A new 2′-oxygenated flavone glycoside, named glutin, was isolated from Litsea glutinosa (Lour.) C. B. Rob. along with four known compounds. The structure was identified as 2′,5,7-trihydroxy-6-methoxyflavone 2′-O-β-d-glucopyranoside (1) on the basis of extensive spectroscopic analysis.
从 Litsea glutinosa (Lour.) C. B. Rob.中分离出一种新的 2′-氧合黄酮苷,命名为谷维素,以及四种已知化合物。根据大量光谱分析,确定其结构为 2′,5,7-三羟基-6-甲氧基黄酮 2′-O-β-d-吡喃葡萄糖苷(1)。
