摘　　要：对丹参水煎液及人工胃酸提取液中的具有生物活性的微量元素Fe,Cu,Mn和Zn的形态进行了研究.用OasisTMHLB固相提取小柱、D401螯合树脂对2种丹参提取液中的Fe,Cu,Mn和Zn进行了提取.用AmberliteXAD-7大孔吸附树脂分离了丹酚酸等有机结合态,同时对蛋白质、多糖有机结合态分布进行了分析,用火焰原子吸收法(FAAS)测定了各形态微量元素的含量.结果表明:Zn和Cu的蛋白质结合态分布较高;多糖结合态中以Cu元素为主;XAD-7截留的丹酚酸等有机结合态中Fe元素的含量最高.The speciations of bioavailability trace elements including iron,manganese,copper and zinc in aqueous solution and artificial gastric acid solution of the Salviamiltiorrhiza were studied.The organic and inorganic,labile and stable forms were separated by Oasis TMHLB solid extraction minicolumn and D401 chelating resins.The resin XAD-7 was used for separating Salvianolic acid and other organic binding speciations.At the same time,the analysis of the distributon of protein and polysaccharide binding speciation of trace elements was done.All of the contents of the metal species above were determined by Flame atomic absorption spectrometry.The results showed that the content of protein binding speciation of Zn and Cu is higher than that of Fe and Mn,and the content of Cu is the most in the polysaccharide binding speciation,while Fe is the richest among the organically bonded elements retained on XAD-7 resin.
