From the roots of Lactuca tatarica, one new and two known guaianolides were isolated together with five known guaianolide glycosides, three known germacrolide glycosides and benzyl-β-glucopyranoside. The structure of the new compound was elucidated as 11(β)H, 13-dihydrolactucin-8-O-p-methoxyphenylacetate by spectral methods.
