Objective: To study the non-alkaloid chemical constituents of Gelsemium elegans.
Method: Compounds were isolated and purified by repeated column chromatography, and their structures were elucidated by spectroscopic methods.
Result: 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).
Conclusion: 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.
