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-dimethoxy-p-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-bis-[2-(4-hydroxyphenyl)ethyl]-2,3-naphthalene dicarboxamide(9). Compounds 1,3,4,9 was separated from Litsea plant for the first time.

Key words: Litsea cubeba (Lour.) Pers., chemical constituent, structure identification
