Objective To establish the methods of thin-layer chromatography (TLC) identification, HPLC fingerprint and content determination (puerarin and verbascoside),and to provide reference for improving the quality control of Qizhu Capsules. Methods Rehmanniae Radix, Astragali Radix and Puerariae Lobatae Radix in Qizhu Capsules were identified by TLC. The fingerprint was established by HPLC. The quality evaluation of 15 batches of Qizhu Capsules was conducted by the combination of HPLC fingerprint and similarity software. The contents of puerarin and verbascoside in Qizhu Capsules were determined by HPLC. Results TLC has strong specificity and the spots were clear. A total of 15 common peaks in the fingerprint of Qizhu Capsules were calibrated, 11 of which were identified, including catalpol, cucurbitacin B, 3-hydroxypuerarin, atractylodin, atractylenolide I, puerarin, quercetin, 3-methoxypuerarin, mirificin, daidzein and luteolin. Each peak showed good separation. The similarity values of 15 batches of Qizhu Capsules were greater than 0.95. The linear relationship of puerarin and verbascoside was good (R2≥ 0.999 2),the average recoveries were 99.31% and 96.89%,the average content were 13.07 mg·g-1and 50.81 μg·g-1 respectively. Conclusion The established methods of TLC,HPLC fingerprint and content determination are stable and reliable. These methods can provide scientific basis for the quality control of Qizhu Capsules.
