Abstract:
OBJECTIVETo study the chemical constituents from the leaves of Boehmeria nivea.
METHODThe leaves were extracted by 95% EtOH at room temprature, the chemical leaves were isolated and purified by repeated silica gel column chromatography, Sephadex LH-20 column chromatography and semipreparative HPLC, and their structures were identified by physical and chemical properties and spectroscpoic methods.
RESULTOne compound isolated from n-butanol fraction, four compounds were obtained from ethyl acetate fraction and three compounds from petroleum ether fraction. Their structures were elucidated as kiwiionoside (1), eugenyl beta-rutinoside (2), uracil (3), beta-sitosterol glucoside (4), 3-hydroxy-4-methoxy-benzoic acid (5), cholesterol (6), alpha-amyrin (7). nonacosanol (8).
CONCLUSIONCompounds 1-3, 5-8 were isolated from the genus Boehmeria for the first time.
