Metabolites in MW and DM extracts from the mouse liver that were significantly different between the normal and UVB groups after 6 weeks and were tentatively identified using GC-TOF-MS analysis.

Variables were determined by using the VIP value (>0.7) and p-value (MW; MeOH/water extracts, DM; dichloromethane/MeOH extracts.atR was the retention time.bFold change was calculated by dividing the mean of the peak intensity of each metabolite from UVB group relative to the normal group.cVIP, variable important in the projection.dID, identification.eMetabolites were identified using commercial standard compounds (STD) in comparison with the mass spectra (MS) and retention time.*Saccharide was not successfully identified, but its mass fragments were similar to general mass fragments of saccharides.Metabolites in MW and DM extracts from the mouse liver that were significantly different between the normal and UVB groups after 6 weeks and were tentatively identified using GC-TOF-MS analysis.
