Abstract:
OBJECTIVETo investigate the flavanols from Glochidion hirsutum.
METHODThe column chromatographic methods were employed for the isolation and purification of the chemical constituents. The structures were elucidated by spectroscopic methods.
RESULTFive flavanols were isolated and identified as 3-O-(3-methylgalloyl) catechin (1), 3-O-( 3-methylgalloyl) gallocatechin (2), 3-O-galloylgallocatechin (3), gallocatechin (4), catechin (5).
CONCLUSIONCompound 1 is a new compound. The other four compounds were isolated from this plant for the first time.
