Study on the Extraction Technology of Flavonoids from Gynura bicolor (Roxb.ex Willd.) DC.
摘要
Abstract
Flavonoid is a kind of natural physiological active substance,and it is an important raw material for the development of functional food.In order to explore the optimum extraction conditions of Flavonoids from Gynura bicolor (Roxb.ex Willd.) DC.,the factors affecting the extraction effect were studied,and the extraction process parameters were optimized by orthogonal test.The results show that the effect of G.bicolor (Roxb.ex Willd.) DC.flavonoids extraction sequence of various factors for the effect of extraction temperature,ethanol concentration,extraction time and solid-liquid ratio.optimum extraction conditions of Flavonoids from G.bicolor (Roxb.ex Willd.) DC.Were extract liquid material ratio 25 ∶ 1,60％ ethanol concentration,extraction temperature of70℃,time 1.5h.the flavonoids content in dry G.bicolor (Roxb.ex Willd.) DC.under optimal extract conditions was 72.136 mg/g.The results of this study provide a scientific basis for the nutritional evaluation of Wild vegetable and the development of functional food.关键词
