ABSTRACT

To study the chemical constituents from Clematis brevicaudata. The compounds were isolated by column chromatography and their structures were elucidated through spectroscopic analysis (NMR). 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). All these compounds are obtained from Clematis brevicaudata for the first time.
