Abstract
OBJECTIVE: To study the chemical constituents of the leaf of Clausena lansium (Lour.) Skeels. METHOD: The compounds were isolated by various chromatographic techniques and their structures were elucidated by their physicochemical properties and the analysis of their spectroscopic data. RESULT: Seven compounds were isolated and identified as corchoionoside C (1), 1'-O-beta-D-glucopyranosyl (2R,3S)-3-hydroxynodakenetin (2), quercetin-3-O-robinobioside (3), rutin (4), quercetin-3-O-scillabioside (5), keampferol-3-O-alpha-L-rhamnopyranosyl(1-->2) [alpha-L-rhamnopyranosyl(1-->6)]-beta-D-glucopyranoside (6), mauritianin (7). CONCLUSION: Compounds 1-7 were isolated from the genus Clausena for the first time.
