从芹菜(Apium graveolens)种子中获得一个新香豆素命名为celerin,另分离得2种已知香豆素osth-enol,apigranin和对羟基肉桂酸。方法:干燥的芹菜种子,用石油醚,苯和乙醚连续提取,浓缩石油醚部分,经硅胶层析,以石油醚→苯梯度洗脱,先下来的部分有6个香豆素,再用制备性薄层层析(硅胶,丙酮-苯1:4)。从苯洗脱的部分,在稀甲醇中 One new coumarin from celery (Apium graveolens) seeds was named celerin, and two other known coumarin isoth-enol, apigranin and p-hydroxycinnamic acid were isolated. METHODS: Dried celery seeds were continuously extracted with petroleum ether, benzene and ether. The petroleum ether fractions were concentrated and chromatographed on silica gel with gradient elution of petroleum ether - benzene. The first portion of the coumarin was eluted with 6 coumarins followed by preparative Thin layer chromatography (silica gel, acetone-benzene 1: 4). The portion eluted from the benzene is in dilute methanol
