title: [Study on the chemical constituents from Clematis brevicaudata].
abstract: OBJECTIVE
  To study the chemical constituents from Clematis brevicaudata.
  
  
  METHODS
  The compounds were isolated by column chromatography and their structures were elucidated through spectroscopic analysis (NMR).
  
  
  RESULTS
  Eight compounds were isolated and identified as: palmitic acid (1), 1-docosanol (2), pentacosanoic acid-2', 3'-dihydroxypropyl ester (3), beta-sitosterol (4), daucosterol (5), a mixture of the trans-p-coumarate of the n-alkanols (6), 3,4-dihydroxy-trans coumatate ethyl ester (7), syringaresinol-O-D-glucopyranoside (8).
  
  
  CONCLUSIONS
  All these compounds are obtained from Clematis brevicaudata for the first time.
