Abstract The acetone extract of Alisma rhizomes were found to possess inhibitory effects on vascular contraction induced by high concentration of KCl. With the aids of bioassay, the effective components were pursued by purification with chromatographies, resulting in the characterization of six protostane type triterpenes (alisol C and its analogues) and a known sesquiterpene, alismoxide as the active compounds.
