- 摘要:
- 以玉米须为试材，以乙醇溶液为提取剂，通过单因素和L9（34）正交实验，分别对乙醇的浓度、料液比、超声温度、超声时间4因素进行了优化组合，以总黄酮提取量为评价指标，研究了超声波辅助提取优选玉米须中的黄酮类物质的最佳工艺条件。结果表明：总黄酮类物质的最佳提取工艺为乙醇浓度40%，料液比1∶40 g/mL，超声温度60℃，超声时间5 min，此条件下黄酮提取率为0.301%。
- Abstract:
- With corn silk as material,the flavonoid extracted from corn silk was stuided by ultrasonic extraction,with the alcohol as extracting agent,the alcohol content,material liquid ratio,ultrasonic temperature and ultrasonic time were optimized by single factors and L9(34) orthogonal experiment.The flavone was defined as the amount of extraction.The results showed that the optimal extraction process of flavonoid was material liquid ratio 1∶40 g/mL,alcohol solvent 40%,ultrasonic temperature 60℃ for 5 min,the rate of extraction was 0.301% under this condition.
