对牛蒡子中牛蒡子苷元微波辅助水解提取工艺进行了研究。采用微波法,利用单因素和正交实验对牛蒡子中牛蒡子苷水解提取牛蒡子苷元工艺进行了优化,并建立了牛蒡子中牛蒡子苷和牛蒡子苷元的高效液相色谱(HPLC)检测方法。结果表明,最佳水解工艺条件为:盐酸浓度1 mol/L、微波时间500 s、料液比1:6、水解一次,牛蒡子苷水解率达到98%以上,牛蒡子苷元提取率达到1.80%。与传统的水解提取方法比,本方法工艺简单、高效。
Microwave-assisted hydrolysis of arctigenin in Arctium lappa was studied. The microwave-assisted extraction of arctiin from arctiin was optimized by single factor and orthogonal experiments. The HPLC and HPLC )Detection method. The results showed that the optimum hydrolysis conditions were: hydrochloric acid concentration 1 mol / L, microwave time 500 s, solid-liquid ratio 1: 6, hydrolysis time, burdock fructose hydrolysis rate of more than 98%, arctigenin extraction rate of 1.80 %. Compared with the traditional hydrolysis extraction method, the method is simple and efficient.
