[Objective] To study the method of qualitative and quantitative determination of tetramine in rats. [Method] The tetramine in samples was extracted by benzene or acetone, and qualitatively determined by sulfuric acid chromogenic acid or phenylhydrazine hydrochloride and sulfuric acid chromotropic acid method. [Results] The detection limit was 0.5 μg / 5 .0 ml, the linear range was 0.5-10 μg / 5.0 ml, the correlation coefficient was 0.9994, and the relative standard deviation (RSD) was 1.0-4.9% Yin and Yang ions do not interfere, the recovery rate of more than 95%. [Conclusion] The method is simple, rapid, accurate, sensitive, economical and practical, and it is an ideal tetramine detection method
