ABSTRACT
OBJECTIVE:
To study the chemical constituents of Pithecellobium clypearia.METHODS:
The compounds were isolated from Pithecellobium clypearia with column chromatography. Their structures were characterized on the basis of their physical and chemical preperties, as well as chromatographic and spectroscopic evidences.RESULTS:
A pair of isomeric flavans consisting of 7, 3'-O-di-gallyoltricetiflavan (I) and 7,4'-O-di-gallyoltricetiflavan (II), along with a catechin compound (-)-epigallocatechin-7-O-gallate (III) were isolated from the leaves and twigs of Pithecellobium clypearia.CONCLUSION:
Compound I is a new flavan. Compound III is isolated from Pithecellobium genus for the first time, and its 13C-NMR data is firstly given in the present study.
