[Chemical constituents of the aerial parts of Rhamnus crenatus].
OBJECTIVE
To study chemical constituents of the aerial parts of Rhamnus crenatus sieb. et zucc.


METHODS
The chemical constituents were isolated by chromatographic methods and their structures were elucidated on the basis of spectral analysis.


RESULTS
Five compounds were isolated and their structures were identified as crenatoside (1), torachrysone (2), emodin (3), emodin-1-O-beta-D-glucopyranoside (4) and beta-sitosterol (5) respectively.


CONCLUSIONS
Compound 1 is a new compound and the others were isolated from Rhamnus crenatus for the first time.
