  • It is well known that lipidperoxide, formed in vivo, induced the denaturation of enzyme and destruction of cell membrane to acute injury of tissue. Aralia elata have physiological activates, the improvement of lipid metabolism, antidiabetic activity etc., which was thought to have the relationship to lipid peroxidation. The anti-lipidperoxidative effect of Aralia elata have not yet established. In this study, we examined the anti-lipidperoxidative effects of Aralia elata (Butanol fraction) on CCI$_{4}$ induced lipidperoxidation in rats, and elucidated the anti-lipidperoxidative mechanism. In rat liver homogenate intoxicated with CCI$_{4}$ (0.5 ml/100g), BuOH fraction of Aralia elata (80 mg/Kg/day) exhibited 85.41% anti-lipidperoxidative effect but in serum 69.63% inhibitory effects, respectively. In mitochondrial and microsomal fraction showed inhibition of 55.85% and 69.30%, respectively. In order to elucidate the mechanism of anti-lipidperoxidation effects of Aralia elata, enzymatic (NADPH dependent) and non-enzymatic (Ascorbic acid catalyzed) reaction, in vitro, were performed. In enzymatic reation, Aralia elata exhibited 59.43% anti-lipidperoxidation effects, but in non-enzymatic reaction exhibited 43.27% inhibition. Therefore, it is noteworthy that antioxidative power of them may mainly results from the inhibition by enzymatic reaction.

  • Cyperus rotundus L. (Cyperaceae) has been used as an analgesic and antiiflammatory agent and in the treatment of menstrual disorder in folk remedies. Cyperi Rhizomata, processed and unprocessed, were extracted with methanol and fractionated with petroleum ether, chloroform. Butanol, water. The effect of unprocessed Cyperi Rhizoma and processed Cyperi Rhizoma on $CCl_4$ induced lipid peroxidation and hepatotoxity have been tested in rats. BuOH. Water fractions of unprocessed Cyperi Rhizome enhanced the inhibition of antilipid peroxidative effects in liver lipid. In chemical parameters obtained from serum analysis. Butanol fraction of unprocessed Cyperi Rhizoma showed significant decrease in hepatotoxicity. In result, unprocessed Cyperi rhizoma has significant antilipid peroxidative effect and hepatoprotective activity.

  • To evaluate hepatoprotective effects of G009, an hepatoprotective agent which was extracted from the mycelia of Ganoderma lucidum IY009, we were, studied using $CCl_4$-and galactosamine-induced hepatotoxicity in rats. The ratio of liver weight to body weight, the value of glutamic oxaloacetic transaminase(GOT) and glutamic pyruvic transaminase (GPT) activities, the change of a lipids in serum, and the inhibitory activity of malondialdehyde (MDA) formation in serum and liver homogenate were determined in rats. G009 was not significantly changed of the ratio of liver weight to body weight and the content of lipids in serum, but reduced the serum GOT and GPT values in $CCl_4$-and galactosamine-induced hepatotoxicity in rat. Especially, protective effect of G009 on rat hepatic injuries induced by galactosamine was significantly appeared. $CCl_4$ increased markedly the formation of lipid peroxides in the liver homogenate, and serum. The increase of lipid peroxides by $CCl_4$-induced hepatotoxicity was markedly reduced by the treatment with G009. These results suggest that the hepatoprotective effects of G009 may be correlated with its anti-lipid peroxidative activity, therefore, it may be potential agent for hepatic disease.

  • 잔나비버섯 자실체로부터 열수추출하여 얻어진 고분자 및 저분자 분획의 이화학적 특성 및 생리활성 대하여 검토하였다. 고분자와 저분자 분획은 당과 단백질 및 소량의 hexosamine을 함유하고 있었다. 구성 당은 주로 glucose, galactose, mannose와 소량의 xylose, fructose, ribose 및 arabinose 등으로 구성되었으며, 아미노산의 경우는 당과 단백질의 결합력에 관여하고 있는 Ser과 Thr를 다량 함유하고 있는 것으로 조사되었다. 고분자 분획의 분자량은 10 kD 부근에서 주를 이루고 있는 것으로 나타났다. 항보체활성은 고분자 분획에서 높았으며, 항체생성능은 대조군에 비해 약간 증가하는 양상을 나타내었다. 탐식능, NO 및 $TNF-{\alpha}$ 생성능은 서로 상관성이 있는 것으로 조사되었다. 효소적 및 비효소적 지질과산화 유발에 대한 영향은 고분자 및 저분자 분획에서 모두 억제능을 나타내었다. 이와 같이 잔나비버섯 자실체로부터 추출한 고분자 및 저분자 분획은 면역활성 및 지질 과산화 억제효과 있는 것으로 조사되었다.
