摘要
优选玉米须总黄酮的最佳提取工艺。采用L9(34)正交实验,对影响因素提取温度、乙醇浓度、料液比和提取时间进行优化,以总黄酮含量为评价指标,并采用分光光度法测定含量。玉米须总黄酮的最佳提取工艺为加入药材量30倍50%乙醇在60℃下超声提取10 min。优选得到的工艺稳定可行。
To optimize the extraction process of the total flavone in Zea mays. L. The extraction tempera-ture, alcohol content,material liquid ratio and extraction time were optimumed by L9 （34） orthogonal design, where the content of the total flavone was defined as the standard index. The total flavone was deter-mined by speetrophotometry. The restdts show that the optimal extraction process is that the raw powder of Zea mays. L. is combined with 30 folds volume of 50% alcohol solvent, the temperature is 60℃ and the extraction time is 10 min. The optimized process is stable and available.
