本文采用正相硅胶柱、MCI柱、Sephadex LH-20及半制备HPLC从柳兰(Chamerion angustifolium)乙醇提取物中分离到一个新的异香豆素,命名为柳兰内酯甲素(1),通过二维核磁共振、旋光等波谱学分析方法确定了其结构。
In this paper, a new isocoumarin was isolated from the ethanol extract of Chamerion angustifolium by normal phase silica gel column, MCI column, Sephadex LH-20 and semi-preparative HPLC. Its structure was confirmed by two-dimensional nuclear magnetic resonance and optical rotation spectroscopy.
