i摘要采用水蒸气蒸馏法提取杨梅叶精油,在单因素试验的基础上,运用Minitab 16.0数据分析软件,设计3因素3水 平的响应面法优化杨梅叶精油的提取工艺条件,并利用GC/MS分析了杨梅叶精油的主要组成成分。优化结果表明,在 温度170°C ,料水质量比1:7,蒸馏时间为7 h的条件下,杨梅叶精油的提取得率达0.129%。GC/MS分析鉴定出杨梅叶精 油20种化学成分,占总峰面积的96.25%,其中荐草烯、石竹烯、氧化喇叭茶烯一(II)、y-雪松烯等主要成分-567%,并含 有微量的酯类、醇类、酮类和烷类等物质。 关键词 水蒸气蒸馏:精油:化学成分;响应面.

The Myrica rubra leaves oil was extracted by steam distillation. Based on the single factor experiment, by adopting the method of response surface analysis with three factors and three levels with Minitab 16.0 data analysis software, gas chromatography mass spectrum(GC/MS) was employed to analyze the major component of essential oils. According the above results, the optimal technical condition was as follows: the temperature of 170 °C, material-water mass ratio of 1:7, distillation time of 7 h. Under the condition, the Myrica rubra leaves essential oil extraction yield is 0.129%. The analysis of GC/MS showed that 20 kinds chemical composition of essential oils was identified, which was 96.25% of GC total peak area. The humulene, caryophyllene oxide, ledene oxide-(II) and γ-himachalene accounted for 67% and trace amounts of esters, alcohols, ketones and alkanes other substances was found.
