| Abstract: | The total flavones was extracted from persimmon leaves by microwave extraction method.The effects of ethanol mass concentration,microwave irradiation power,solid-liquid ratio(g∶mL) and microwave irradiation time on the extraction rate of total flavones from persimmon leaves were studied.The optimal extraction conditions were obtained by single factor experiment and orthogonal experiment as follows:ethanol mass concentration of 65%,solid-liquid ratio of 1∶25(g∶mL),microwave irradiation power of 300 W,microwave irradiation time of 15 min(extracting for 5 times,once for 3 min).Under above conditions,the extraction rate of total flavones was 5.22%.The total flavones was characterized by UV and FTIR.The method was efficient,for it cost less time and energy with high extraction rate. |
