Triterpenoids from Phytolacca acinosa, three oleanane derivatives

Abstract In addition to 30-methylspergulagenate, three new oleanane derivatives, spergulagenic acid A, isophytolaccinic acid A and isophytolaccagenin A have been isolated and characterized from the alcoholic extract of the defatted berries of Phytolacca acinosa . The new compounds have been identified as 3β-acetoxy-30β-methyloleanate-12-en-28β-oic acid; 3β,23α-diacetoxy-28β-methyloleanate-12-en-30β-oic acid and 2β, 3β,23α-triacetoxy-28β-methyloleanate-12-en-30β-oic acid, respectively.
