摘 要: 采用微波辅助法提取香根净油,通过实验确定了最佳提取工艺条件。研究结果表明,最佳提取工艺条件为:提取液中乙醇体积分数为80%,固液比1∶10(g/mL),微波频率2450MHz,功率1190W,微波时间5min。最佳提取工艺条件下香根净油提取率为6.41%。 The applicability of microwave irradiation ethanol method to assist the extraction of essential oil in Vetiver is testified to be the best technology of extracting. The research suggests: volume fraction of ethanol 80%, the ratio of material to water 1 ; 10, microwave frequency 2450 MHz, power rating 1190 W, microwave time 5 min (the best extraction time); On the condition of the best technology of extracting, the extraction rate of essential oil in Vetiver is 6.41%.
