Abstract

Two new flavone rhamnosides, apigenin 7-O-alpha-L-rhamnopyranosyl-(1-->4)-O-alpha-L-rhamnopyranoside and apigenin 7-O-alpha-L-rhamnopyranosyl-(1-->4)-O-alpha-L-rhamnopyranoside-4'-O-alpha-L-rhamnopyranoside were isolated from the fronds of Asplenium normale D. Don, together with two known C-glycosylflavones, vicenin-2 and lucenin-2. The chemical structures of the isolated glycosides were established by UV, LC-MS, characterization of acid hydrolysates, and 1H and 13C NMR spectroscopy.

摘要

从华东铁角蕨的叶片中分离出两种新的黄酮鼠李糖苷，芹菜素7-O-α-L-鼠李吡喃糖基-(1→4)-O-α-L-鼠李吡喃糖苷和芹菜素7-O-α-L-鼠李吡喃糖基-(1→4)-O-α-L-鼠李吡喃糖苷-4'-O-α-L-鼠李吡喃糖苷，同时还分离出两种已知的C-糖基黄酮，异荭草苷和荭草苷。通过紫外光谱、液相色谱-质谱联用、酸水解产物的表征以及1H和13C核磁共振光谱确定了分离出的糖苷的化学结构。
