title: [Studies on chemical constituents from flowers of Chrysanthemum indicum].
abstract: OBJECTIVE
  To study the chemical constituents of the flowers of Chrysanthemum indicum.
  
  
  METHODS
  Chemical constituents were isolated and purified by silica gel and Sephadex LH-20 column chromatography. The structures were identified by means of physico-chemical and spectral data.
  
  
  RESULTS
  From the 80% ethanol extract of the material, seven compounds were isolated. Their structures were identified as acacetin(1), acacetin-7-O-(6"-O-acetyl) beta-D-glucopyranoside (2), linarin (3), apigenin-7-O-beta-D-glucopyranoside(4), chlorogenic acid (5), vanillic acid(6) and sucrose(7), respectively.
  
  
  CONCLUSIONS
  Compounds 2, 4, 6 and 7 are isolated from C. indicum for the first time.
