title: [Studies on the chemical constituents from culbs of hybridized Bulbus Fritillariae Ussuriensis].
abstract: OBJECTIVE
  To study the chemical constituents of hybridized Bulbus Fritillariae Ussuriensis.
  
  
  METHODS
  The chemical constituents were isolated by silica column chromatography and their structures were identified by physical and chemical eveidences and spectral analysis (IR, 1H-NMR, 13C-NMR, 2D-NMR, MS).
  
  
  RESULTS
  Seven compounds were obtained and identified as (20S,25S)5alpha, 14alpha, 17beta-cevanine-6beta-hydroxy-3-one (hupehenirine, ZF1), (20S,25S)5alpha, 14alpha, 17beta-cevanine-3beta-hydroxy-6-one (hupehenizine, ZF2), (20R,25S)5alpha, 14alpha-cevanine-3beta,20beta-dihydroxy-6-one (peiminine, verticinone, ZF3), (20S,25S)5alpha, 14alpha, 17beta-cevanine-3beta, 6beta-dihydroxy (hupehenine, ZF4), (20R,25S)5alpha, 14alpha-cevanine-3beta, 6beta, 20beta-trihydroxy (isoverticine, ZF5), (20R,25S)5alpha, 14alpha-cevanine-3beta, 6alpha, 20beta-trihydroxy (peimine, verticine, ZF6), (20S,25S)5alpha, 14alpha, 17beta-evanine-6beta-hydroxy-3beta-O-beta-D-glucoside (hupeheninoside, ZF7).
  
  
  CONCLUSIONS
  Compounds ZF1-7 were isolated from hybridized Bulbus Fritillariae Ussuriensis for the first time.
