Abstract:
In order to optimize the extraction process of total flavones,based on single factor experiments the effects of ethanol concentration,extraction temperature,extraction time and solid liquid ratio on the extraction of total flavones from E.ciliata Thunb.were studied by orthogonal experiment,with the extraction rate of total flavones as the investigation index.The results showed that the influencing order of each factor on the extraction of flavones was as follows：extraction temperature>ethanol concentration>extraction time>solidliquid ratio.The best ultrasonic extraction parameters were as follows：ethanol concentration was 55%,extraction temperature was 90℃,extraction time was 90 min,solid liquid ratio of 1∶35.Under this condition,the extraction yield of total flavones could reach 2460 mg/g DW.The research results provided theoretical basis for the industrialized production of total flavones from E.ciliata Thunb..
