title: [Study on chemical constituents from rhizome of Rabdosia flavida].
abstract: OBJECTIVE
  To study the chemical constituents from the rhizome of Rabdosia flavida.
  
  
  METHODS
  The compounds were isolated and purified by various chromatographic methods, and their structures were elucidated on the basis of spectral data and physicochemical properties.
  
  
  RESULTS
  Ten compounds were obtained from ethyl acetate fraction of the 70% acetone extract of Rabdosia flavida rhizome and identified as ferruginol (1), dehydrocostuslactone (2), taraxasterol (3), oleic acid (4), ursolic cid (5), coniferyl aldehyde (6), oleanolic acid (7), 6,12, 15-trihydroxy-5, 8,11, 13-abietetra-7-one (8), 5α, 8α-epidioxyergosta-6,22-dien-3β-ol (9), and daucosterol (10).
  
  
  CONCLUSIONS
  All the compounds are isolated from Rabdosia flavida for the first time.
