摘要
目的对不同产地覆盆子所含的微量元素进行比较。方法采用电感耦合等离子体质谱仪对10个产地覆盆子所含的27种微量元素[钾(K)、钠(Na)、钙(Ca)、镁(Mg)、铁(Fe)、锶(Sr)、银(Ag)、铝(Al)、砷(As)、钡(Ba)、铍(Be)、镉(Cd)、钴(Co)、铬(Cr)、铜(Cu)、锰(Mn)、钼(Mo)、镍(Ni)、铅(Pb)、锑(Sb)、硒(Se)、钍(Th)、铊(Tl)、铀(U)、钒(V)、锌(Zn)和汞(Hg)]进行含量测定。结果10个产地的覆盆子中均含有丰富的对人体有益的微量元素,重金属元素含量均未超标,比较而言,其中Mn是浙江千岛湖、皖南歙县和皖南绩溪产覆盆子中富集较多的元素,也是差异性元素,所含22种(K、Na、Ca、Mg、Fe、Zn、Cu、Mn、Co、Ni、Pb、As、Cr、Cd、Se、Mo、Sb、Sr、Hg、Ag、Al和V)对人体有益的微量元素中,9种(K、Na、Mg、Zn、Cu、Cd、Mn、Sr和Al)含量也高于其他产地,8种(Ca、Fe、Co、Ni、Cr、Se、Mo和V)含量次之。结论不同产地覆盆子药材中的微量元素含量存在地域性差异,为覆盆子的质量评价与道地性研究提供依据。
Objective To compare trace elements in Rubi Fructus medicinal materials from different origins.Methods Microwave digestion and ICP-MS were used for the content determination of 27 trace elements(K,Na,Ca,Mg,Fe,Sr,Ag,Al,As,Ba,Be,Cd,Co,Cr,Cu,Mn,Mo,Ni,Pb,Sb,Se,Th,Tl,U,V,Zn and Hg)in Rubi Fructus from 10 habitats.Results Rubi Fructus from 10 producing areas was rich in trace elements that are beneficial to human health,and the content of heavy metal elements did not exceed the standard.Comparatively speaking,manganese was enriched in Rubi Fructus samples from Qiandao Lake in Zhejiang province,Shexian County in Southern Anhui and Jixi in Southern Anhui.Manganese was also a differential element.Among the 22 trace elements(K,Na,Ca,Mg,Fe,Zn,Cu,Mn,Co,Ni,Pb,As,Cr,Cd,Se,Mo,Sb,Sr,Hg,Ag,Al and V)that are beneficial to the human health,the content of 9 types(K,Na,Mg,Zn,Cu,Cd,Mn,Sr and Al)was also higher than that of other producing areas,and the content of 8 types(Ca,Fe,Co,Ni,Cr,Se,Mo and V)was the second.Conclusion There are regional differences in the content of trace elements in Rubi Fructus medicinal materials from different origins,which provides a basis for quality evaluation and authentic research of Rubi Fructus.
