The pods of Acacia oonalnna D.C. by aloohollc extraotion yields a oolourless saponln, whlah on hydrolyeis with rulphurlo acid yields an acid genin, m.p.26S-72°, dlaoetyl la&one m.p.235-350. This acid has been Identified ae aoaoio acid (I)' by mixed melting point with authentlo samples of acaola acid and It.6 aoetyl laotone reapeotively, (Cf.Aoaclo acid m.p.375-16°; aoaolo aold ace&y1 laotone ~.p.235-36~)~. Aoaclo acid la a sapogenin of fairly oommon ooourrenoe.
