Overview of the observed retention times in the HPLC chromatogram shown in Figure 1 and their assignment to the individual L. donovani phospholipid species.

alyso-PE, lyso-phosphatidylethanolamine; lyso-PC, lyso-phosphatidylcholine; PC, phosphatidylcholine; p-PC, plasmalogen phosphatidylcholine; IPC, inositolphosphorylceramide; PE, phosphatidylethanolamine; p-PE, plasmalogen phosphatidylethanolamine; PI, phosphatidylinositol; p-PI, plasmalogen phosphatidylinositol; CL, cardiolipin. The letter “a” denotes an alkyl-or alkenyl-ether residue in the plasmalogen species. In all cases only the most abundant fatty acyl compositions are indicated, while the detailed evaluation of very minor species was not the subject of this paper. The inositolphosphorylceramides are denoted as follows: IPC (long chain base/fatty acyl residue) with the prefixes “d” and “t” to designate di-and trihydroxy species.bRetention time of HPLC obtained from Figure 1.cPercentage within the given phospholipid class as determined from the MS-signal intensities. The fatty acyl compositions were assigned to the sn-1 and 2 positions by means of the differing signal intensities in the fragment ion spectra.
