Abstract: Sixteen compounds were isolated from the aerial parts of Saussurea japanica (Thunb) DC. and their structures were identified by spectroscopic methods. Three of them were new. kaempferol-3-O-(6"-O-crotonyl)-β-D-glucoside(I), quercetin-3-O-(6"-O-crotonyl)-β-D-glucoside(2), and syringin methyl ether(3); the others were known compounds; kaempferol-3-O-β-D)-glucoside, quercetin-3-O-β-D-glucoside, syringin,α-amyrinyl palmitate,β-amyrinyl palmitate, lupeol palmitate, lupeol acetate, lupeol, β-sitosterol, palmitic acid, tetracosanic acid, cerotic acid, and pentacosane.

Key words: Saussurea japanica(Thunb) DC.,Flavonol glycoside, Syringin methyl ether
