超临界CO₂提取的百合挥发油化学成分的GC-MS分析

摘要: 目的研究百合挥发油化学成分。方法采用超临界CO₂提取方法，GC-MS联用技术鉴定百合挥发油成分，并用峰面积归一化法测定各成分的相对百分含量。结果超临界CO₂流体萃取法提取的挥发油共鉴定出50种成分，占挥发油总成分的72.96%。结论超临界提取百合挥发油成分多、效率高，与水蒸气蒸馏提取出的挥发油成分有差异。

Abstract: OBJECTIVE To research the volatile oil from Lilii Bulbus. METHODS The volatile oil from Lilii Bulbus was extracted by supercritical-CO₂ fluid extraction(SFE) and identified by GC-MS. The relative percentage content of components was determined by the area normalization method. RESULTS 50 components of Lilii Bulbus had been identified by SFE, which accounted for above 72.96% of the total volatile oil. CONCLUSION The volatile oil by SFE had many components and high efficiency. There were differences between SPE and steam distillation.
