Two new lignan glycosides from Saussurea laniceps

Two new lignan glycosides, lanicepsides A and B (1 and 2), along with the eight known compounds 3-6, epipinoresinol, syringin, ethyl caffeate, and 5,6,7-trihydroxy-4'-methoxyflavone, including sesquiterpene lactones, lignans, and a flavone, were isolated from the ethanol extract of Saussurea laniceps. Their structures were determined by spectroscopic methods especially 1D- and 2D-NMR techniques.
