摘要:
 研究无机絮凝剂纯化杜仲叶水提液的优化工艺条件,以总黄酮和桃叶珊瑚甙的含量和质量为检测指标,通过对比3种絮凝剂:七水合硫酸亚铁(FeSO4·7H2O)、聚合硫酸铁(SPFS)、聚合氯化铝铁(PAFC)的絮凝效果,采用单因素试验方法确定最佳纯化条件,以期为杜仲叶有效成分的工业化利用提供理论参考。结果表明,在 pH8~9条件下,用0.20%溶液质量分数的七水合硫酸亚铁处理初次浸提液,絮凝效果最好。
Abstract:
 Water extract of Eucommia ulmoides leaves were purified with three different inorganic flocculants, including ferrous sulfate (FeSO4·7H2O), polymeric ferric sulfate, and polyaluminum ferric chloride. The active constituents, such asflavonoids and aucubin were used as criteria to examine the results of purification. Satisfactory flocculation results were achieved by using 0.2% FeSO4·7H2O at pH8-9 to treat the first time extract.
