The steroid glycosides in the fresh whole plants of Heloniopsis orientalis (THUNB.) C. TANAKA were examined and the following four steroid saponins were isolated and identified : pennogenin 3-O-rhamnosyl-chacotrioside (II) ; methyl proto-dioscin ; 26-O-β-D-glucopyranosyl-25D-furost-5-ene-3β,17α,22,26-tetraol 3-O-rhamnosyl-chacotrioside (III) (the proto-type compound of II) ; 26-O-β-D-glucopyranosyl-17 (20)-dehydrokryptogenin 3-O-rhamnosyl-chacotrioside (VI) (an artefact produced from III). III is the second furostanol 3,26-O-bisglycoside corresponding to a coexisting pennogenin 3-O-glycoside and could be regarded as a "nolonin".
