石莲姜槲蕨化学成分研究

Studies on the Chemical Constituents of Drynaria propinqua(Wall)J. Sm.

从川产石莲姜槲蕨中分离鉴定了4个化合物,其中(-)-表阿夫儿茶精-3-O-β-D-吡喃阿洛糖甙为一新的天然产物,命名为石莲姜素,另外3个化合物分别为4-O-β-D-吡喃葡萄糖基咖啡酸,胡萝卜甙和蔗糖。

Four compounds isolated from the rhizomes of Drynaria propinqua collected in Sichuan have been identified. One of them was a new natural product, namely propinqualin, whose structure was established as (—)-epiafzelechin-3-O-β-D-allopyranoside. The other three were 4-O-β-D-glucopyrauosyl caffeic acid, β-sitosterol-3-O-β-D-glucopyranoside and sucrose.
