Abstract: Seven compounds were isolated from the underground parts of Saussurea lappe in-cluding three steroids, pregnenolone (1), β-sitosterol (2), daucosterol (3); a phenylpropanoid glycoside, syringin (4); a lignan glycoside, l- hydroxypinoresinol-l-β- D- glucopyrano side (5); a straight chain fatty acid and an its propanedinyl ester, (z, z) -9, 12 -octadecadienoic acid (6), (z,z)- 9, 12 -octadecadienoic acid -2- hydroxy -1, 3 -propanedinyl ester (7). The structures of these compounds were determined by means of spectral and some chemical evidence. Moreover, among the seven compounds, compound 1 as a natural product has been isolated from plantS for the first time, compounds 3,4,5 and 7 have been obtained from this plant source for the first time.
