Chemical constituents of Gekko swinhonis

To study the chemical constituents of Gekko swinhonis.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.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.All compounds were isolated from G. swinhonis for the first time.
