Abstract
In order to isolate the hypocholesterolemic principle, the neutral ethyl acetatesoluble fraction of the methanol extract of Alismatis Rhizoma was fractionated in parallel with the biological test. Thus new compounds alisol A (1), alisol B (2), alisol A monoacetate (3), alisol B monoacetate (4) and alisol C monoacetate (5) were obtained. The compounds 1, 3, 4 and 5 were shown to be effective in the test with rats.
