Chemical investigation on the constituents of the ethyl acetate soluble extraction of Litsea cubeba has resulted in the isolation and structure elucidation of thirty compounds, including one sesquiterpene(1), four monoterpenes(2-5), two γ-butyrolactone derivatives(6 and 7), seven tyramine derivatives(8-14), fifteen aromatic compounds(15-29), and one pyrone derivative(30) via various chromatographic techniques and spectroscopic data analysis(MS, IR, 1 D and 2 D NMR). Compounds 1-7, 13 and 14 were obtained from the genus Litsea for the first time.
