摘要
Abstract
Elsholtzia flavone was extracted based on Elsholtzia oil meal by ultrasonic wave extraction, the content of Elsholtzia flavone was determinated by Colorimetry.The effect of single factor experiment by solvent concentration,liquid to solid ratio,extraction time,extraction temperature,and the extraction condi-tions on the extraction rate of flavonoids was investigated,the extraction conditions were optimized by orthogo-nal experiment.The experiment showed that the order affection of the extraction rate of flavonoids from Elsholtzia was:liquid to solid ratio >extraction time >extraction temperature >ethanol concentration;opti-mum conditions are:ethanol concentration of 60%,solid to liquid ratio of 1∶30,extraction temperature of 60℃,extraction time of 30min.Under these conditions,the extraction rate of flavonoids was 4.17%.The study would provide important guiding for the full use of the resources.关键词
