摘要
目的:建立EDTA滴定法测定附子不同炮制品中钙元素的含量。方法:采用EDTA滴定法测定附子不同炮制品中药材及煎煮液中钙元素的含量和溶出率,并对该实验的实验条件进行选择。结果:附子不同炮制品中钙元素由高到低依次为:盐附子>黑顺片>白附片>生附子;溶出率由高到低依次为盐附子>白附片>黑顺片>生附子。结论:本方法简便快捷,为附子不同炮制品钙元素含量测定提供了研究依据。
Objective:To establish EDTA titration for determining the calcium content of Aconiti Lateralis Radix Praeparata and its processed products.Method:EDTA titration was applied to determine the calcium content and dissolution rate in crude drugs and aqueous solution of different Aconiti Lateralis Radix Praeparata processed products,and the experiment condition was selected.Result:The sequence of calcium content in different Aconiti Lateralis Radix Praeparata processed products was:yan fuzi>hei shunpian>bai fupian>sheng fuzi.And the sequence of dissolution rate was yanfuzi>baifupian>heishunpian>shengfuzi.Conclusion:This method is simple and convenient,and provides research evidence for determination of the calcium content in different Aconiti Lateralis Radix Praeparata processed products.
