[Study on the chemical constituents of Cudrania tricuspidata].
OBJECTIVE
To study on the chemical constituents of Cudrania tricuspidata.


METHODS
The chemical constituents were separated by means of silica gel and Sephadex LH-20 chromatography, and their structures were identified by spectra of 1H-NMR, 13 C-NMR.


RESULTS
Seven compounds were isolated and identified as Quercetin (I),5,7,4'-trihydroxyldihydroisoflavone (II), (13alpha, 14beta, 17alpha, 20R)-Lanosta-7, 24-diene-3beta-ol (III), (13alpha, 14beta,17alpha, 20R)-Lanosta-7,24-diene-3beta-0-acetate (IV), Taxifolin (V), Dihydromorin (VI), Cycloartocarpin(VII).


CONCLUSIONS
Compounds III and IV are isolated from the genus for the first time.
