ABSTRACT
ETHNOPHARMACOLOGICAL RELEVANCE The dispensing granules of traditional Chinese medicines (TCMs) is an innovative form of medicinal material for TCMs decoction, which is gradually recognized in the clinic due to being suitable for production on a large scale and convenient to take for patients. However, the quality control of TCMs dispensing granules is being challenged, because they contain too many unrevealed hydrophilic components. AIM OF THE STUDY Here, the dispensing granules produced from the rhizome of Atractylodes macrocephala (Baizhu dispensing granules), were explored as a case to explore the quality markers correlated to the clinical efficacy of TCMs dispensing granules by a comprehensive strategy of integrating chemical profiling, network pharmacology, and chemometric analysis. MATERIALS AND METHODS:
First, the chemical profiling of Baizhu dispensing granules was characterized by using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS). Subsequently, the potential active components responsible for the efficacy of Baizhu dispensing granules were screened via network pharmacology, and the ultra-performance liquid chromatography coupled with photodiode array detector (UPLC-PDA) method was developed for quantitative analysis of the potential active components in 26 batches of Baizhu dispensing granules. Finally, the quality markers of Baizhu dispensing granules were deciphered based on content variations of potential active components and chemometric analysis.RESULTS:
A total of 69 components were identified from Baizhu dispensing granules. Network pharmacology analysis further revealed that eight of them including five caffeoylquinic acids (31, 32, 36, 42, 44) and three sesquiterpenoids (63, 67, 76) were intimately connected to the core targets of dyspepsia, enteritis, gastritis and immunity. The contents of eight components differed greatly among 26 batches of Baizhu dispensing granules. Chlorogenic acid (31), cryptochlorogenic acid (32) and atractylenolide III (63) have higher concentrations and make great contributions to distinguish different batches of the Baizhu dispensing granules based on principal component analysis (PCA) and orthogonal partial least squares-discriminate analysis (OPLS-DA), and could be used as the quality markers of Baizhu dispensing granules.CONCLUSIONS:
Our study defined the quality markers of Baizhu dispensing granules, which will benefit further investigation on the quality evaluation of TCMs dispensing granules containing Baizhu. The strategy used in this study will be helpful for discovering the quality markers of other TCMs dispensing granules.Palabras clave
