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

Abstract 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.
