Abstract

The invention discloses an identification method of Polygonum perfoliatum L. in a Kangfuling capsule. The identification method is thin layer chromatography utilizing a Polygonum perfoliatum L. contrast medicinal material, a caffeic acid contrast substance and a methanol-formic acid mixture with a ratio of 200-150: 1-2 as a developing solvent. The identification method utilizes a double contrast system comprising the Polygonum perfoliatum L. contrast medicinal material and caffeic acid contrast substance, has high controllability, operation simpleness, a high separation degree and good reappearance, prevents interference through a negative contrast and is not influenced by chromatography plates from different manufacturers and temperature and humidity conditions. The identification method realizes accurate, comprehensive, scientific and effective identification of Polygonum perfoliatum L. in a Kangfuling capsule, improves Kangfuling capsule quality detection standards and further ensures product quality stability and clinical drug use safety and effectiveness.
