ISTD raw abundances across the three extraction methods in (A) positive ion mode and (B) negative ion mode. The Alshehry method was as effective as the Folch and Matyash method in extracting most lipid classes and was more effective in extraction of more polar lipids (LPC, LPE and PI). Error bars represent SE (*p < 0.05 relative to single phase method). CE, cholesterol ester; D5DG, deuterated diacylglycerol; DG, diacylglycerol; LPC, lysophosphatidylcholine; LPE, lysophosphatidylethanolamine; PC, phosphatidylcholine; PE, phosphatidylethanolamine; PG, phosphatidylglycerol, PI, phosphatidylinositol, PS, phosphatidylserine, SM, sphingomyelin; TG, triacylglycerol.
