范文编号:ZY093    范文字数:7037,页数:17

摘 要：油茶是山茶科植物属植物油,我国是世界上油茶籽产量最大、品种最多的国家。油茶籽饼中含有丰富的三萜皂甙。油茶皂甙是一种良好的表面活性剂，有较好的洗涤效果，耐高浓度电解质能力也较好，乳化、起泡、抗静电能力都比较强，可用于碳酸饮料的发泡剂、高级洗涤剂、灭火剂、乳化剂；油茶皂甙还有良好的药用价值，具有溶血、消炎、祛痰、抗真菌、抗突变的作用。本范文对从茶粉末中提取茶皂素的生产工艺进行研究，对影响茶皂素收率的因素进行了分析讨论，优化纯化提取工艺。并用高效液相色谱仪对茶皂素的含量进行定量分析。得含量为94%。

Abstract：Camellia is a vegetable oil, which is the world's largest varieties camellia oil in China. Triterpenoid Saponins is rich in camellia oil cake. Camellia Saponin is a good surfactant, a better washing effect of high concentrations of electrolyte resistance ability to better emulsification, foaming, anti-static capacity than the stronger of carbonated drinks can be used to foam, senior scullery agents, fire extinguishing agent, emulsifier，the medicinal value of Saponin are good with hemolytic, anti-inflammatory, expectorant, anti-fungal, anti-mutation effect. In this paper, study the production process of Tea Saponin extracting from the tea saponin, and discuss the impact of yield factors and optimize the extraction and purification. The quantitative analysis of Tea Saporin by reverse phase HPLC is taken．The results shown content is 94%.
Keywords：Camellia oil；Tea Saponin；Extract；HPLC
