HPLC-Fingerprint of Qinghai genuine medicinal herb——Gentiana straminea / 中草药

Objective To establish the fingerprint of Gentiana straminea from Qinghai Province by HPLC. Methods By orthogonal design and related methods based on information theories and chemometrics to optimize the proper HPLC conditions so that the fingerprint spectra of ten groups of different samples have been formed. Results The experimental results are the fact that the common fingerprint peaks, precision, and repeatability in the fingerprint totally meet the relative regulations required in Technical Requirements of the Fingerprint Research in Injection of Chinese Materia Medica (Tentatine Standard). Conclusion The chromatographic fingerprint can be used to identify and evaluate the quality of G. straminea.
