The leaf of Phyllostachys bambusoides S. et Z. (Gramineae) has been used in traditional herbal medicine as a antipyretics, antitussives and antidiuretcs, etc, in Korea, China and Japan. In order to investigate the effects on antilipoperoxidation and liver protective effect, the leaf of Phyllostachys bambusoides S. et Z. was extracted by water and then fractionated with butanol. The water extract and BuOH soluble fraction strongly exhibited antilipoperoxidatant effect in rat liver homogenate intoxicated with $CCl_4$. The BuOH fraction significantly suppressed the increases of s-GOT, s-GPT and s-LDH activities in injuried rats induced by $CCl_4$. And the BuOH fraction inhibited significantly the decrease of the body weight and showed the antilipoperoxidatant effect in liver and kidney in $CCl_4$ intoxicated rats.
