title: [Studies on chemical constituents of Cuscuta chinensis].
abstract: OBJECTIVE
  To study the chemical constituents of the seeds of Cuscuta chinensis.
  
  
  METHODS
  The separation was carried out by polyamide and silica gel chromatography, and the compounds were identified by means of physico-chemical and spectroscopic methods.
  
  
  RESULTS
  Eight compounds were isolated from the plant and identified as quercetin 3-O-beta-D-galactoside-7-O-beta-D-glucoside (I), quercetin 3-O-beta-D-apiofuranosyl-(1-->2)-beta-D-galactoside (II), hyperoside (III), isorhamnetin (IV), kaempferol (V), quercetin (VI), d-sesamin (VII) and 9(R)-hydroxy-d-sesamin (VIII).
  
  
  CONCLUSIONS
  Compounds IV and VII were isolated from Cuscuta for the first time, and I, II and VIII were characteristic constituents for this vegetable drug.
