To investigate the metabolites of Periploca forrestii in plasma, urine, and feces of normal and adjuvant arthritis(AA) rats, and explore the effect of rheumatoid arthritis(RA) on the metabolism of active components of P. forrestii.
AA rat model was made by means of Freund’s complete adjuvant. Plasma, urine and feces of normal and AA rats were analyzed by UPLC-Q-TOF-MSE method using ACQUITY UPLC BEH C18 (100 mm×2.1 mm, 1.7 μm) column with 0.01% formic acid water -0.01% formic acid acetonitrile as mobile phase gradient elution at a flow rate of 0.25 mL·min-1, and electrospray ion source under negative ion mode.
Two and three prototype components, 32 and 35 metabolites were detected in normal rats and AA model rats. The metabolic pathways mainly include monocaffeoylquinic acid reduction, methylation, ring-opening cleavage, glucuronidation, dicaffeoylquinic acid reduction, methylation, acetylation, isomerization, sulfation glucuronidation, etc.
The metabolites in plasma and urine of AA model rats are more diverse than those in normal rats, and the disease state of RA may affect the metabolic pathway of effective components of P. forrestii in the body.
