摘要
目的对超临界CO_2流体萃取法和水蒸气蒸馏法提取黄连木嫩叶挥发油的化学成分进行比较分析。方法用超临界CO_2流体萃取法和水蒸气蒸馏法提取黄连木嫩叶挥发油,对其化学成分采用GC-MS分析。结果超临界CO_2流体萃取法与水蒸气蒸馏法得到的挥发油成分具有一定差异,分别鉴定出18种和24种化学组分。其中8种为相同的主要挥发油成分,如β-月桂烯、D-柠檬烯、1-碘代-十六烷等。结论两种方法提取的黄连木嫩叶挥发油成分种类存在一定差异,但是主要挥发油成分的提取效果相当,综合考虑需要组分可以选择合适的提取方法。
Objective To make a comparative analysis of volatile oil constituents extracted from tender leaf of Pistacia chinensis Bunge with supercritical CO2 extraction and steam distillation. Methods The supercritical CO2 extraction and steam distillation methods were used to extract the volatile oil from tender leaf of Pistacia chinensis Bunge and their constituents were determined by GC-MS. Results The constituents extracted by supercritical CO2 extracts and steam distillation showed obvious difference, 18 and 24 kinds of volatile oil were determined, repectively. The result concluded 8 kinds of main volatile oil, such as β-myrcene, D-Limonene, 1-Iodohexadecane. Conclusion The methods showed similar results on extrating of main constutents from tender leaf of Pistacia chinensis Bunge, but also existting some differences on the kinds of volatile oil. So we can take the best extraction method into consideration obeying our needs.
