Chemical constituents of Tapeinosperma pseudojambosa

Abstract

Examination of the leaves and bark of Tapeinosperma pseudojambosa has shown that, as in other Myrsinaceae, a 'quinone' fraction is obtained in quantity. From the various extracts of the leaves and bark there were obtained the known α- and β-amyrin, bauerenol, quercetrin, primulagenin A and echinocystic acid.
