摘要
本文研究了长白山臭冷杉(Abies nephrolepis Maxim)挥发油的化学成分,用毛细管气相色谱和 GC/MS/DS 联用法从46个色谱峰中鉴定了22个成分。主要成分为α-蒎烯、莰烯、柠檬烯、乙酸龙脑酯。鉴定出的组分占总挥发油的96.8％。应用氮气保护下精密分馏技术、制备旋转薄层色谱、柱层析等方法从臭冷杉叶挥发油中分出了6种纯化合物,用 IR、MS 确证其中4个化合物为柠檬烯、龙脑、乙酸龙脑酯、α-甜没药醇。
The volatile oil of Abies nephrolepis Maxim leaves growing in Changbai Moutain region was analyzed by OV-1 Capillary column (25×0.25)GC/MS/DS and found to contain 46 che- mical constituents,22 of them which make up 96.8% of the total oil were identified.The major components are α-pinene (15.944%),camphene (20.329%),limonene (29.709%),bornyl acetate (17.083%),etc. Six components from the oil were isolated by N_2 protected vectification under vacuum, preparative circle thin-layer chromatography and column chromatography.Limonene,borneol, bornyl acetate and α-bisabolol were idetified by IR and MS.
