[Objectives] To establish a sensitive and simple thin layer chromatography method of matrine in Zhukuqin granule. [Methods]With Zhukuqin granule as control medicinal materials,matrine as reference substance,we chose orthogonal test method,systematically investigated various factors affecting the thin layer chromatography,and selected the best thin layer chromatography conditions. [Results] We screened out the best thin layer chromatography of matrine in the Zhukuqin granule with chloroform as extraction solvent,solvent extraction and ultrasonic extraction as extraction method,toluene-acetone-ethyl acetate-ammonia solution( 2:3:4:0. 5) as developing agent,improvement of bismuth potassium iodide solution as color developing agent. [Conclusions] The separating degree of this method was high,it had good repeatability,and it could be used to control quality of Zhukuqin granule.
