摘要
从广西前胡Peucedaum guangxieuse Shan et Sheh根及根茎的乙醇提取物中，经硅胶柱层析分析8个化合物，分别鉴定为：香豆素化合物广西前胡素（peguangxenin)(1),白花前胡丁素[(+)anomalin](2),伞形花内酯(umbellferone)(3),欧芹属乙素（imperatorin）(4),虎耳草素(pimpinellin)(5);其它类型化合物，falcarindiol(6),阿魏酸(ferulic acid)(7),β-谷甾醇（β-sitosterol）.其中广西前胡素（1）是新化合物，经光谱及化学方法推证其结构为3′(S)-千里光酰氧基-4′（S）-羟基-二氢邪蒿素。
A new coumarin peguangxienin(1), together with 4 known coumarins( + ),anomalin(2) , umbellif erone (3 ) , imperatorin ( 4 ), pimpinellin ( 5 ) , as well as f alcarindiol ( 6 ) , ferulic acid ( 7 ) and (3-sitosterol have been isolated from the roots and rhizomes of Peucedanum guangxiense. The structure of new coumarin peguangxienin (1) has been elucidated as 3' (S)-senecioyloxy-4' (S)-hydroxy-dihy-droseselin by means of spectral and chemical analysis.
