This study investigated the absorption profile of Wuwei Qingzhuo San in different intestinal segments and the absorption characteristics of its alkaloids(piperine, piperanine, piperlonguminine, and dihydropiperlonguminine). The everted gut sac model was established, and the chemical components of Wuwei Qingzhuo San in different intestinal segments were detected by UPLC-Q-TOF-MS. The content of piperine, piperanine, piperlonguminine, and dihydropiperlonguminine in intestinal absorption fluid was determined by UPLC-Q-TRAP-MS and the absorption parameters were calculated.

Objective: To investigate the effects of metformin (Met) on middle-aged male mice aging induced by D-galactose.

Methods: Fifty nine-month-old male ICR mice were fed in SPF experimental environment and fed freely with water. Subsequently, the mice were randomly divided into 5 groups(n=10): control group, model group, metformin low, medium and high dose groups(Met 50 mg/kg, Met 100 mg/kg, Met 200 mg/kg).
