Identification of oleic and arachidonic acid in active fractions. (A) GC/MS selected ion monitoring for m/z 87 = R-CH2-CH2-COO-Me, the common ion for PUFA, of active and inactive fractions. Samples were treated with BSTFA to produce Me3Si derivatives before injection. (B) LC/MS/MS selected ion chromatogram of m/z 302 = M-H shows the presence of arachidonic acid in the active fraction, which co-elutes with authenticated standards.
