[Non-alkaloid constituents of Gelsemium elegans].
OBJECTIVE
To study the non-alkaloid chemical constituents of Gelsemium elegans.


METHODS
Compounds were isolated and purified by repeated column chromatography, and their structures were elucidated by spectroscopic methods.


RESULTS
Ten compounds were isolated and their structures were identified as tamarixin (1), tamarixetin 3-O-beta-D-galactopyranoside (2), scopolin (3), scopoletin (4), uradine (5), caffeic acid (6), caffeic acid ethyl ester (7), ferulic acid ethyl ester (8), ethyl-alpha-D-fructofuranoside (9), and ethyl-beta-D-fructopyranoside (10).


CONCLUSIONS
Compounds 1-3,5-10 are firstly isolated from this plant and compounds 1, 2, and 5-10 are isolated from the genus Gelsemium for the first time.
