Icariside II, a flavonol glycoside, was isolated from the aerial part of Epimedium Koreanum Nakai by the anti-hepatotoxic acitivity guided fractionation technique employing $CCl_4-in-toxicated$ primary cultured rat hepatocytes as an assay system. Its anti-hepatotoxic activity was evaluated by measuring activity of glutamic pyruvic transaminase released from the $CCl_4-in-toxicated$ primary cultured rat hapatocytes. Icariside II significantly reduced the activity of glutamic pyruvic transaminase released from the $CCl_4-in-toxicated$ primary cultured rat hepatocytes and resulted in 78% recovery of the toxicity at the concentration of $200{\;}\mu\textrm{m}$. The anti-hepatotoxic activity of icariside II on the $CCl_4-in-toxicated$ primary cultured rat hepatocytes was as potent as that of silybin.
