ResumoAn investigation of the leaves of Castanospermum australe afforded one new and another known triterpenoid saponin as their methyl esters. The structures of these two compounds were elucidated on the basis of chemical and spectral data as 2β,23-dihydroxy-3-O-(4-deoxy-β-l-threo-hex-4-enopyranosiduronic acid)-olean-12-en- 28-oic acid dimethyl ester and medicagenic acid 3-O-β-d-glucoside dimethyl ester.
