| Abstract: | Extraction of the soybean isoflavone was studied by combination method of microwave and light wave radiation without solvent.We discovered that only using 9.4% N,N-dimethyl formamide DMF as the energy transfer medium,heating the sample for 6min with power 800W(microwave 55% and light wave 45%),the total flavanone was extracted with ethyl alcohol.The extraction rate of daidzein that was 0.14%,closed with the corresponding conventional extraction process.This method had many merits,such as simplicity of operator,rapid,low cost,small environmental pollution and so on.Extraction mechanism was investigated preliminarily with high magnification fluorescence microscope FM,IR.It indicated that the improvement of extraction efficiency of secondary metabolite was possibly because the plant tissue structure was changed by microwave. |
