• Acacic acid, a pentacyclic triterpenic acid, is present as a saponin in various members of the family Leguminosae, but the highest yield is obtained from the pods of <I>Acacia concinna</I> DC. On the basis of degradative studies, transformations, IR, UV, NMR, mass spectrography, and ORD, and CD studies its absolute stereochemistry and structure have been fixed as 3β, 16β, 21β-trihydroxy-18β-olean-12-en-28-oic acid and that in the acetate the rings E and D are in <I>boat</I> and <I>quasi-boat</I> forms, respectively, with D/E rings <I>cis</I> fused.
