[Chemical constituents of Clausena lansium].
OBJECTIVE
To study the chemical constituents of the leaf of Clausena lansium (Lour.) Skeels.


METHODS
The compounds were isolated by various chromatographic techniques and their structures were elucidated by their physicochemical properties and the analysis of their spectroscopic data.


RESULTS
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).


CONCLUSIONS
Compounds 1-7 were isolated from the genus Clausena for the first time.
