title: [Study on flavanols from Glochidion hirsutum].
abstract: OBJECTIVE
  To investigate the flavanols from Glochidion hirsutum.
  
  
  METHODS
  The column chromatographic methods were employed for the isolation and purification of the chemical constituents. The structures were elucidated by spectroscopic methods.
  
  
  RESULTS
  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).
  
  
  CONCLUSIONS
  Compound 1 is a new compound. The other four compounds were isolated from this plant for the first time.
