title: [Studies on chemical constituents from Zephyranthes candida].
abstract: OBJECTIVE
  To study on the chemical constituents of Zephyranthes candida.
  
  
  METHODS
  Compounds were isolated and repeatedly purified by chromatographic techniques on silica gel column. Their structures were elucidated by chemical and spectral methods.
  
  
  RESULTS
  Eight compounds were isolated from the whole plant of Zephyranthes candida, and identified as (2S)-3',7-dihydroxy-4'-methoxyflavan (I), beta-sitosterol (II), stigmasta-5,22-dien-3beta-ol (III), stigmasterol (IV), beta-daucosterin (V), Butylisobutyl phthalat (VI), Heptacosane (VII) and Ambrettolide (VIII).
  
  
  CONCLUSIONS
  I-XIII are all isolated from this plant for the first time.
