Quality control method, quality control spectrogram and construction method of traditional Chinese medicine composition

The invention discloses a quality control method, a quality control spectrogram and a construction method of a traditional Chinese medicine composition. The traditional Chinese medicine composition isprepared from watermelon frost, calcined borax, cortex phellodendri, rhizoma coptidis, radix sophorae tonkinensis, rhizoma belamcandae, bulbus fritillariae thunbergii, indigo naturalis, borneol, soapberry fruits, radix et rhizoma rhei, radix scutellariae, radix glycyrrhizae and menthol. The quality control method comprises the following steps: simultaneously detecting cortex phellodendri, rhizomacoptidis, radix scutellariae, rhizoma belamcandae and liquorice root components in the traditional Chinese medicine composition by adopting an HPLC (High Performance Liquid Chromatography) method, wherein the HPLC method conditions are as follows: octadecylsilane chemically bonded silica is used as a filler; methanol is used as a mobile phase A, a 0.1% phosphoric acid solution is used as a mobilephase B, and gradient elut
