摘要(Abstract):

目的:分别以酸枣仁中总皂苷量、酸枣仁皂苷A,B总量、总黄酮量为检测指标对酸枣仁进行提取工艺优选。方法:采用单因素考察和正交试验相结合的方法,正交试验中以乙醇含量(A)、提取次数(B)、提取时间(C)、溶剂用量(D)4个因素,每个因素选取3个水平进行试验。结果:因素A,B对检测指标均有显著性影响,因素C,D为不显著因素,可结合生产实际进行选择。结论:以60%乙醇,8倍量提取3次,每次1.5h为最佳提取工艺。
Objective: To optimize extraction technology of the seed of Ziziphus jujuba var. spinosa with the targets of the total saponin, total jujuboside A and B and total flavonoids. Method: In the method of one-way and orthogonal tests, ethanol concentration, amount of ethanol, extraction time and extraction times were the factors in orthogonal test, and each factor with three levels. Result: Ethanol concentration and extraction times had significant effect on all the targets, other factors should be selected in accordance with production practice. Conclusion: The best extraction technology is to extract for three times with 8 fold ethanol solution(60%), and 1.5 h each time.
