A new lignan epoxide together with the seven known lignans: pinoresinol, pinoresinol-O-beta-D-glucopyranoside, pinoresinol monomethyl ether-O-beta-D-glucopyranoside, lariciresinol, lariciresinol-4-O-beta-D-glucopyranoside, lariciresinol-4'-O-beta-D-glucopyranoside, and syringaresinol monoglucopyranoside were isolated from the hydroalcoholic and organic extracts of the whole plant of Phillyrea angustifolia L. (Oleaceae). The structure of the new constituent was elucidated by spectroscopic methods (UV, IR, and 1D- and 2D-NMR) and by mass spectrometry (HR-ESI-MS), mainly using 2D-NMR techniques. The effects of these compounds on germination and growth of dicotyledon Lactuca sativa L. (lettuce) were studied in the 10(-4) to 10(-7) M concentration range

Abstract
A new lignan epoxide together with the seven known lignans: pinoresinol, pinoresinol-O-beta-D-glucopyranoside, pinoresinol monomethyl ether-O-beta-D-glucopyranoside, lariciresinol, lariciresinol-4-O-beta-D-glucopyranoside, lariciresinol-4'-O-beta-D-glucopyranoside, and syringaresinol monoglucopyranoside were isolated from the hydroalcoholic and organic extracts of the whole plant of Phillyrea angustifolia L. (Oleaceae). The structure of the new constituent was elucidated by spectroscopic methods (UV, IR, and 1D- and 2D-NMR) and by mass spectrometry (HR-ESI-MS), mainly using 2D-NMR techniques. The effects of these compounds on germination and growth of dicotyledon Lactuca sativa L. (lettuce) were studied in the 10(-4) to 10(-7) M concentration rangeI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
