沙棘叶中4,4′-二羟基-2′-甲氧基查耳酮的分离与鉴定

Isolation and Identification of 4,4′-Diol-2′-methoxychalcone from Leaves of Seabuckthorn

利用硅胶柱和葡聚糖凝胶柱层析 ,从沙棘叶子中分离并鉴定出黄酮类成分 ,进一步分离得到 4 ,4′ 二羟基 2′ 甲氧基查耳酮 。

The 4,4′-diol-2′-methoxychalcone was separated from flavonoids in the leaves of seabuckthorn by Gravity-flow Column Chromatography and Silica Gel Column Chromatography. Then its structure was identified and conformed by Nuclear Magnetic Resonance Spectroscopy.
