AbstractPudilan Xiaoyan Oral Liquid has been widely used in the clinical treatment of inflammatory diseases such as upper respiratory tract infections. Taraxaci Herba, as the monarch medicine in Pudilan Xiaoyan Oral Liquid, due to its multi-source, multi-origin characteristics, and the difference in the content of active ingredients in different medicinal parts, has become a potential factor for the unstable quality among different batches of Pudilan Xiaoyan Oral Liquid. In this paper, Thermo Scientific Vanquish ultra-high-performance liquid chromatography(UPLC) system was used, and the Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System(2012 Edition) issued by National Pharmacopoeia Commission was used for processing and analysis. The main common peaks were identified and contents were determined by comparison with reference substances. Fingerprints of Taraxaci Herba medicinal materials from different origins were established. 13 common peaks were identified, and 29 batches of samples from five origins had similarities above 0.90. At the same time, an ultra-high performance liquid chromatography method was developed for the determination of monocaffeoyl tartaric acid, chlorogenic acid, caffeic acid, chicoic acid, and luteolin in Taraxaci Herba. The quantitative analysis conditions were verified by methodology, and the average sample recovery was 97.30%-101.8%. The results showed that the content of the same ingredient in Taraxaci Herba from different origins and different medicinal parts was obviously different, and the fluctua-tion range was also different for different ingredients. The establishment of UPLC fingerprints for Taraxaci Herba from different regions combined with multi-component content determination methods provides a reference for improving the quality control of Taraxaci Herba medicinal materials, and also provides a source guarantee for the quality improvement of Pudilan Xiaoyan Oral Liquid.
