“…On basis of the characteristics of alkalescence and lipophilic molecules, various solvents were applied to the extraction of macrolide compounds. The common solvents such as methanol (Wu et al, 2013), acetonitrile (Błądek, Posyniak, Gajda, Gbylik, & Żmudzki, 2012), Tris buffer (Dubois, Fluchard, Sior, & Delahaut, 2001), phosphate buffer solution (García-Mayor, Garcinuño, Fernández-Hernando, & Durand-Alegría, 2006) or ethyl acetate (Wang et al, 2014) were reported. In this study, the extraction efficiency of three extraction solvents including methanol, acetonitrile and ethyl acetate was compared.…”
