摘要
目的:考察大蓟不同炮制品中微量元素含量的变化。方法采用微波消解样品,结合电感耦合等离子体发射光谱(ICP-OES)法对大蓟10种炮制品中Na、Mg、K、Ca、Mn、Fe、Cu、Zn 8种微量元素含量进行了测定。结果大蓟不同炮制品中,Ca、K、Fe、Mg的含量明显大于Na、Mn、Cu、Zn含量,其中,以Ca、K含量最为显著;大蓟经炒制后,微量元素含量均比大蓟生品含量高;Ca、K、Mn、Zn、Na在不同炮制品中的变化范围较大,分别是生品Ca、K、Mn、Zn、Na含量的0.99~2倍、1.01~2.37倍、1.07~2.29倍、1.07~1.87倍、1.07~3.66倍。结论大蓟炒炭后微量元素有较大变化与其炒炭后止血药效增强有一定的关系。
Objective Toobservethechangesofthetraceelementlevelsindifferentprocessed productsofCirsiumjaponicumDC.Methods ThesamplesweredigestedbymicrowaveandICP-OPESwas applied to determine the levels of Na,Mg,K,Ca,Mn,Fe,Cu and Zn in 10 different produces of Cirsium ja-ponicumDC.Results IndifferentproducesofCirsiumjaponicumDC.,thelevelsofCa,K,FeandMawere higher apparently than those of Na,Mn,Cu and Zn.Of them,the levels of Ca and K were the highest signifi-cantly.After the baked and fried processing,the levels of trace elements were higher than those in the raw product.In different processed products,the levels of Ca,K,Mn,Zn and Na greatly changed and they were 0.99 to 2 times,1.01 to 2.37 times,1.07 to 2.29 times,1.07 to 1.87 times and 1.07 to 3.66 times as same asthoseofrawproductseparately.Conclusion Aftercharcoaled,thelevelsoftraceelementsofCirsiumja-ponicum DC.greatly change,which is related to the enhanced hemostatic efficacy after carbonization.
