Sampleprep Summary: | After vacuum freeze-drying, the biological sample was crushed at 30 Hz for 1.5 minutes using a mixer (MM 400, Retsch) with zirconia beads. One hundred milligrams of lyophilized powder was accurately weighed, dissolved in 1.2 ml of 70% methanol solution, rotated every 30 minutes for 30 seconds, repeated 6 times, and placed in a refrigerator at 4 °C for 12 h. Finally, after centrifuging the solution at 12 000 rpm for 10 minutes, the extract was filtered (SCAA-104, 0.22 μm pore size; ANPEL, Shanghai, China, http://www.anpel.com.cn/) to perform UPLC‒MS/MS analysis. |
