Two new triterpenic constituents characterized as lupenic arabinopalmitate [lup-12,20(29)-dien-3β-ol-3β-l-arabinofuranosyl-2'-hexadecanoate] (1) and lupenic palmitate [lup-12,20(29)-dien-3β-olyl hexadecanoate] (2) and an aliphatic δ-lactone [4β-(pent-2-enylolactone)-hexatriacontane] (4) have been isolated for the first time from the methanolic extract of the roots of Cichorium intybus L. (Asteraceae) along with the known compound glycery-1-stearyl-2-linolenyl phosphate 3. The structures of all these phytoconstituents have been established by spectral data analysis and chemical reactions.
