Abstract: | objective] To study extraction technology of isoflavone from soybean by microwave assisted and ethanol extraction method.Method] Isoflavonoids were extracted from soybean with alcohol as extractant assisted by microwave.Based on single factor analysis and orthogonal test,alcohol concentration,solid-liquid ratio,microwave time,extraction temperature and extraction time were investigated on the effect of soybean isoflavone extraction amount.Result] The optimum extraction technology of isoflavone was as follows:alcohol concentration of 80%,solid to liquid ratio of 1∶ 16 g/ml,microwave time of 4 min,extraction temperature of 70 ℃ and extraction time of 2 hours.Under the condition,the extraction amount of soybean isoflavone was 25.37 mg(20 g defatted soybean powder).Conclusion] The extraction technology was simple and feasible with higher extraction amount. |
