摘要
[目的]明确不同提取方法对莪术挥发油中β-榄香烯含量的影响。[方法]采用水蒸气蒸馏法和石油醚提取法提取莪术挥发油,气相色谱法(gas chromatography,GC)法测定莪术油中β-榄香烯的含量,比较不同方法提取莪术挥发油中β-榄香烯含量的差异。[结果]水蒸气蒸馏法提取的莪术油中β-榄香烯的含量高于石油醚提取。[结论]水蒸气蒸馏法提取莪术挥发油效率较高。
[Objective]To observe the content of β-elemene in this oil by different methods.[Methods]Steam distillation and petroleum ether extraction were separately adopted to extract the volatile oil from Curcuma.β-elemene of each volatile oil was assessed by GC,and their contents were compared with each other.[Results]The content of β-elemene in the steam-distilled volatile oil is significantly higher than that in the petroleum ether-extracted one.[Conclusion]The method of steam distillation for extracting the volatile oil from Curcuma is better than the method of petroleum ether extraction.
