Abstract

Two novel angular-type furanocoumarin glycosides, peucedanoside A (1) and peucedanoside B (2), along with a known compound apterin (3), were isolated from the roots of Peucedanum praeruptorum Dunn. Their chemical structures were determined by MS, NMR spectroscopy and chemical analysis. Complete assignments of the 1H and 13C NMR spectroscopic data were achieved by 1D and 2D NMR experiments including DEPT, HSQC, HMBC and ROESY.

摘要

从白花前胡（Peucedanum praeruptorum Dunn）的根部分离出两种新型角型呋喃香豆素糖苷，白花前胡苷A（1）和白花前胡苷B（2），以及一种已知化合物apterin（3）。通过质谱、核磁共振光谱和化学分析确定了它们的化学结构。通过包括DEPT、HSQC、HMBC和ROESY在内的一维和二维核磁共振实验完成了1H和13C核磁共振光谱数据的完全归属。
