Abstract:
In this study, ultra performance liquid chromatography-quadrupole-time of flight mass spectrometer-MSE (UPLC-Q-TOF-MSE) combined with UNIFI analysis platform was used to rapidly analyze and identify the metabolites of hederagenins 3-O-α-L-rhamnosyl-(1→2)-[β-D-glucopyranosyl-(1→4)]-α-L-arabopyranoside (Pulsatilla saponin D) and oleanolic acid 3-O-α-L-rhamnosyl-(1→2)-[β-D-glucopyranosyl-(1→4)]-α-L-arabopyranoside (Pulsatilla saponin B7) and hederagenins 3-O-α-L-rhamnosyl-(1→2)-α-L-arabopyranoside (Pulsatilla saponin BD) in plasma and colonic tissue of normal and ulcerative colitis (UC) rats. The database and analysis methods were established based on the precise molecular weight of compounds, retention time, neutral loss and reported data, and then the final data were obtained by comparing with the blank control group, combining with the deviation and the cracking rule of the compound. The results showed that the glucoses, hydroxylation and dehydroxylation, methylation and demethylation, dehydrogenation, decarboxylation and hydrolysis of saponin D, B7 and BD occurred in the plasma and colon tissues of normal and UC model rats. This study will clarify the metabolic transformation of Pulsatilla saponins D, B7 and BD in rats, determine the prototype components and their metabolites that enter the body, and whether colon injury will affect their metabolism in vivo, so as to explore the possible anti-colitis effective components in the prototype or metabolites of Pulsatilla saponins D, B7 and BD. This experiment was approved by Animal Ethics Committee of Jiangxi Science and Technology Normal University (approval number: Y202227).
