Study on the Microwave-assisted Extraction of Flavonoids from Hedyotis diffusa Willd
摘要
Abstract
[Objective] The study aimed to confirm the optimum technology condition for microwave-assisted extraction of flavonoids from Hedyo-tis diffusa Willd. [Method] With H. diffusa sold from Zhangzhou City of Fujian Province as the tested material,the effects of alcohol concn. ,microwave treating time and material-liquid rate on the extraction rate of flavonoids from H. diffusa were investigated through single factor test. And then,the technology condition for microwave-assisted extraction of flavonoids from H. diffusa was optimized by using L_9(3~3) orthogonal test. [Result] The single factor test showed that the optimum alcohol concn. was 60% , the optimum material-liquid rate was 1:30 and the optimum microwave extracting time was 60 s. The orthogonal test showed that the main factor affecting the extraction rate of flavonoids from H. diffusa was alcohol concn. ,followed by material-liquid rate and microwave treating time. Under the middle and lower grade of microwave power,the best extraction condition was follows: alcohol concn. of 60% ,extracting time of 80 s and material-liquid rate of 1:25. Under this condition,the extracting rate of flavonoids was 4.052%. [Conclusion] The microwave-assisted extraction technology could be used in rapidly analyzing the total content of flavonoids compounds from H. diffusa with simple operation.关键词
