UPLC characteristic spectrum construction method and identification method for fructus malvae vertillatae

The invention relates to a UPLC characteristic spectrum construction method and an identification method for fructus malvae vertillatae. The UPLC characteristic spectrum construction method for the fructus malvae vertillatae comprises the following steps: (1) precisely weighing the fructus malvae vertillatae, and preparing a fructus malvae vertillatae test solution; and (2) analyzing the fructus malvae vertillatae test solution by using a UPLC to obtain a UPLC characteristic spectrum of the fructus malvae vertillatae. The method is relatively high in precision, stability and reproducibility; the identification method is rapid, accurate and objective; the chemical component characteristics of the fructus malvae vertillatae are fully displayed; the original content measurement of a few components is upgraded to the detection of the inherent quality of the whole drug; the defect of single chemical component inspection is avoided; the quality control of the fructus malvae vertillatae can be comprehensively and ac
