Abstract: The constituents of the stem of Cinamonum Camphora were isolated by column chromatography on silicagel,polyamide and recrystallization.Their structures were elucidated by physicochemical properties and spectral analysis.Ten compounds were isolated and identified as β-sitosterol ( 1),quercetin(2),kaempferol(3 ),(8R, 8′R)-3,3′,4,4′-tetramethoxy-9-oxo-8-8′,9-O-9′lignans( 4),daucosterol(5 ),Quercetin-3-O-β-D-glucoside(6), Quercetin-3-O-α-L-rhamnoside (7),Quercetin-3-O-β-D-glucoside ( 8), rutin(9),oleanolic acid(10).Compound 1,2,3,5,6,10 were obatained from Cinamonum Camphora for the first time.

Key words: Cinamomum Camphora, rutin, kaempferol, oleanolic acid, quercetin
