title: [Alkaloid constituents from silkworm dropping of Bombyx mori].
abstract: OBJECTIVE
  To extract and isolate chemical constituents from the total alkaloids of silkworm dropping (Can Sha) of Bombyx mori L.
  
  
  METHODS
  Chemical constituents were isolated by column chromatography with macroporous adsorbent resin, ion-exchange resin and sephadex LH 20. The structures of the isolated compounds were determined by spectral means.
  
  
  RESULTS
  Three compounds were isolated and identified as 1-deoxynojirimycin (1) , fagomine (2) , and 3-epifagomine (3) on the basis of their 1H-NMR, 13C-NMR spectra and ESIMS data.
  
  
  CONCLUSIONS
  Compounds 1-3 are isolated and identified from Can Sha for the first time.
