Sample Preparation:

Sampleprep ID:	SP002019
Sampleprep Summary:	The hydrophilic and hydrophobic compounds were extracted using methanol/water and MTBE/methanol/water solvent systems, respectively. Samples were first thawed on ice. To extract hydrophilic metabolites from the tissue samples, 1 ml of methanol/water (7:3, v/v) was added to 50 mg of the liver, and homogenized with steel balls for 3 min at 30 Hz, followed by 1 min of a vortex. The homogenate was then centrifuged at 12,000 rpm for 10 min at 4°C to collect the supernatant. Hydrophobic compounds were extracted from another 50 mg using a slightly modified protocol. Homogenization was done with 1 ml of MTBE/methanol (10:3, v/v) and 100 µl of water was mixed with the homogenate to extract before centrifugation. For the sera of PB and HPVB, 3 volumes (v/v) of methanol and a mixture of MTBE and methanol (10:3, v/v) were whirled with the serum samples for 3 min, followed by centrifugation at 12,000 rpm for 10 min at 4°C. All collected supernatants were dried and store at -80°C until LC-MS/MS analysis. Internal standards were dissolved in the solvents before extraction.
