Abstract

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
