Analytical Method Details Information

ID	MS1
Title	GC-TOF-MS lipid fraction method
Instrument	MS1
Instrument Type
Ionization	EI
Ion Mode	Positive
Description	Frozen sample was homogenized using mill mixer with liquid nitrogen. Metabolites were extracted by MeOH/H2O/CHCl3. After liquid‐liquid distribution, upper (MeOH/H2O) layer is used as polar fraction and bottom (CHCl3) layer is used as lipid fraction. Ribitol and nonadecanoic acid methyl ester were used for internal standards of polar and lipid fractions. Lipid fraction was methoximated with CHCl3/NaOH/MeOH. After washing by water, CHCl3 layer was dried over by N2 gas. Metabolites were trimethylsilylated with n-Heptane/Pyridine/MSTFA. GC conditions: Agilent 6890N GC (Agilent), Carrier gas: He, MS conditions: Pegasus III TOF-MS system (Leco).
