title: [Glycosides of roasted seeds of Cassia obtusifolia].
abstract: OBJECTIVE
  To study the chemical constituents of the roasted seeds of Cassia obtusifolia, and to illuminate the change of its effective components before and after being roasted.
  
  
  METHODS
  The compounds were isolated and repeatedly purified by macroporous resin, silica gel column chromatography. Their structures were elucidated by physical and chemical properties and NMR data.
  
  
  RESULTS
  Three components were obtained from ethanol extract, and the structures were identified as nor-rubrofusarin-6-O-beta-D-(6'-O-acetyl) -glucopyranoside (1), 1-desmethyl- aurantio-obtusin-2-O-beta-D-glucopyranoside (2), obtusin (3).
  
  
  CONCLUSIONS
  Compounds 1 and 2 were isolated from the roasted seeds of C. obtusifolia for the first time, and compound 1 was a new compound.
