摘要
采用无溶剂微波提取法(SFME)提取排草精油,单因素试验考察了排草的含水率、微波功率和萃取时间对精油得率的影响,建立了分析排草精油挥发性成分的气相色谱-质谱联用法(GC-MS)。结果表明:无溶剂微波提取排草精油的最佳条件是原料含水率为质量分数50%~60%,微波功率为500 W,萃取时间为60 min;最佳提取条件下,排草精油得率为2.19%。GC-MS分析结果显示,从排草精油中鉴定出75种挥发性成分,其中酚类和烯烃类化合物为主要成分,分别占总挥发性成分的28.53%和13.13%(相对质量分数)。排草精油的高效提取和精油挥发性成分的测定对排草香料资源的开发和利用具有重要意义。
In order to realize the rapid extraction and volatile components analysis of Lysimachus capillipes Hemsl.oil,a solvent-free microwave extraction(SFME)process was optimized.Single-factor experiment was conducted to investigate effects of water content,microwave power and extraction time on the yield of the essential oil.The volatile components of the essential oil were analyzed by gas chromatography-mass spectrometry(GC-MS).The results showed that the optimal extraction conditions of SFME were 50%-60%water content of the raw materials,500 W microwave power and 60 min extraction time,and the essential oil yield was 2.19%under the optimal extraction conditions.GC-MS analysis showed that 75 volatile components were identified from the essential oil,among which phenols and alkenes were the main components,accounting for 28.53%and 13.13%(relative mass fraction)of the total volatile components,respectively.The efficient extraction of the essential oil and the determination of volatile components in the essential are of great significance to the development and utilization of Lysimachus capillipes Hemsl.oil.
