摘要
[目的]比较不同溶媒对葛根提取物中有效成分葛根总异黄酮、葛根素含量的影响。[方法]采用紫外及反相高效液相色谱法进行测定。[结果]不同溶媒葛根提取物中,葛根总异黄酮,葛根素的含量不同。其中,以60%乙醇提取物中总异黄酮的含量较高,达46%;丙酮提取物中葛根素的含量较高,达0.32%。[结论]5种溶媒葛根提取物中葛根总异黄酮,葛根素的含量各不相同,且以60%乙醇,丙酮提取效果较好。
[Objective ] The paper was conducted to compare the contents of isoflavone and puerarin in Kudzu root extract with different solvents. [Method] The contents of isoflavone and puerarin were determined by UV spectrophotometry and RP-HPLC. [Result] The contents of isoflavone and puerarin from the Kudzu root extract with different solvents were different. The content of isoflavone was the highest in the 60% alcohol extract, and reached 46% ; the content of puerarin was the highest in acetone extract, and reached 0.32%. [ Conclusion ] The contents of isoflavone and puerarin extracted by five solvents were different, and 60% ethanol or acetone showed the best effect on the extraction of isoflavone and puerarin from Kudzu root.
