| Abstract: | 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. |
