摘要:

选用11种大孔树脂对藤茶黄酮进行了静态吸附与解吸附实验。结果表明,1号树脂适宜于藤茶黄酮的分离纯化,对黄酮的吸附量可达41.41mg/g,解析率达到89.5%。通过动态吸附实验对1号树脂有关参数进行了优化。结果表明,2.5×50cm层析柱,黄酮加样浓度7mg/ml,加样体积为50~60ml,流速1.8ml/min,用95%的乙醇进行洗脱,可达到较好的洗脱与纯化效果,黄酮的洗脱率可达90%左右,洗脱出的黄酮纯度达65%左右。进一步利用重结晶方法得到较纯的产品,经紫外可见光谱、红外光谱、HPLC-Ms分析表明,黄酮中的主要成分为二氢杨梅素。

Abstract:

The static adsorption and desorption properties among 11 kinds of macroporous adsorption resins to Ampelopsis grossedentata flavones were compared, respectively. The results showed that resin NO.1 is the best for the purification of flavones with an adsorption capability of 41.41 mg/g and a desorption rate of 89.5%. Furthermore, the dynamic adsorption and desorption process parameters of resin NO.1 were optimized. The results indicated that when the concentration of crude flavones is 7 mg/ml, the volume of sample is 50 to 60 ml on resin NO.1 column of 2.5 × 50 cm, the flow rate is 1.8 ml/min and the eluent is 95% ethanol, the elution rate of flavones is 90% and the purity of obtained flavones is about 65%. Finally, the above flavones product was further purified by means of recrystallization. The main composition of Ampelopsis grossedentata flavones is identified as dihydromyricetin via UV-Vis spectrum, IR spectrum, and LC-MS chromatography analysis.
