摘要
目的研究射干中总黄酮的提取工艺。方法采用正交实验法进行优选,紫外分光光度法测定总黄酮的含量。结果乙醇用量和浓度对提取有显著性影响。结论最佳提取工艺为药材粒径<40目,加入药材6倍量70%乙醇,提取2次,每次提取1 h。
Objective To study the extraction process for the total flavonoids of Rhizorna Belameanda. Methods The optimum extraction process was selected with the orthogonal design. The content of total flavonoids was determined by UV-spectrophotometry. Results The effect of ethanol concentration and volume on the extraction of total flavonoids was significant. Conclusion The optimum extraction process is as follows： 6 times of 70% alcohol extraction twice, 1 h each time, with the diameter of drug powder less than 40 mesh.
