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.
目的
以总皂苷、总酸枣仁皂苷A和B以及总黄酮为指标，优化酸枣仁的提取工艺。
方法
采用单因素试验和正交试验法，以乙醇浓度、乙醇用量、提取时间和提取次数为正交试验因素，各因素均设3个水平。
结果
乙醇浓度和提取次数对所有指标均有显著影响，其他因素应根据生产实际选择。
结论
最佳提取工艺为用8倍量60%乙醇溶液提取3次，每次1.5小时。
