摘 要:目的用正交试验法优选麻口皮子药总黄酮的提取工艺。方法以总黄酮提取量为评价指标,在确定醇浓度的基础上,选择浸提温度、料液比、浸提时间为考察因素,采用正交试验法L9(34)确定醇提取麻口皮子药中总黄酮的最佳工艺。结果最佳提取工艺条件为20倍量的60%乙醇80℃提取75 min,提取时间为显著影响因素。结论麻口皮子药总黄酮正交提取工艺的研究结果可靠。Objective To study the optimum extraction process of total flavonoids in cortex zanthoxyli. Methods The extraction of total flavonoids was choosen as the assessment index. Temperature ratio of solid-liquid and extraction time as the study factors, the optimum ethanol extraction process was selected with the orthogonal design. Results The optimum ethanol extraction conditions were as follows: 20 folds of 60% ethanol, extracting for 75 min, at 80 ℃. the extraction time was the predominant influencing factor. Conclusion This optimum extration process of total flavonoids in cortex zanthoxyli is reliable.
