Two new triterpenoid saponins have been isolated from the rhizome of plant Acorus calamus. They are characterized as 1β, 2α, 3β, 19α-tetrahydroxyurs-12-en-28-oic acid-28-O-{-β-D-glucopyranosyl(1-2)}-β-D-galactopyranoside 1 and 3β, 22α, 24, 29-tetrahydroxyolean-12-en-3-O-{-β-D-arabinosyl(1-3)}-β-D-arabinopyranoside 2 and their structures elucidated by spectral and chemical studies.
