30-Noroleanane triterpenoid saponins from Salicornia europaea Linn. and their chemotaxonomic significance

Publication date: June 2018 Source:Biochemical Systematics and Ecology, Volume 78 Author(s): Hui Lyu, Xin Ma, Fuqin Guan, Yu Chen, Qizhi Wang, Xu Feng In the present research, we report the isolation of five 30-noroleanane triterpenoid saponins (1–5), nine oleanane triterpenoid saponins (6–14), and twenty-one other compounds (15–35) from the whole plants of Salicornia europaea Linn. Compound 1, 3-O-β-glucopyranosyl-(1 → 2)-[β-xylopyranosyl-(l→3)]-β-glucuronopyranosyl 30-noroleanolic acid 28-O-β-glucopyranosyl ester, is a previously undescribed nortriterpenoid saponin. The chemical structures were established by detailed analysis of the MS and NMR spectroscopic data or comparison with literature data. Furthermore, the chemotaxonomic significance of 30-noroleanane triterpenoids was discussed in the family Chenopodiaceae and Amaranthaceae. Graphical abstract
