摘要
以大豆豆荚为原料,以超声波法提取黄酮化合物。结果表明,豆荚黄酮的最佳提取工艺条件为:乙醇浓度70%,料液比1∶25(w/v)、萃取时间20 min、超声波功率270 W、浸提次数为3次。在此最佳工艺条件下进行试验,测得豆荚总黄酮得率为8.49%。豆荚总黄酮具有较强的体外抗氧化活性。
Soybean pods from Xu - kou farm in Suzhou were used as materials, ultrasonic extraction was applied to gain flavonoids from the soybean pods. Results show that the NaNO： - Al （NO3） 3 colorimetric method is proper to extract tlavonoids from soybean pods and the optimum conditions are as follows： use 70% ethonal as solvent with a solid/liquid ratio of 1 g 25 mL, at microwave power 270 W and extract for 20 min three times. On these conditions the yield of flavonoids can reach 8.49%. The produced flavonoids from soybean pods have strong antioxidation activity.
