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