橙皮甙提取纯化工艺的优化

摘要

With orange peel as raw material,with 10 times of 7 g/L Ca( OH)2 as solvent soaking for 2 h,hesperidin was leached out with over 2. 9％ yield at pH = 5, recrystallization products with 98％ purity and 75％ yield. This method was convenient to operate, easy to control and its efficiency of extracting hesperidin was relatively high.%研究以Ca(OH)<,2>溶液做溶剂从橘皮中提取橙皮甙的工艺条件.得以桔皮为原料,,用10倍量7 g/L Ca(OH)<,2>,提取2h,提取液调pH=5,得率2.9%以上,重结晶得精制橙皮甙,纯度可达98%,收率为75%.此方法操作简便,易控制且提取橙皮苷的效率较高.
