| 摘 要： | 研究了汉中两个地区茯苓中的微量元素含量。湿法消解(HNO3)茯苓样品,火焰原子吸收光谱法测茯苓中的Ca、Mg、Na、Cu、Fe、Mn、K、Zn含量,石墨炉原子吸收光谱法测定茯苓中Pb、Cd二种重金属。茯苓中K含量最高,其次是Mg、Ca、Fe。除K外,汉中勉县茯苓中的微量元素含量普遍高于洋县。重金属测定结果表明,两地茯苓中重金属含量均未超出国家规定。本实验为进一步研究茯苓的药理活性提供了一定的基础。

| Abstract: | Trace elements of Ca,Mg,Na,Cu,Fe,Mn,K,Zn,Pb,Cd in Poria cocos in two regions of Hanzhong were determined by flame atomic absorption spectrometry with graphite furnace atomic absorption spectrometry and wet digestion(HNO3) method.The highest content of element is K,then Mg,Ca,Fe.The contents of trace elements are higher in Mianxian than in Yangxian of Hanzhong except K.The contents of heavy metals in Poria cocos do not exceed the national standard in both two regions.This experiment provides a certain founda... |
