[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).

CONCLUSION

All these compounds are obtained from Clematis brevicaudata for the first time.
