| 摘 要： | 用超临界CO2流体萃取技术(SFE)萃取平阴玫瑰浸膏,用分子蒸馏技术(MD)进行精制,所得玫瑰精油呈淡黄色,质量标准达到FCC(2004),得率由传统水蒸气蒸馏法的0.03%提高到0.1%。超临界CO2流体萃取最佳工艺条件为:萃取压力25 MPa,温度50℃,CO2流量25 kg/h,萃取时间2.5 h;分子蒸馏温度为80~120℃;所得精油GC-MS分析,检测出63种成分,主体呈香成分为酯类物质,质量分数超过50%,相对分子质量主要集中在200~250。

| Abstract: | Pingyin rose was extracted with supercritical CO_2 fluid extraction and then refined with molecular distillation.The refined rose oil was flaxen and its quality attained FCC(2004).Compared with method of steam distillation,yield of rose oil increased from 0.03% to 0.1%.The optimal extraction conditions were determined as pressure 25 MPa,temperature 50 ℃,flow rate of CO_2 25 kg/h and extraction time 2.5 h.The temperature range of molecular distillation was 80～120 ℃.63 components in the rose oil were detected by GC-MS,the molecular weights of which are mainly in the range of 200～250,and the main aromatic components(about 50%) are esters. |
