用丙酮提取,石油醚冷冻结晶,从蛇床子中得到混合香豆素。经薄层分离 ,直接进样和质谱分析 ,鉴定出8种香豆素化合物:Ⅰ.蛇床子素(osthol) ,Ⅱ.佛手内酯(bergapten) ,Ⅲ.欧芹属素乙(imperatorin) ,Ⅳ.花椒毒素(xanthotoxin) ,Ⅴ.异回芹内酯(isopimpinellin) ,Ⅵ.别异英波托林(alloisoimperatorin) ,Ⅶ.6 -甲氧基 -8 -甲基香豆精(6_methoxy_8_methylcoumarin) ,Ⅷ.花椒毒酚(xanthotoxol)。其中Ⅵ、Ⅶ首次于蛇床子中发现。
Extracted with acetone, petroleum ether is freeze-crystallized, and mixed coumarin is obtained from the cnidium. After thin layer separation, direct injection and mass spectrometry analysis, eight coumarin compounds were identified: I. Osthol, II. Bergapten, III. Imperatorin, IV. Xanthotoxin, V. isopimpinellin, VI. alloisoimperatorin, VII.6-methoxy-8-methylcoumarin, VIII. Xanthotoxol. Among them, VI and VII were found in Cnidium for the first time.
