Novel Secoiridoid Glucosides in Olea europaea Leaves Suffering from Boron Deficiency

概要

論文の詳細を見る
From the methanol extract of boron deficient Olea europaea leaves, two secoiridoid glycosides, not detected in leaf extracts of untreated plants, 6′-E-p-coumaroyl-secologanoside and 6′-O-[(2E)-2,6-dimethyl-8-hydroxy-2-octenoyloxy]-secologanoside, were isolated together with three known secoiridoid glycosides, oleuropein, oleoside dimethyl ester, and secologanoside. The structures of the isolated compounds were established by means of NMR and MS spectral analyses. The above novel secoiridoids were synthesized by the plant as a physiological response to nutrient stress.
