离子交换纤维柱分离纯化辣椒碱类化合物

考察了ZB-2强碱性阴离子交换纤维柱分离纯化指天椒中的辣椒碱类化合物。通过对离子交换纤维吸附前后扫描电镜图分析,表明吸附上了物质,并由红外光谱图分析证实所吸附的物质为辣椒碱类化合物。考察了上柱液pH、质量浓度、流速、上样量与离子交换纤维吸附量的关系,讨论了解吸条件中乙醇体积分数、流速、用量与离子交换纤维解吸率的关系,确定了离子交换纤维柱分离纯化的最佳工艺参数,得到在该条件下辣椒碱类化合物的质量分数由4.5%提高到92.0%,同时收率达72.3%。结果表明,离子交换纤维柱能快速分离纯化辣椒碱类化合物。

Separation and Purification of Capsaicinoids by Ion Exchange Column

The ZB-2 alkali anion exchange fiber column separating and purifying capsaicinoids from capsicum was investigated.Through analyzing the SEM before and after the absorption of capsaicinoids by the ion exchange fiber,its absorptive ability was determined.The absorbed compound was capsaicinoids through analyzing the infrared spectrum.Then the relations among the pH,mass concentration,flow velocity and absorptive capacity were investigated.Furthermore,the relations among the ethanol volume score,flow velocity,e...
