咸宁桂花精油的前驱脂肪细胞生长和人体舒压试验的研究

本文采用超临界CO2流体法萃取三个品种咸宁桂花的干桂花得到其精油;采用石油醚浸提法浸提鲜桂花得到其浸膏,用气质联用分析了萃取桂花精油和浸膏的香气成分及其相对含量。进一步探讨了获得的精油对前驱脂肪细胞株3T3-L1细胞培养及生长的影响,并行人体神经舒压试验。结果发现其可减少细胞中的中性脂肪量;心电图LF和HF数据显示桂花精油具有一定的神经舒缓功效。

Studies on the Effect of the Osmanthus Fragrans in Xianning on the Growth of 3T3-L1 Preadipocyte and the Human Nervous Diastolic Pressure*

We extracted and got the essential oils from three varieties of dry Osmanthus fragrans in Xianning by supercritical CO2 fluid method;we extracted fresh O.fragrans by petroleum ether extraction method and got its extractum.Then we assayed by using GC-MS the fragrance ingredients and their relative content of extracted essential oils and extracts of sweet-scented O.fragrans.In this study,we performed the culture and growth experiments of 3T3-L1 preadipocyte with the O.fragrans essential oils,as well as the human nervous diastolic pressure test.Results showed the essential oils can reduce the amount of neutral fat.The data of electrocardiogram LF and HF showed the osmanthus essential oil has some nerve soothing effect.
