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.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
