Abstract

During the course of revaluation of tannin-bearing drugs, microanalytic method for gallotannins was followed in order to find their effect in human body, especially their change in the intestines. Satisfactory results were obtained by the modified Hagendorn-Jensen method, used in the determination of blood sugar, as well as with colorimetric method with ammonium molybdate.
