Objective:
To study the chemical constituents of Gekko swinhonis.
Method:
The compounds were isolated and purified by several column chromatographic methods with silica gel, ODS, Sephadex LH-20 and preparative HPLC, Their structures were identified by physicochemical properties and spectral data.
Result:
Thirteen compounds were isolated and elucidated as cyclo-(Pro-Leu) (1), cyclo-(Ala-Pro) (2),cyclo-(Gly-Pro) (3),cyclo-(Ala-Val) (4),6-amino-9-beta-D-ribofuranosyl-9H-purine (5), uridine (6), thymidine (7),hypoxanthine-9-beta-D-ribofuranosid (8),L-phenylalanine (9),5alpha-cholest-3,6-dione (10),cholesterol (11), 1-O-hexadecanolenin (12),octadecanoic acid (13),respectively.
Conclusion:
All compounds were isolated from G. swinhonis for the first time.

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...
