Objective: To investigate the flavanols from Glochidion hirsutum.
Method: The column chromatographic methods were employed for the isolation and purification of the chemical constituents. The structures were elucidated by spectroscopic methods.
Result: Five 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).
Conclusion: Compound 1 is a new compound. The other four compounds were isolated from this plant for the first time.
