Sample Preparation:

Sampleprep ID:	SP001959
Sampleprep Summary:	Faecal samples were collected and immediately stored at -80 °C for further analysis. After the mice were sacrificed, liver tissue was sampled, immediately frozen in liquid nitrogen, and then stored at -80 °C. The study was approved by the Animal Ethics Committee of Saiye Biology (ACU20-A027). Mouse liver tissue (20 mg) and 600 μL CH3OH/H2O (8:2, vol/vol) solvent were combined in a centrifuge tube and then homogenized (28 Hz, 60 s and 30 s) in a frozen mixed ball grinding machine (MM400, Retsch Technology, Han, Germany). The mixture was centrifuged for 10 min at 15,000 g and 4 °C, 500 μL of supernatant was transferred to a new centrifuge tube for lyophilization, and the residue was reconstituted with 100 μL of Mix-IS-MeOH. Mouse faeces: A 60 mg sample of mouse faeces and 600 μL CH3OH/H2O (8:2, vol/vol) solvent were combined in a centrifuge tube and then homogenized (28 Hz, 60 s and 30 s) in a frozen mixed ball grinding machine (MM400, Retsch Technology, Han, Germany). The mixture was centrifuged for 10 min at 15,000 g and 4 °C; then, 500 μL of supernatant was transferred to a new centrifuge tube for lyophilization, and the residue was reconstituted with 100 μL of Mix-IS-MeOH.
