title: [Studies on the chemical constituents from the bark of Choerospondias axillaries].
abstract: OBJECTIVE
  To study the chemical constituents of Choerospondias axillaries.
  
  
  METHODS
  All compounds were isolated and purified by normal column chromatograph, paper thin layer chromatograph and sephadex chromatograph, the chemical strucures were mainly elucidated by ESI-MS and NMR spectra.
  
  
  RESULTS
  seven compouds were isolated from the Choerospondias axillaries and as following: beta-sitostero (I), hexadecanoic acid (II), correctitude fourty-two alkyl acid (III), daucosterol (IV), quercetin (V), rutinum (VI), lueolin-3'-O-beta-D-glucopyranoside (VII).
  
  
  CONCLUSIONS
  Compounds II, III, V, VII are isolated from this plant for the first time.
