无患子总皂苷的提取分离

摘要：本课题尝试采用水提方法分离纯化无患子皂苷。利用单一变量法改变单一的实验变量进行实验，对不同目数无患子粉末运用单一变量法通过控制目数、物料比、时间、搅拌速度、温度、浸提次数进行实验从而得到各个水提的无患子皂苷样液。对得到的各组样液进行吸光度测定，通过分析其吸光度来判断无患子皂苷的得率、纯度等。探讨不同的实验条件对无患子皂苷得率的影响：如目数、物料比、时间、搅拌速度、温度、浸提次数等。通过对各个实验条件变量的优化得出最佳水提条件通过实验研究表明，当温度为60℃，物料比为1:8，时间为,3h，目数80目，转速为800转，浸提次数为3次时皂苷得率比较高。研究内容对皂苷提取方式研究、天然产物的开发利用以及环境保护、资源节约等方面具有积极意义。32228

The extraction and separation of sapindus saponins
Abstract:This paper attempts to separation and purification by water extraction method Sapindus saponins. Using a single variable method to change a single experiment experimental variables, different number of Sapindaceae powder method using a single variable by controlling mesh material ratio, time, stirring speed, temperature, extraction times for each experiment in order to get the water to mention Sapindus saponins sample solution. For each set of samples was measured absorbance obtained by analyzing the absorbance to determine Sapindus saponin yield, purity and so on. Explore the different experimental conditions on Sapindus saponins yield: such mesh material ratio, time, stirring speed, temperature, extraction times and so on. By optimizing each experimental condition variable optimum conditions for water extraction by experimental studies have shown that when the temperature of the material ratio of time for the purpose of extracting the number of times the speed is too high saponin yield research to promote new separation technologies terms of use industrialization, development and utilization of natural products as well as environmental protection has a positive meaning.
