摘要
【目的】观察不同提取方法对檀香挥发油含量及成分的影响。【方法】应用气相色谱—质谱—计算机联用技术 ,对乙醚浸渍法及溶剂回流法所得的檀香油与水蒸汽蒸馏得到的挥发油质量进行了比较研究。【结果】乙醚浸渍法所得檀香油中总檀香醇的比率稍大于以水蒸汽蒸馏所得挥发油 ,且二者化学成分的组成及比例相类似。经石油醚回流及乙醇回流所得挥发油比率高于水蒸汽蒸馏法 ;其总檀香醇的含量及其他化学成分含量则与之相近。【结论】乙醚浸渍法可用于檀香挥发油的定性分析。以水蒸汽蒸馏法提取檀香油难以提取完全。
Objective To observe the influences of ether soaking method, solven t refluxing method and steam distilling method on the content and chemical compo nents of volatile oil from Lignum Santali. Methods Gas chromatograph_mass sp ectrogram (GC_MS) analysis was adopted. Results The content of santalol in t he oi l from Lignum Santali extracted by ether soaking was a little higher than that i n the volatile oil extracted by steam distilling, and their chemical components are similar. The total content of volatile oil extracted by solvent refluxing me thod was 3.35%, much higher than that by steam distilling metho d. GC_MS analysis showed the content of santalol and other chemical components a re similar by the two methods. Conclusion Ether soaking method can be used f or the qualitative analysis of volatile oil from Lignum Santali. Extraction of s antalum oil by steam distilling method is incomplete.
