title: [Study on chemical constituents of the bulbs of Lycoris longituba].
abstract: OBJECTIVE
  To study the chemical constituents of the Bulbs of Lycoris longituba.
  
  
  METHODS
  The chemical constituents were isolated and purified by means of chromatographic techniques and their structures were elucidated by spectroscopic methods.
  
  
  RESULTS
  Six compounds were isolated and identified as Crinine (1), Narciclasine (2), Squamigine (3), 11-Hydroxyvittatine (4), Pancracine (5), Lycorine (6).
  
  
  CONCLUSIONS
  Compounds 1 - 6 are isolated from this plant for the first time.
