Flavanoids from the Stembark of Chisocheton pentandrus (Meliaceae)

Abstract

Two flavanoid compounds, catechin (1) and epicatechin (2), have been isolated from the stembark of Chisocheton pentandrus. The chemical structure of compounds1and2were identified byspectroscopic data including, UV, IR, NMR (1H, 13C, DEPT 135°, HMQC, HMBC, 1H-1H COSY) and MS and by comparing with previously reported spectral data. Compounds 1 and 2, were isolated in this plant for first time and showed no cytotoxic activity against MCF-7 breast cancer cells.
