title: [Studies on flavonoids from the leaves of Lindera aggregata].
abstract: OBJECTIVE
  To investigate the chemical constituents in the leaves of Lindera aggregate.
  
  
  METHODS
  Compounds were separated by column chromatography with silica gel and ODS. The structures were identified by physicochemical properties and spectral analysis (1H-NMR, 13C-NMR).
  
  
  RESULTS
  Eight compounds were isolated and identified as: quercetin-3-O-L-rhamnoside(1), kaempferol-3-O-L-rhamnoside(2), kaempferol(3), dihydrokaempferol-3-O-L-rhamnoside (4), quercetin (5), quercetin-3-O-alpha-D-arabinofuranoside (6), quercetin-3-O-alpha-D-glucopyranoside(7), kaempferol-3-O-D-glucopyranoside(8).
  
  
  CONCLUSIONS
  Compounds 2,4 and 8 are obtained from Lindera aggregata for the first time.
