摘要: 采用NKA-9、AB-8和ADS-7 3种不同极性的大孔吸附树脂研究纯化茶黄素的工艺条件。比较大孔树脂的类型、pH值、上样速度、除杂液质量分数、样品洗脱液质量分数和体积对茶黄素纯度的影响,初步确定工业纯化茶黄素的工艺。结果表明,NKA-9的纯化效果明显优于AB-8和ADS-7,采用NKA-9纯化茶黄素的最佳工艺条件为:pH值为3,上样速度2BV/h,先用1BV 15%的乙醇除杂,再用3BV 90%的乙醇洗脱。纯化后茶黄素的纯度为44.1%。各单体纯化条件与上述纯化条件不尽相同,单体纯度与纯化条件密切相关。

Abstract: In order to purify theaflavins industrially, three macroporous adsorptive resins with different polarity such as NKA-9,AB-8 and ADS-7 were investigated and six factors as the type of resin, pH value, sample filling rate, effluent concentration of eliminating impurity, effluent concentration of sample and effluent volume of sample were determined. The result showsed that NKA-9 possessed a better purify effect than that of AB-8 and ADS-7, and the optimum condition is pH value of 3, sample filling rate of 2BV/h, 15% ethanol of eliminating impurity and 3BV 90% ethanol to elute. The purity of theaflavins can reach to 44.1% under this condition. But the purification condition had some difference between total mixture and each monomer.

Key words: macroporous adsorptive resins, theaflavins, purify
