This study was carried out to investigate the extraction yield, the contents of total phenol substances and antioxidative substances, electron donating abilities, nitrite scavenging abilities of water and ethanol extracts from Cassia tora L. and Pueraria thunbergiana and antioxidative activity of water and ethoanol extract from Cassia tara L. Tatal phenol substances of water and ethanol extract from Cassia tora L. and Pueraria thunbergiana showed nearly the same levels, and the antioxidative substances of water and ethanol extract from Pueraria thunbergiana has as much as two times higher than those from Cassia tara L.. The nitrite scavenging abilities were measured at pH 1.2, 3.0, 4.2 and 6.0, respectively. Water and ethanol extracts from Cassia tora L showed 14.9%∼22.3% and 49.1%∼56.7%, and those from Pueraria thunbergiana revealed 57.7%∼61.0% of nitrite scavenging abilities, respectively. Especially the extracts from Pueraria thunbergiana showed higher pH dependence than those from Cassia tora L. The electrol donating abilities of water extract from Cassia tora L. were higher than those from Pueraria thunbergiana, and vice versa in the case of ethanol extracts. In the antioxidative activitiy of extracts from Cassia tora L. against linoleic acid during storage of 20 days at 50$^{circ}C$, peroxide values at the addition level of 5mg and 10mg were consoderably lower than 2mg although peroxide value increased above 375 after 12days of storage compared with the control(BHA-added) of 129 at 8days.

The antioxidative activity was observed in the ethyl acetate extract $(IC_{50},\;119{\pm}0.16\;{\mu}g/mL)$ from Pueraria thunbergiana. The DPPH radical scavenging effect of this extract was comparable with that of synthetic antioxdant, BHA $(IC_{50},\;88.39{\pm}1.1\;{\mu}g/mL){\times}\;10^{-3}\;{\mu}M$. Pueraria thunbergiana extracts against microorganisms were evaluated in terms of the minimum inhibitory concentrations (MIC). In general, C. albicans was stronger antimicrobial activity than the other microorganisms. in vitro the antitoxic activity of extracts of Pueraria thunbergiana on NIH 373 fibroblasts was evaluated by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide) method. Generally, detoxification effect by the extracts of Pueraria thunbergiana increased in proportion to the concentrations. When $10\;{\mu}g/mL$ of the hexane extract of Pueraria thunbergiana was treated it showed the highest antitoxic effects (p<0.01). These results suggest that the crude extract of P. thunbergiana has a potential therapeutic activity.

The diurnal changes of the stomatal conductance, transpiration and leaf water potential were measured in order to assess the water relations characteristics of Pueraria thunbergiana in August of 1995 and 1996. The results showed two different responses depending on the duration of rainless days. The microclimatic conditions were highly stressful on 2 August. Daily maximum temperature reached to $39.0{\circ}C$ and vapor pressure deficit was 3.55 KPa. During this time the leaf water potential decreased to -1.02 MPa and a marked reduction of stomatal conductance was shown. However, on 15 August the stomatal conductance increased with increment of photon flux density, and transpiration was highly maintained during the day time. Minimum leaf water potential was only -0.47 MPa in spite of high transpiration rate. Furthermore, on 15 August reduced leaf water potential during the day time was recovered rapidly with decrease of photon flux density, whereas recovery of leaf water potential on 2 August was delayed. However, reduced leaf water potential on 2 August was recovered untile the next dawn. Osmotic potential at turgor loss point of Pueraria thunbergiana on 2, 3 and 15 August was -1.79, -1.70 and -1.60 MPa, respectively. The vapor pressure deficit is more contributive to the regulation of stomatal conductance than leaf water potential.

Alpinia katsumadai is used in traditional oriental medicine as an antiemetic and for treatment of stomach disorders. This study was to investigate the effect of the 50% methanol extract of Alpinia katsumadai and Puerariae thunbergiana on ethanol metabolism in rat. The administration of 50% methanol extract of Alpinia katsumadai significantly decrease the ethanol concentration in rat. The AUC and Cmax of Alpinia katsumadai was 3.1 and 2.4 times less than the control group, respectively. It was more effective than Pueraria thunbergiana is known to as ethanol detoxicant. Furthermore, we tested on its ethanol metabolizing effect with the preparation containing this herb (Haeju pill) in beagle. The AUC of Haeju pill was about 1.9 times less than the control group. It was estimated that the extract of Alpinia katsumadai had feasibility as a ethanol detoxication agent.

In this experiment, the effects of Pueraria thunbergiana extracts on the activation of immune cells were studied. An immune cell-activating factor was partially purified from P. thunbergiana by means of physiological saline extraction, acetone precipitation, and heating inactivation. P. thunbergiana extracts increased the proliferation of spleen cells and induced the production of IL-2, IL-6, TNF-${\alpha}$, and IFN-${\gamma}$ by spleen cells. Also, they increased the proliferation of purified B cells and the production of IgM antibody in a dose-dependent fashion. The extract self-induced NO synthesis in a mouse macrophage cell line (RAW264.7). When cell lines were treated with extracts, the cytokines' (IL-$1{\beta}$, IL-6, and TNF-${\alpha}$) production was markedly increased. Therefore, P. thunbergiana extract can self-activate spleen cells, B cells, and macrophages. These results might be useful in further studies into a possible immune-activating agent derived from P. thunbergiana for the development of functional foods and drugs.

A mechanism of hair cell damage caused by noise and ototoxic agents is mediated through generation of free radicals and reactive oxygen species(ROS). It is known that most of animals have defense systems of ROS that protect against ROS, and the cochlea of animals also has ROS defense system, which appear efficient in detoxifying ROS generated under normal condition. This system includes several antioxidant enzymes such as superoxide dismutase(SOD), catalase(CAT), glutathione peroxidase (GPX), and glutathione reductase(GR). The radix of Pueraria thunbergiana(P. thunbergiana) is traditionally prescribed to attenuate the clinical manifestation of inner ear dysfunction and various clinical situations including fevers, gastrointestinal disorders, skin problems, migraine headaches, lowering cholesterol, and treating chronic alcoholism in Oriental Medicine. In the present study, to investigate the protection mechanism of ${\beta}-sitosterol$ from P. thunbergiana on cisplatin cytotoxicity toward HEI-OC1, we measured the effects of ${\beta}-sitosterol$ on activities of SOD, CAT, GPX, and GR in cisplatin treated cells. SOD, CAT, GPX, and GR activities were significantly increased in the presence of 0.001-0.1 ${\mu}g/ml$ of ${\beta}-sitosterol$ compared to the control group. These results indicate that ${\beta}-sitosterol$ protects cisplatin-induced HEI-OC1 cell damage through increasing the antioxidant enzyme system such as SOD, CAT, GPX, and GR.

The contents of isoflavones and 1,1-diphenyl-2-picryl hydrazyl (DPPH) free radical scavenging activities were determined in flowers (Puerariae Flos) and roots (Puerariae Radix) of Pueraria thunbergiana to differentiate both pharmacochemical or pharmacognostical usage of both oriental medicinal drugs. The tectorigenin contents in flower before and after acid hydrolysis were shown to be 17.10 ${\mu}mole\;g^{-1}$ and 49.58 ${\mu}mole\;g^{-1}$, respectively, analyzed by HPLC. However, the root displayed much less content of tectorigenin even after acid hydrolysis (6.56 ${\mu}mole\;g^{-1}$) than in the flower. Acid hydrolysis made glycitin and tectoridin of the isoflavone glycosides almost disappear in the flower and root. DPPH assay results demonstrated that acid hydrolysis of both extracts or both glycosides should increase free radical-scavenging activities due to the increase of isoflavone contents. It is also suggested that the flower had much higher concentration of isoflavonoids than in the root.

We previously reported the antimutagenicity, anti-lipid peroxidation and antiinflammtory properties of the three Chinese herb medicine, Kalopanax pictus, Pueraria thunbergiana and Rhus verniciflua, which have been used as therapeutics for diabetes mellitus and inflammation in Korea. Since these drugs have been used for the prescriptions consisted of several crude drugs, we investigated whether the extract of the three drugs could increase the individual drugs or not. The three extracts were independently prepared from K. pictus, P. thunbergiana, and R. verniciflua, which extracts were named the K-1, P-1 and R-1 in this order and the extract (KPR-1) was also prepared from the combined plant materials with each same weight of the three drugs.
