Abstract:Referring to the method in Europe Pharmacopoeia,a modified method for the determination of tannin in crude drugs was established. A tungsten molybdophosphate-casein colorimetric method was used with gallic acid as reference substance. Content of tannin in gallnut and radices sanguisorbae was tested. The average recovery rate was 97.39%. This method is reliable for the determination of tannin in crude drugs.
Keywords:tannin determination  colorimetric method
