title: [Chemical constituents of glucoside fraction from Liuwei Dihuang Gantang].
abstract: OBJECTIVE
  To study chemical constituents of glucoside fraction from Liuwei Dihuang Gantang and clarify its substance foundation of active constituents.
  
  
  METHODS
  Glucoside fraction was prepared by macroporous resin chromatography. Constituents were separated by silica gel and reverse phase silica gel column chromatography, and their structures were identified by MS and NMR.
  
  
  RESULTS
  Eleven compounds were separated and identified as 7-dehydrologanin (1), 7alpha-O-methylmorroniside (2), 7beta-O-methylmorroniside (3), 7alpha-O-ethylmorroniside (4), 7beta-O-ethylmorroniside (5), morroniside (6), sweroside (7), loganin (8), paeoniflorin (9), paeonolide (10) and loganic acid (11).
  
  
  CONCLUSIONS
  All of those compounds were separated from Liuwei Dihuang Gantang for the first time.
