OBJECTIVE To optimize the existing t hin layer chromatography （TLC）identification and content determination methods of Jizhi syrup. METHODS High performance thin-layer chromatography （HPTLC）was used to identify five medicinal materials in Jizhi syrup ，such as Ilex chinensis ，Houttuynia cordata ，Peucedanum praeruptorum ，Citrus aurantium ，Glycyrrhiza uralensis. High performance liquid chromatography （HPLC）was used to determine the contents of procatechuic acid ，ephedrine hydrochloride and naringin in Jizhi syrup. RESULTS HPTLC results showed that the identification spots of pedunculoside ， praeruptorin A ，naringin，and liquiritin were clearly displayed ，and the retention factors were in the range of 0.2 to 0.8. After validation，the method had been proved to be strongly specific ，robust and repeatable. HPLC results showed that the linear ranges of protocatechuic acid ，ephedrine hydrochloride and naringin were 4.32-431.67，1.14-114.17 and 7.02-702.33 μg/mL（all r＞ 0.996），respectively. The average recoveries were 100.61％，100.40％ and 99.22％，and RSDs were all less than 2.00％. RSDs of precision（n＝6），stability（24 h，n＝7）and repeatability （n＝6）were all less than 2.00％. The average contents of the three components in 10 batches were 623.3，152.1，1 213.9 μg/mL（RSD＜10.00％），respectively. CONCLUSIONS In this study ， HPTLC method of one-plate multi-drug is established for the identification of Jizhi syrup. One sample pretreatment method and two TLC conditions are used to realize the rapid identification of five kinds of medicinal materials. An HPLC method is established to determine the content of Jizhi syrup ，which realizes the fast quantification of three active components in Jizhi syrup ，and can be used to optimize the identification and content determination items in the existing legal quality standards of Jizhi syrup.
