摘要
提取黑果腺肋花楸中黄酮类化合物并进行含量测定.采用超声波辅助提取方法,利用单因素结合正交实验进行提取并优化工艺.结果表明,最佳提取条件为:乙醇浓度为40%,料液比1∶25,提取时间25 min,在此条件下黑果腺肋花楸黄酮得率为0.166%,影响黑果腺肋花楸黄酮得率的因素依次为料液比、乙醇浓度、提取时间.
The single factor and orthogonal experiment were used to optimize the ultrasonic extraction of flavonoids from Aronia melanocarpa.The results showed that the optimal extraction parameters were obtained as follows:ethanol concentration,40%;material to liquid ratio,1∶25,extraction time,25 min.Under these conditions the yield of flavonoids was 0.166% and the affected factors to flavonoids in Aronia melanocarpa were material to liquid ratio,ethanol concentration,extraction time.
