Three triterpenoid saponins were isolated from legumes of Gleditsia japonica cv.'Saponifera'(Leguminosae). These saponins are rare examples of triterpenoid saponins containing monoterpenes. The desmonoterpenyl compound, C74H120O38, [α]23D -42.3°(MeOH), which was obtained from them by alkali hydrolysis with K2CO3, was characterized as a 3, 28-O-bisglycoside on the basis of physical data and degradation products.
