Representative mass spectra in ESI–MS analysis in the range of m/z 450–960 scanning mode for the detection of phospholipid species. a PL spectra represent lipid extract from one of ten aliquot quality control (QC); b PL spectra represent lipid extract from one of benign hepatic tissue (BHT) samples and c PL spectra represent lipid extract from one of hepatocellular carcinoma (HCC) samples; d correlation and regression analyses of mean concentrations in 13 PL classes between two quantitative methods. The plot showed a significantly linear correlation between mean concentrations of 13 PL classes in nmol/mg wet weight tissue (wwt) and that in nmol/mg protein (r2 = 0.9999, p < 0.0001)
