阴香果实花色苷粗提物树脂纯化研究

阴香花色苷粗提物石油醚除脂后，以大孔吸附树脂DA201、DM301、DS401、D101 和 DM-18 进行了纯化技术的研究。静态吸附实验结果表明：DM-18 对阴香花色苷的吸附力最强，吸附量57.93mg/g，静态吸附平衡时间120min，80% 乙醇溶液的解吸率88.47%。DM-18 吸附花色苷动态解吸参数正交试验结果是：70% 乙醇最适洗脱剂、流速0.75BV/h 及pH3.0。

Purification of Crude Anthocyanins from Cinnamoumum burmanu Fruits Using Macroporous Resins

This study was conducted to develop a macroporous resin adsorption technique for the purification of crude anthocyanins from C. burmannii fruits. Following petroleum ether defatting, the crude anthocyanins were subjected to purification using different types of macroporous resins, such as DA201, DM301, DS401, D101 and DM-18. Static adsorption assays showed that DM-18 had the highest adsorption capacity towards anthocyanins of up to 57.93 mg/g with 120 min equilibrium adsorption time and 88.47% of anthocyanins were desorbed using 80% ethanol solution. Orthogonal array optimization suggested that the optimal conditions for desorption of anthocyanins from DM-18 were using 70% ethanol solution as desorption agent, flow rate 0.75 BV/h and pH 3.0.
