Abstract
To observe the effect of total saponins of Clematidis Radix et Rhizoma (TSCR) on serum metabolic profile changes in adjuvant arthritis(AA) rats, and explore its possible action mechanism for AA rats. The AA rat models were induced by Freund's complete adjuvant(FCA), and their histopathological changes were observed. Gas chromatography-time-of-flight mass spectrometry (GC-TOF-MS), principal component analysis(PCA) and partial least squares-discriminant analysis (PLS-DA) were employed to analyze the metabolic profile among normal group, AA model group and TSCR group. Potential biomarkers in the serum were screened based on the variable importance projection(VIP) value>1, P<0.05. As compared with the normal group, 17 potential biomarkers such as aspartic acid, inositol and phenylacetaldehyde were found and identified in the serum of model group rats. As compared with the model group, the above biomarkers were regulated nearly to a normal state after TSCR administration for 16 days. Metabolomic analysis revealed that the total saponins of Clematidis Radix et Rhizoma has a certain therapeutic effect for AA rats, and the mechanism may be related to regulation of lipid metabolism, amino acid metabolism and energy metabolism.
