[Studies on chemical constituents from stems of Cudrania tricuspidata].
OBJECTIVE
To study the chemical constituents from the stems of Cudrania tricuspidata.


METHODS
The chemical constituents from the ethanol extract of C. tricuspidata were isolated and purified by silica gel, Sephadex LH-20 column chromatographic methods. Their structures were identified on the basis of spectroscopic data and physico-chemical properties.


RESULTS
Thirteen compounds were isolated and identified as butyrospermyl acetate (1), glutinol (2), taraxerone (3), quercetin (4), kaempferol (5), isorhamnetin (6), orobol (7), 3'-O-methyorobol (8), taxifolin (9), naringenin (10), steppogenin (11), 1,3,6,7-tetrahydroxyx-anthone (12), 5,7-dihydroxy chromone (13).


CONCLUSIONS
Compounds 1-3, 6, 13 were isolated from this genus for the first time, while compound 12 was isolated from this plant for the first time and we firstly reported the terpenoids from the genus Cudrania.
