Two new sesquiterpene lactones, namely 8‐ O ‐methylsenecioylaustricin ( 1 ) and epi‐8 α ‐angeloyloxycichoralexin ( 2 ), as well as a new triterpene glycoside (taraxasterol‐3‐ O ‐ β ‐ D ‐glucoside, 3 ), together with the three known sesquiterpene lactones lactucin ( 4 ), lactucopicrin ( 5 ), and 11 β ,13‐dihydrolactucin ( 6 ), were isolated from the stems of Cichorium glandulosum Boiss. et Huet . The chemical structures were elucidated on the basis of spectroscopic methods.
