Aims: Based on the gut microbiota and plasma metabolites, the underlying mechanism was analysed for the anti-hepatocellular carcinoma (HCC) effects of Ganfule capsule (GFL) in the study. Methods and results: The UPLC-Q-TOF/MS results showed that 13 key compounds were identified in GFL and the major active ingredients included amygdalin, saikosaponin A, astragaloside I, etc. The nude mice received HepG2 injection, and GFL showed lower volume and weight of the tumour. In addition, the apoptosis proteins (Bax and Bcl2) were altered in response to ...
