0.1 mL inhibited xanthine oxidase by 73.8%.

Sasang-Medicine can classify all sympton with more simple classifying system than past Oriental-Medicine, because Sasang Byeon-Zeung(=classifying system of the sympton) separate by four clearly. The merit of this Sasang Byeon-Zeung can be seen more clearly on the part of the pathology of the expiratory-scattering and inspiratory-gathering of the Tae-Eum and Tae-Yang. On this view point, this thesis discussed the following subjects. 1. Investigate the theory of raising-falling and scattering-gathering developed in the Dongeui-Suse-Bowon. 2. Investigate the changes of the recognition of the Yang-Dog sympton and Jo-Yeol sympton argued as Interior-overheating-sympton of the Tae-Eum-In caused by liver's receiving heat. 3. Investigate the Yi-Je-Ma's view on the Eum-Yang in the argument of interior-overheating-sympton of the Tae-Eum-In caused by liver's receiving heat. As a result, the following conclusions were led to. 1. Dongeui-Suse-Bowon considers Spleen-Kidney has the couple motion of the raising Yang and falling Eum, and Liver-Lung has the couple motion of the expiratory-scattering and inspiratory-gathering. This theory of raising-falling and scattering-gathering is same as in the concept with the gathering. This theory of raising-falling and scattering-gathering is same as in the concept with the theory of raising-falling and floating-sinking of past Oriental-Medicine, but more consistently systematized in the pathology and prescription. 2. Dongeui-Suse-Bowon considers the Yang-Dog sympton and Jo-Yeol sympton as the interior-overheating-sympton of the Tae-Eum-In. As following the book, the fire of desire weeken the expiratory-scattering power of the lung, and deepen the shortage of the expiratory-scattering power comparison to the inspiratory-gathering power. Therfore the sympton can be treated by releasing ourselves from the desire and taking medicine strengthening the expiratory-scattering power. 3. In the early stage of the orintal medicine, they used prescriptions composed of So-Yang medicine and Tae-Eum medicine which can cool heat. Galgeun, Mawhang and Seungma were used in the age of Sanghanron, thereafter Jugoing's Jojung-Tang and Gongsin's Galgeunhaegi-Tang were developed as prescriptions of the interior-overheating-sympton of the Tae-Eum-In, and finally Tea-Uem-In Galgeunhaegi-Tang was settled by Yi-Je-Ma.

Compounds of isolated from roots extract of Pueraria thunbergiana were tested their inhibitory effects on $\alpha$-glucosidase and $\alpha$-amylase. Inhibitory activity of methylene chloride (MC) fraction and ethyl acetate (EA) fraction against $\alpha$-glucosidase showed more than 60% at a concentration of $500{\mu}g/m{\ell}$. Among the nine compounds tested on $\alpha$-glucosidase, biochanin A, (-)-tuberosin and calycosin from MC fraction and daidzein from EA fraction were stronger inhibitors than acarbose ($IC_{50}=530{\mu}g/m{\ell}$), and their $IC_{50}$ were 9, 144, 328 and $20{\mu}g/m{\ell}$, respectively. Biochanin A and (-)-tuberosin also inhibited $\alpha$-amylase activity as like as acarbose $IC_{50}=20.5{\mu}g/m{\ell}$), and their $IC_{50}$ were 22 and $348{\mu}g/m{\ell}$, respectively. Although daidzein was already known $\alpha$-glucosidase inhibitory effects, it was newly evaluated that biochanin A and (-)-tuberosin inhibited $\alpha$-glucosidase as well as $\alpha$-amylase, and that calycosin did $\alpha$-glucosidase.

In order to increase the antioxidant effect and preference of jujube-omija herbal sauce, we added ethanol extracts of 12 kinds of food and 12 kinds of medicinal herb to the sauce, and then evaluated the antioxidant activity and sensory characteristics. The antioxidant activity of the jujube-omija herbal sauces was greatly increased by the addition of ethanol extracts of foods such as green tea, mugwort, mint, lemon, leek, etc. and those of medicinal herbs such as ginseng. pine needle, the root of arrowroot, orange peel, etc.. Due to the high content of phenolic compounds, the ethanol extracts foods and medicinal herbs appeared to be responsible for high electron-donating ability and low hydroperoxide productivity. While the jujube-omija sauce with the extracts of green tea, mugwort, ginseng and pine needle were not preferred by the panels due to bitter taste and aroma, those of lemon, fruit of Chinese quince, orange peel, etc. were preferred with their sweet and a little sour taste and showed a high antioxidant activity. Especially, lemon juice was the best to increase the antioxidant activity and the preference of the jujube-omija herbal sauce.

Objective The objective of this study was to investigate the antioxidative effects of Puerariae Radix extract. Method Total antioxidant capacity (TAC), Total antioxidant response (TAR), Total phenolic content, Reactive oxygen species (ROS), 1,1-Diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activities, lipid peroxidation were examined. Result Total antioxidant status was examined by total antioxidant capacity(TAC) and total antioxidant response(TAR) against potent free radical reactions. TAC and TAR of Puerariae Radix extract at the concentration of 5 mg/ml were 2.02 and 1.50 mM Trolox equivalents, respectively. Total phenolic content of Puerariae Radix extract at the concentration of 5 mg/ml was 2.29 mM gallic acid equivalent. Concentration of Puerariae Radix extract at which DPPH radical scavenging activity was inhibited by 50% was 5.91 mg/ml as compared to 100% by pyrogallol solution as a reference. The inhibitory effect of the extract on lipid peroxidation was examined using rat liver mitochondria induced by FeSO4/ascorbic acid. Puerariae Radix extract at the concentration of 1 mg/ml slightly but significantly decreased TBARS concentration. The extract further prevented lipid peroxidation in a dose-dependent manner. The effect of Puerariae Radix extract on reactive oxygen species (ROS) generation was examined using cell-free system induced by hydrogen peroxide/FeSO4. Addition of 1 mg/ml of Puerariae Radix extract significantly reduced dichloroflurescein (DCF) fluorescence. The extract caused concentration-dependent attenuation of the increase in DCF fluorescence, indicating that the extract significantly prevented ROS generation in vitro. Thus antioxidant effects of Puerariae Radix extract seem to be due to, at least in part, the prevention from free radicals-induced oxidation, followed by inhibition of lipid peroxidation. Conclusion As a result, Puerariae Radix seems to have antioxitative effect and antioxidant compount.

Galgeun-tang (GGT) is a traditional medicinal formula that is widely prescribed to treat cold, asthma, and hives in Korea. Fermented herbal medicines can be made more effective than normal herbal medicines by increasing the absorption and bioavailability of the active compounds. In this study, we fermented Galgeun-tang to produce bioconversion constituents using Lactobacillus plantarum (GGT144), and found that four peaks were decreased, three peaks were increased and two new peaks appeared in the HPLC-DAD chromatogram. After HPLC-DAD-guided fractionation of the newly-appearing compounds (1 and 5) and the increased (6, 7, and 9) compounds, the structure of the compounds was determined using NMR and MS. Using this approach the compounds were identified to be pyrogallol (1), daidzein (5), liquiritigenin (6), cinnamyl alcohol (7), and formononetin (9), respectively. In addition, the decreased compounds were identified to be daidzin (2), liquiritin (3), ononin (4), and cinnam aldehyde (8) using HPLC-DAD analysis with standard compounds. The high performance liquid chromatography method was used to quantify the nine constituents in GGT and GGT144. All calibration curves of the standard compounds displayed excellent linearity with a $R^2$ > 0.9968.

This study was performed to investigate the effect of Puerariae radix-ethanol extracts rich in isoflavone on the antio-xidative system of rats. For this purpose, first, Puerariae radix was extracted with ethanol, and its total isoflavone and puerarin contents were analysed. Second, female Sprague Dawley rats were fed for 6 weeks with four diets which were based on AIN96G diet and supplemented with Puerariae radix-ethanol extracts to contain isoflavone. The isoflavone contents of four experimental diets were 0 mg, 500 mg, 1,000 mg, 2,000 mg per kg diet, respectively (control, P0.05%,P0.1%, P0.2%). Liver and erythrocyte activities of antioxidative enzyme such as superoxide dismutase (SOD), catalase,glutathione peroxidase (GSHpx) were measured. Also, plasma and liver malondialdehyde (MDA) concentrations, liver glutathione (GSH) and oxidized glutathione (GSSG) concentrations were measured. The total isoflavone content of Puerariae radix-ethanol extract was 3067.6 mg per 100 g extract and the content of puerarin was 2557.4 mg per 100 g extract. The erythrocyte activities of GSH-Px and catalase were higher in group P0.1% and P0.2%. But SOD activity of erythocyte did not show any difference by the Puerariae radix-ethanol extract supplementation in diet. The activity of SOD in liver increased significantly by the supplementation of extract, showing highest level in P0.1% group. The liver GSH concentration increased significantly in group of P0.05%, P0.1%, and P0.2% compared with control group (p <0.05). The GSSG concentration in liver showed no difference by the supplementation of Puerariae radix extract from the control group, except P0.2% group. The plasma MDA concentration did not show any significant differences by the extract supplementation. But the liver MDA concentration decreased by the extract supplementation, showing the lowest level in P0.1 % diet group. These results suggest that the supplementation of Puerariae radix-ethanol extract can inhibit lipid peroxidation in liver and enhance the antioxidative defense competence of rats.
