摘要

利用液质联用技术对菊苣(Cichorium intybus Linn.)根、茎和叶中的化学成分进行分析。结果显示:菊苣中含有绿原酸和3,5-二咖啡酰奎宁酸2个酚酸类成分以及菊苣萜苷B、11β,13-二氢山莴苣素、山莴苣素、山莴苣苦素、8-脱氧山莴苣素、notoserolide A和假还阳参苷B 7个倍半萜内酯类成分。各成分含量在根、茎和叶中存在显著差异,叶中各酚酸类成分含量均最高,绿原酸含量(6.877 mg·g-1)分别为根和茎中的18.0和208.4倍,3,5-二咖啡酰奎宁酸含量(3.583 mg·g-1)分别为根和茎中的53.5和14.2倍;茎和叶中各倍半萜类成分含量总体上高于根,其中,茎中山莴苣素、山莴苣苦素和notoserolide A含量最高,叶中11β,13-二氢山莴苣素、8-脱氧山莴苣素和假还阳参苷B含量最高。综上所述,菊苣地上部分含有丰富的次生代谢产物,开发利用价值较高。

Abstract

The chemical components in root, stem, and leaf of Cichorium intybus Linn. were analyzed by using liquid chromatography-mass spectrometry technology. The results show that there are two phenolic acids namely chlorogenic acid and 3,5-dicaffeoylquinic acid and seven sesquiterpene lactones namely cichorioside B, 11β,13-dihydrolactucin, lactucin, lactucopicrin, 8-deoxylactucin, notoserolide A, and crepidiaside B in C. intybus. There are significant differences in content of each component among root, stem, and leaf, and content of each phenolic acid in leaf is the highest, in which chlorogenic acid content (6.877 mg·g-1) is 18.0 and 208.4 times higher than those in root and stem respectively, and 3,5-dicaffeoylquinic acid content (3.583 mg·g-1) is 53.5 and 14.2 times higher than those in root and stem respectively; content of each sesquiterpene lactone in stem and leaf is generally higher  than that  in root, in which, contents of lactucin, lactucopicrin, and notoserolide A in stem are the highest, while contents of 11β,13-dihydrolactucin, 8-deoxylactucin, and crepidiaside B in leaf are the highest. In conclusion, the above-ground part of C. intybus is rich in secondary metabolites and has relatively high development and utilization value.
