Spinosic acid A, one of the sapogenins from Randia spinosa, has been shown to be 3β, 19β-dihydroxyolean-12-en-28-oic acid. Other sapogenins isolated include oleanolic acid, siaresinolic acid, and another new triterpenoid, spinosic acid B. The sterols, β-sitosterol and stigmasterol have also been obtained.
