Total methanol extract of Plantago asiatica seeds showed significant hepatotonic activities against animal model of hepatitis. The methanol extract was further fractionated with petroleum ether, chloroform, n-butanol and water. Among these fractions, methanol extract and water and chloroform fractions exhibited hepatonic activities, whereas petroleum ether and n-butanol fractions appeared to give rise a rather toxicity. Measurements of serum GOT, GPT and duration of sleeping time induced by hexobarbital after $CCl_4$ intoxication indicated that water fraction showed most potent activities.
