✦ Synopsis

Abstract

Ten 8‐(3,3‐dimethylallyl)‐substituted flavonoid glycosides, including the four new flavonol glycosides 1 and 3–5 and the new flavanonol glycoside 2, besides five known flavonol glycosides, were isolated from the aerial parts of Epimedium koreanum Nakai. Their structures were determined by spectroscopic methods, including UV, IR, 1D‐ and 2D‐NMR, ESI‐MS^n^, HR‐ESI‐MS, and circular dichroism (CD) experiments.
