Abstract
Abstract:The chemical constituents were isolated and purified by column chromatography over silicagel,Sephadex LH-20 column chromatography and preparative TLC in 95 % alcohol extract of Litsea cubeba (Lour.) Pers.Nine compounds were isolated and identified on the basis of physicochemical properties and spectral data,i.e.,β-sitostenone (1),β-sitosterol (2),2,5-dimethoxyp-benzoquinone(3),2,6-dimethoxy-p-benzoquinone(4),N-transferuloyl-3-methyldopamine(5),N-trans-feruloyl tyramine(6),N-p-coumaroyltyramine(7),daucosterol(8) and 1,2-dihydro-6,8-dimethoxy-7-1-(3,5-dimethoxy-4-hydroxyphenyl)-N1,N2-his[2-(4-hydroxyphenyl)ethyl]-2,3-naphthalene dicarboxamide(9).Compounds 1,3,4,9 was separated from Litsea plant for the first time.关键词
