title: [Studies on chemical constituents from rhizomes of Panax notoginseng].
abstract: OBJECTIVE
  To study the chemical constituents from rhizomes of Panax notoginseng.
  
  
  METHODS
  The constituents were isolated and purified by various chromatogragraphic methods, all compounds were identified on the basis of special analysis and physicochemical characters.
  
  
  RESULTS
  Eight compounds were isolated from the 80% alcohol extract of the rhizomes and their structures were identified as ginsenoside Rh4 (I), ginsenoside Rh1 (II), ginsenoside Re (III), notoginsenoside R1 (IV) , ginsenoside Rd (V), ginsenoside Rh1 (VI), notoginsenoside S (VII), notoginsenoside T (VIII).
  
  
  CONCLUSIONS
  Compound I was isolated from this plant for the first time, Compound VII, VIII are isolated from rhizomes of Panax notoginseng for the first time.
