  From the latex of Lapsana communis L. subps. communis, five guaianolide glycosides were identified: crepiside E, tectoroside and three new ones: 3-O-β-D-glucopyranosyl-8-O-β-acetyl-1αH,5αH,6βH,7αH-guai-4(15),10(14),11(13)-triene-6,12-olide, 3-O-β-D-glucopyranosyl-8-O-β-acetyl-1αH,5αH,6βH,7αH-guai-3(4),10(14),11(13)-triene-15-methyl-6,12-olide, and 3-O-β-glucopyranosyl-8-O-β-(4-hydroxyphenyl)-lactyl-1αH,5αH,6βH,7αH-guai-3(4),10(14),11(13)-triene-15-methyl-6,12-olide. Their structures were established by spectroscopic methods.
