摘要: 微波辅助萃取万寿菊残渣中的挥发油并分析化学成分。应用单因素试验和正交试验,研究液料比、萃取时间、微波萃取温度对万寿菊残渣中挥发油成分萃取效果的影响。结果确定最优化萃取条件为微波萃取温度为高温(700W)、萃取时间60s、液料比6:1(mL/g)、选用溶剂为石油醚,此条件下挥发油萃取率为1.575%;采用气相色谱-质谱对其化学成分进行分析,鉴定出19种有效成分。

Abstract: The microwave-assisted extraction of volatile oil from the residue left over after lutein extraction Tagetes erecta L. was optimized by one-factor-at-a-time and orthogonal array design methods. Oil yield was investigated with respect to solvent-to-material ratio, extraction time and microwave power (low, medium and high fire). The optimal extraction conditions were petroleum ether as the extraction solvent at a solvent-to-material ratio of 6:1 for 60 s extraction under the assistance of high-fire microwave power. Under the optimal extraction conditions, an oil yield of 1.575% was achieved. The chemical composition of the volatile oil was analyzed by gas chromatography-mass spectrometry (GC-MC) and 19 compounds were identified.

Key words: Tagetes erecta L., volatile oil, microwave extraction, gas chromatography-mass spectrometry
