超声提取贯叶连翘中总黄酮和金丝桃素的工艺研究
Study on the ultrasonic extraction technology for the total flavonoids and hypericin f rom hypericum perforatum
摘要
Abstract
The article researched the best process conditions on simultaneous extraction of to-tal flavonoids and hypericin from hypericum perforatum .,and explored the method of etha-nol ultrasonic assisted extraction to study the influences of ethanol concentration ,solid-liquid ratio ,extraction temperature ,extraction time ,extraction times on the yield of total fla-vonoids and hypericin .Then the extraction process was optimized by the orthogonal experi-ments .The result of the experiment shows that the optimum process conditions for ethanol ultrasonic assisted extraction technology of the total flavonoids and hypericin from hyperi-cum perforatum are ethanol concentration of 70% ,solid-liquid ratio of 1∶25 ,ultrasonic ex-traction temperature 50 ℃ ,extraction time 60 min ,extracted 2 times and the yield of hyperi-cin and flavonoids are 70 .18 mg/g and 0 .178% respectively ,the optimized technology is quick and simple and can be used for theoretical basic .关键词
