    AbstractTaraxaci Herba was derived from the dried Herba of Taraxacum mongolicum, T. borealisinense and several species from the Taraxacum genus. Taraxaci Herba has been widely used in traditional Chinese and folk medicines. According to the different growth and cultivation pattern, Taraxaci Herba could be divided into two species, wild Taraxaci Herba and cultivated Taraxaci Herba. In the present study, an accurate and reliable fingerprint approach was developed using high performance liquid chromatography(HPLC) for quality control of Taraxaci Herba. A total of 9 common peaks were marked, and the similarity of all the Taraxaci Herba samples was above 0.960. The established fingerprint method could be used for quality control of Taraxaci Herba. Furthermore, an HPLC method was established for simultaneous determination of six bioactive compounds, including monocaffeoyl tartaric acid, chlorogenic acid, caffeic acid, cichoric acid, 4,5-dicaffeoylquinic acid and luteolin in wild Taraxaci Herba and cultivated Taraxaci Herba. Moreover,chemometrics analysis such as principal component analysis and orthogonal partial least squares discriminant analysis were performed to compare and discriminate the wild samples and cultivated samples based on the quantitative data. The chemometrics results indicated that 4,5-dicaffeoylquinic acid and luteolin were significant to effectively discriminate the wild Taraxaci Herba and cultivated Taraxaci Herba samples, and these two compounds could be recognized as chemical markers for quality evaluation of wild Taraxaci Herba and cultivated Taraxaci Herba. The fingerprint analysis and quantitative analysis of multi-components could be a well-acceptable strategy for evaluation the quality of Taraxaci Herba.Copyright© by the Chinese Pharmaceutical Association.
