摘要: 应用1H-1H COSY,13C-1H COSY及COLOC并结合其它波谱技术对从中药白花前胡(Peucedanum praeruptorum Dunn)根中分得的一种新化合物前胡香豆素F进行了深入研究,其化学结构确定为3'-异戍烯酰氧基花椒内酯,为吡喃环上3'位烯醇羟基的氧原子和异戍烯酰基形成的烯醇酯.这种新颖结构在自然界中比较少见。

Abstract: The 1H-1H COSY,13C-1H COSY and COLOC spectra as well as UV,HREIMS were used to establish the structurc of qianhucoumarin F isolatcd from the root of Peucedanum praeruptorum Dunn,which is a kind of traditional Chincse medicines.The study of 2D NMR shows that qianhucoumarin F is an ester of enol,its structure was elucidated as 3'-senccioylxanthyletin.This kind of compounds of esters of enol such as qianhucoumarin F has seldom been found in the nature.

Key words: Qianhucoumarin F, 1H-1H COSY, 13C-1H COSY, COLOC
