Abstract A rapid, selective and sensitive UPLC-MS-MS assay was established to determine the plasma concentrations of four steroidal saponins. Sprague-Dawley rats were allocated to four groups which were orally administered Anemarrhena asphodeloides extracts ASE, ASE combined with macromolecular fraction ASE-MF, ASE combined with small molecule fraction ASE-SF and ASE combined with small molecule and macromolecular fraction ASE-SF-MF containing approximately the same dose of ASE. At different time points, the concentration of timosaponin BII, anemarsaponin BIII, timosaponin AIII and timosaponin E1 in rat plasma were determined and main pharmacokinetic parameters including Cmax, Tmax, T1-2, AUC were calculated using the DAS 3.2 software package. The statistical analysis was performed using the Student’s t-test with p < 0.05 as the level of significance. MF had no effect on the pharmacokinetic behaviors and parameters of four steroidal saponins. It was found that Cmax and AUC of four steroidal saponins in group ASE-SF and ASE-SF-MF, were significantly increased compared with those in group ASE. These results indicate that SF in A. asphodeloides extracts could increase the absorption and improve the bioavailability of the steroidal saponins. View Full-Text
