| Abstract: | Orthogonal design was used to optimize the ultrasonic extraction conditions of gingko flavonoid glycosides.The optimum extraction conditions were as follows:the raw materials of 1g,the extraction solvent of 60% ethanol,pH of 4.5,the extraction time of 40 min and the extraction temperature of 50℃.The average extraction rate of flavonoid glycosides was 81.83%.The extraction process is simple without any pollution,that is applied to preparing the gingko flavonoid glycosides in mass. |
