摘要

A novel macrocyclic flavonoid glycoside, angustifolinoid A (1), featuring an unprecedented 13-membered heterocyclic ring moiety, along with a known flavonoid glycoside, tiliroside (2), were isolated from Elaeagnus angustifolia flowers. Their structures were determined by extensive spectroscopic analysis and electronic circular dichroism (ECD) calculation. Biosynthesis analysis indicated that compound 1 might be derived from compound 2 via a key enzymatic intramolecular oxidative coupling. Compounds 1 and 2 showed inhibitory activities against cyclooxygenases, COX-1 and COX-2. (C) 2018 Elsevier Ltd. All rights reserved.
