Abstract

Abstract The methanol extract of the stem heartwood of Garcinia brevipedicellata has furnished three new flavonoid C–O–C dimers, brevipedicilones A (6), B (8) and C (10), along with five previously reported flavonoid dimers, viz. amentoflavone (1), 4″′-O-methylamentoflavone (2), robustaflavone (3), 4′-O-methyl robustaflavone (4) and tetrahinokiflavone (5). The new structures, which are composed of flavanone–flavanonol or flavanonol–flavanonol sub-units, were established based on spectroscopic analysis including 1D and 2D NMR (1H-1H COSY, HSQC, HMBC, and NOESY) spectroscopy, and by comparing their spectral data with those reported for related compounds.
