Study on Chemical Constituents of Saussurea laniceps Hand-Mazz.

Objective To study the chemical constituents of Saussurea laniceps from Tibet. Methods Column chromatography techniques were applied for the isolation and purification of the methanol extract of the aerial parts of Saussurea laniceps Hand-Mazz.The structures were elucidated by their physicochemical properties and spectral data. Results Eleven compounds were isolated and identified as syringin(1),isolariciresinol(2),lyoniresinol(3),cycloolivil(4),arctigenin(5),pinoresinol(6),8α-hydroxypinoresinol(7),(+)-syringaresinol(8),methyl-3-(2,4-dihydroxy phenyl)propanoate(9),4-hydroxyacetophenone(10),succinic acid(11). Conclusion Nine compounds(2~9 and 11) were isolated from the species for the first time.
