摘要
用微波消解及火焰原子吸收法测定5月,6月,8月,9月及10月等5个时期的桑叶中Fe,Mn,Cu,Zn,Ca5种元素的含量,同时做精密度和加标回收试验,并对其含量进行比较,以期为临床,药物及食用含量研究开发利用提供参考。测定结果表明,各元素总体含量Ca>Fe>Mn>Zn>Cu,不同时期桑叶中微量元素各不相同,9月的桑叶中,各元素的含量均较高。
Trace elements in mulberry leaves in different months were determined by flame atomic emission spectrometry with digestion of microwave. Five trace elements Fe, Mn,Cu,Zn and Ca were determined separately in several different months as Ca〉Fe〉Mn〉Zn〉Cu in mulberry leaves. Each trace element in September is higher than thosein other months, which offers some useful information for the study of chemical medicine, pharmacy and food.
