马黛茶多酚的提取工艺研究

Research of the Extraction Process of Mate Tea Polyphenols

采用回流抽提法对马黛茶中多酚进行提取,并对其纯化工艺进行研究,依据单因素试验及正交试验的结果,表明最佳提取工艺条件为:乙醇(V/V)70%,回流温度为80℃,回流时间60 min,料液比为1∶9。

By reflux extraction to extract polyphenols in Mate tea, and the purification process were studied, based on the result of orthogonal experiment, showed that the best extraction conditions was: 70% ethanol, circumfluence temperature was 80 ℃, reflux time was 60 min, and solid-liquid ratio was 1 ∶ 9.
