Separation and purification of total alkaloids from the peels of Carya cathayensis Sarg. by macroporous adsorption resin(大孔吸附树脂分离纯化山核桃蒲壳总生物碱)
用经筛选的大孔树脂分离纯化山核桃蒲壳总生物碱.选择极性不同的D101、AB-8、NKA-9 3种大孔树脂,比较其对山核桃蒲壳中总生物碱的吸附率和解吸率的影响,筛选较优树脂,并以总生物碱的纯化倍数和固体得率为考察指标,探索纯化工艺.NKA-9大孔树脂对山核桃蒲壳总生物碱有较好的吸附和解吸效果；pH为7.0的山核桃蒲壳生物碱提取液经大孔树脂吸附后,依次用蒸馏水2BV、30%乙醇2BV、50%乙醇3BV洗脱,总生物碱富集在50%乙醇部分,纯化倍数达到3.173倍,固体物得率为34.78%.采用NKA-9大孔树脂可以较好地分离纯化山核桃蒲壳总生物碱....
