title: [Chemical constituents from Faeces bombycis].
abstract: OBJECTIVE
  To study the chemical constituents from Faeces bombycis.
  
  
  METHODS
  Isolation and purification were carried out on silic gel, Sephadex LH-20 and RP-18 column chromatography. The chemical structures of the constituents were elucidated on the basis of physicochemical properties and spectral data.
  
  
  RESULTS
  Fifteen compounds were identified as 3S, 5R-dihydroxy-6R, 7-megstigmadien-9-one (1), 3S, 5R-dihydroxy-6S, 7-megstigmadien-9-one (2), (6R, 9R)-3-oxo-alpha-ionol-beta-D-glucopyranoside (3), (6R, 9S)-3-oxo-alpha-ionol-beta-D-glucopyranoside (4), blumenol C glucoside (5), byzantionoside B (6), alangionoside L (7), lutein (8), pipecolic acid (9), betaine (10), alanine (11), glutamic acid (12), phenylalanine (13), leucine (14), isoleucine (15).
  
  
  CONCLUSIONS
  All the compounds were separated from Faeces bombycis for the first time.
