概要
OBJECTIVE
To study the chemical constituents of Cudrania cochinchinensis.
METHODS
Compounds were isolated and purified by silica gel column, sephadex LH-20 chromatography and recrystallization. Their structures were elucidated by physicochemical properties and spectral data.
RESULTS
Thirteen compounds were isolated from the 70% ethanol extract of the root of Cudrania cochinchinensis and identified as beta-sitosterol (1), butyrospermol (2), butyrospermol acetate (3), (+) syringarenol (4), 1, 3, 6-trihydroxy-7-methoxy xanthone (5), 1, 3, 6, 7-tetrahydroxy-8-prenylxanthone (6), kaempferol (7), dihydrokaempferol (8), umbelliferone (9),4-hydroxybenzyl ethyl ether (10), 2,4-dihydroxybenzaldehyde (11), 4-hydrox-ybenzaldehyde (12) and vanillin (13).
CONCLUSIONS
Compounds 2 - 6, 10 - 13 are isolated from Cudrania cochinchinensis for the first time.
