龙脑樟叶脱脑油成分分析

摘要

对用挥发油提取器提取得到的龙脑樟叶油进行真空抽滤，获得其脱脑油，再利用气相色谱-质谱联用仪和气相色谱仪对晶体及脱脑油进行了定性和定量分析。试验结果表明，真空抽滤是纯化龙脑樟叶油的可用方法之一；脱脑油中单萜类物质占总量的85.467%（相对质量分数），主要成分为为龙脑（23.813%）、D -苧烯（15.627%）、α-蒎烯（12.593%）、莰烯（6.309%）、β-月桂烯（6.213%）、乙酸龙脑酯（6.153%）和β-蒎烯（4.336%）等，可通过分馏对其加以利用。%The de-crystallized leave oil ofCinnamomum Camphora(L)Sieb was obtained by vacuum suction filtration of the volatile oil extracted. The chemical constituents and their relative contents of crystal and de-crystallized leave oils were quantitatively and qualitatively analyzed by means of GC-MS and GC with area normalization. The results showed that vacuum suction filtration was one of purification methods for leave oil ofCinnamomum Camphora(L)Sieb. The relative mass contents of monoterpenes in de-crystallized oil were more than 85.467%,the major components were endo-borneol(23.813%),D - limonene(15.627%),α - pinene(12.593%), camphene(6.309%),β - myrcene(6.213%), bornyl acetate(6.153%),β - pinene(4.336%), etc. This oil could be utilized after fractional distillation.
