Abstract: In order to establish the quality detection method of Qingying oral liquid,Flos Lonicerae,Fructus Forsythiae,Rhizoma Coptidis,Radix Salviae Miltiorrhiae,Raidix Scrophulariae and Ophiopogon jɑponicus in the prescription were identified by TLC,and the method of HPLC for the determination of chlorogenic acid was studied.The results showed that the TLC identification was highly specific,the spot was clear,and there was no interference in negative sample.The concentration of chlorogenic acid had a good linear relationship with peak area in the range of 8 to 160 μg/mL.The average recovery rate was 97.86%,and the RSD was 1.2%.In conclusion,the detection method established in this study was simple,accurate,specific and reproducible,which could effectively test the quality of the Qingying oral liquid.
