The protective effects of 67 methanol extracts of crude drugs on rat hepatic injury by carbon tetrachloride (CCl_4) were examined. In terms of the release of intrahepatic enzymes and bilirubin into the blood, 11 methanol extracts decreased these factors significantly. Among them methanol extracts of Caryophylli Flos, Angelicae Dahuricae Radix, Polygoni Avicularis Herba, Myricae Cortex and Forsythiae Fructus were newly found to have protective effects against acute hepatic injury induced by CCl_4. And then these 11 extracts which protected hepatic injury by CCl_4 were investigated for their membrane stabilizing and inhibitory effects of lipid peroxidation. The extract of Bupleuri Radix only decreased the hemolysis induced by hypotonic pressure. Nine kinds of extracts without those of Desmodii Herba and Bupleuri Radix suppressed the lipid peroxidation induced by CCl_4 in rat hepatic microsomes. In addition, Scutellariae Radix, Caryophylli Flos and Myricae Cortex were shown to have inhibitory effects of nonenzymatic lipid peroxidation in rat hepatic mitochondria. This study reports that the methanol extracts of Caryophylli Flos, Angelicae Dahuricae Radix, Polygoni Avicularis Herba, Myricae Cortex and Forsythiae Fructus protect the hepatic injury by CCl_4 and these protective effects are connected with the inhibitory effects of the lipid peroxidation in hepatic microsomes.
