食用花卉中微量元素锌可溶性糖结合态的提取研究

Study on Soluble Carbohydrate Binding Speciality of Zn in Edible Flowers

采用醇提取法对3种食用花卉菊花、芙蓉花、金银花中微量元素锌的可溶性糖结合态进行提取、分离;进行了锌的可溶性糖类结合态的提取、分离条件的选择试验,并且使用原子吸收分光光度计测定了Zn的可溶性糖结合态含量。结果表明食用花卉中Zn可溶性糖结合态分布较多,三种食用花卉中Zn的可溶性糖类结合态的含量分布相对较固定,形态分布为13.4%～14.5%左右;这说明Zn的形态之间存在着一定的平衡关系。

In the paper the content and specific analysis for soluble carbohydrate binding speciality of trace elements zinc inthree edible flowers: Chrysanthemum、Cottonrose hibiscus and Honeysucker have been studied respectively by AAS. Theresults show that the content of soluble carbohydrate binding speciation of zinc in the edible flowers is higher.
