ABSTRACT
To compare the quality control indexes and chemical constituents of crude and wine-processed Dipsacus asper. According to Chinese Pharmacopoeia 2015 edition, water content, total ash, acid-insoluble ash and water soluble extract of different processed products were detected. UPLC-Q-TOF/MS approach was established to compare the contents of major constituents in crude and wine-processed D. asper. Moreover, the linearity, precision, stability, repeatability and recoveries of the approach were well studied. The results of water content, total ash, acid-insoluble ash and water-soluble extract of crude and wine-processed D. asper were all in line with the requirements of the Chinese Pharmacopoeia 2015 edition. Meanwhile, 20 main chemical constituents were identified by using UPLC-Q-TOF/MS. After wine-processing, the contents of asperosaponin Ⅵ, acetylate analogues and caffeic acid were significantly increased, while the contents of other phenolic components such as dicaffeoylquinic acid were decreased significantly, which may be which may be the main reason for different clinical efficacy of crude and wine-processed D. asper.
