Investigation of the constituents of the aerial parts of domestic plant species Picris echoides afforded the sesquiterpene lactones, i.e., guaianolides jacquilenin (1), 11-epi-jacquilenin (2), achillin (3) and eudesmanolide telekin (4). The chemical indentification of the two monoterpene glucosides (-)-cis-chrysanthenol-b-D-glucopyranoside (5) and its 6’-acetate 6 is also repoted. The guaianolide achillin (3) and the two monoterpene glucosides 5 and 6 were isolated for the first time from this plant species. Isolation was achieved by column chromatography and the structures were established mainly by the interpretation of their physical and spectral data, which were in agreement with those in the literature.
