title: [Chemical constituents of Centipeda minima].
abstract: OBJECTIVE
  To study the chemical constituents from Centipeda minima.
  
  
  METHODS
  The compounds were separated and purified by silica gel, reserved phase silica gel and Sephadex LH-20 gel column chromatography. Their structures were identified on the basis physicochemical property and spectral analysis.
  
  
  RESULTS
  Four chemical constituents were separated from ethyl acetate extracts and five chemical constituents were separated from n-butanol extracts of C. minima and identified as (2R,3R)-(+)-7,4'-di-O-methyldihydrokaempferol (1), iristectorin A (2), 4',5,8-trihydroxy-7-methoxyisoflavone (3), 3-trimethoxyquercetin (4), 3-O-caffeoyl-alpha-glueopyranose (5), 3-O-caffeoyl-beta-glucopyranose (6), quercetin (7), epipinoresinol (8) and hispidulin (9).
  
  
  CONCLUSIONS
  Compounds 1-3, 5-6, 8 and 9 are separated from this genus for the first time.
