The antilipidperoxidative and hepatopreventive effects of Aloe water extract (30 mg, 50 mg, 100 mg) were investigated at the levels of liver-total homogenates and the sera of SDrats intoxicated with CCl4 (0.5 cc/100g) and 50% ethanol. We measured MDA (Malondialdehyde) in the liver homogenate, AST (L-Aspartate-2-oxoglutarate aminotransferase) and ALT(L-Alanine-2-oxo-glutraate aminotransferase) in the serum. The analysis of the measurement indicated that Aloe water extract reduced MDA, ALT and AST significantly and their reduction was in relation to dose dependence. In rat liver homogenate intoxicated with ethanol and CCl4, Aloe treatment group markedly inhibited lipidperoxidation by 30%∼70%. In rat serum intoxicated with ethanol and CCl4, Aloe treatment group inhibited AST, ALT by 40%∼90%. In these data Aloe may be used to inhibit or prevent the hapatic toxicity with results from the environmental and alcohlic factors through the further study of its exact antihepatotoxic mechanism.

Houttuynia cordata (Saururaceae) has pungent smell and taste. It has been regarded as detoxicant, antipyretic, antiinflammantory and diuretic agents. In order to evaluate antioxidative and antilipidperoxidative efficacies, its fractions ($H_2O$, 20% MeOH, 40% MeOH, 60% MeOH, 170% MeOH) were measured by DPPH method and TBARS assay on rat liver homogenate. It was revealed that 60% MeOH fractions had potential antioxidative activity and inhibited lipid peroxidation significantly: In active fractions, we isolated rutin, hyperin, quercitrin and quercetin.

The root of Polygonum cuspidatum (Polygonaceae) has been used as treatments of hyperlipidemia, dermatitis, gonorrhea, favus athlete's foot, inflammation in traditional medicine. In order to examine anti-lipidperoxidation activity, hexane, EtOAc, BuOH and water fractions of its methanol extract were administered to carbon tetrachloride intoxicated rats. Ethylacetate fraction exhibited antilipidperoxidative effect on liver lipid homogenate and the radical scavenging effect on DPPH. Serum transaminase, AlP, triglyceride and total cholesterol contents significantly decreased by administrations of ethylacetate fraction.

The antilipidperoxidative and hepatopreventive effects of Houttuynia cordata extract(HCE) were investigated at the level of liver homogenates and serum of SD rats intoxicated EtOH(3g/kg for 3days). We measured MDA(malondialdehyde) in the live. homogenate, AST(1-aspartate-2-oxoglutarate aminotransferase) and ALT( 1-alanine-2-oxoglutarate aminotransferse) in the serum. The analysis of the measurement indicated that HCE reduced MDA, ALT and AST significantly and their reduction was in relation to dose dependence. In rat liver homogenate intoxicated with EtOH, HCE treatment group inhibited lipidperoxidation by 50-75%. In rat serum intoxicated EtOH, HCE inhibited AST and ALT by 40-70%.

A great deal of attention has been directed recently at the roles played by lipidperoxides in the mediation of pathogenesis and complications of various disease. In view of the strong inhibitory activity of Brazilin on the lipidperoxidation, we examined the effect of Brazilin on the lipidperoxidation in diabetic states. Brazilin inhibited the lipidperoxidation of liver mitochondrial and microsomal fraction in alloxan-induced diabetic ICR mice in the dose and time dependent manner. In the light of the present results, further elucidation of the inhibitory activities of Brazilin on the liver and blood plasma is warrented.
