摘要
确定红凉伞和朱砂根不同部位铜、铁、锌、锰的含量。用硝酸、高氯酸混合酸消解样品,在对样品的处理和测定条件进行优化后,采用原子吸收光度法对红凉伞、朱砂根两种中药材的根、茎、叶、籽部位的铜、铁、锌、锰含量进行了测定,相关系数:0.99919~0.99981,加标回收率:94.8%~107.91%,相对标准差:0.4099%~1.7842%,测定结果令人满意。红凉伞的籽中铜、锌、铁含量均高于其它部位,锰含量叶中最高;朱砂根中铜、铁、锌、锰含量分别在籽、根、茎、叶中占据首位。从总体看,红凉伞朱砂根的叶和籽中微量元素含量比其它部位相对较高。测定结果为探讨该中草药各部位及变种间的药性的差异,充分利用红凉伞和朱砂根的叶、籽的价值提供了部分依据。
It was determined that the contents of Cu,Fe,Zn and Mn in different parts of Ardisia crenata Sims and Ardisia crenata Sims Var.bicolor(Walker).The samples were digested with HNO3-HClO4(4:1,V/V).After the optimum determination condition was sought,the contents of trace elements in root,caulis,leaf and fruit of samples were determined by flame atomic absorption spectrometry(FAAS).The standard relative coefficients of four kinds of trace elements range are from 0.99919 to 0.99981.The recovery rate of spiked sa...
