Centroid mass spectra data for α-Tocopherol and its oxidative products separated by supercritical fluid extraction (SFE)/supercritical fluid chromatography (SFC)-proton transfer reaction (PTR) ionization time-of-flight (TOF) mass spectrometry.  SFE was carried out at 40°C 25 MPa of CO2.  One μL portion of extracts in the fluid was injected into an SFC system.  SFC was carried out at 40°C, 30 MPa of CO2, 1.0 mL/min isobaric using L-column3 (2.1 mm x 100 mm, 3μm).  The data file 'Not incubated (83.1)-0024-83.csv' and the 'Incubated (82.3 s)-82.3.csv' are both the mass spectrum of α-tocopherol obtained from non-incubated and incubated samples, respectively.   The number in a pair of parenthesis indicates the retention time for the data on an incubated α-tocopherol sample.
