Thin-layer chromatography detection method for radix pseudostellariae in ginseng-radix puerariae kidney-tonifying preparation

The invention relates to a thin-layer chromatography detection method for radix pseudostellariae in a radix pseudostellariae-radix puerariae kidney-tonifying preparation. The radix pseudostellariae-radix puerariae kidney-tonifying preparation is prepared from the following raw materials: radix pseudostellariae, radix puerariae and herba epimedii. The thin-layer chromatography detection method for radix pseudostellariae in the ginseng-radix puerariae kidney-tonifying preparation comprises the following steps: respectively preparing a test solution and a radix pseudostellariae reference medicinal material solution; dripping the test solution and the radix pseudostellariae reference medicinal material solution on the same thin layer chromatography plate, developing with a developing solvent, adding a color developing agent for color development, and inspecting; wherein the developing solvent is a mixed solvent composed of isopropanol with the volume fraction of 75% and ethyl alcohol according to the volume ratio
