摘　　要：Two new sesquiterpene lactone glycosides were isolated from the whole plant of Sonchus transcaspicus. Their structures were elucidated as 1β-O-β-D-glucopyranosy-5α, 6β H-eudesma-3-en-12, 6α-olide and 1β-O-β-D-glucopyranosy-15-O-(p-hydroxylphenylacetate)-5α, 6β H-eudesma-3, 11(13)-dien-12, 6α-olide by spectral methods (HRMS, 1D and 2D NMR).Two new sesquiterpene lactone glycosides were isolated from the whole plant of Sonchus transcaspicus.
