摘要
目的:研究夜合花挥发油的化学成分。方法:利用水蒸气蒸馏法及超临界CO2萃取法提取桂产夜合花挥发油,用GC-MS联用技术对其化学成分进行分离鉴定,用面积归一化法确定各成分的相对含量。结果:水蒸气蒸馏法提取的挥发油鉴定56个化合物,占挥发油总量的87.46%,超临界CO2萃取法提取的挥发油鉴定25个化合物,占总量的95.86%。结论:桂产夜合花挥发油主要成分是α-蒎烯、橙花叔醇、石竹烯、吉玛烯D、双环吉玛烯,与文献报道其他产地的夜合花挥发油成分有明显差异。
Objective:To study the chemical constituents of the essential oils from Magnolia coco.Method:The essential oils were extracted by steam distillation(SD) and supercritical carbon dioxide extraction(SFE),and then the constituents were separated and identified by GC-MS.Result:Fifty six compounds were isolated and identified by SD that composed about 87.46% of the total essential oils;and 25 compounds were isolated and identified by SFE that composed about 95.86% of the total essential oils.Conclusion:The principal constituents of essential oils in M.coco from Guangxi are α-pinene,nerolidol,caryophyllene,germacrene D,bicyclogermacrene,which are very different from the other origin.
