[Study on the chemical constituents from Clematis brevicaudata].

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).
