`

`
`resolution IT-TOF mass spectrometer (Figure 11), PC-EPA/EPA eluted first at

`approximately 5.2 minutes and was measured at m/z 826.5338 (Figure 12). Since
`
`the theoretical mass of PC-EPA/EPA is 826.5386 (Δm = -6 ppm), the elemental
`
`composition of this phospholipid in the Fujita once-through extract was determined
`
`to be identical to that of PC-EPA/EPA. PC-EPA/DHA eluted next from the

`
`and was measured at m/z 852.5493 (Figure 12). Since the theoretical mass of PC-

`
`phospholipid in the Fujita hexane extract was determined to be identical to that of
`
`PC-EPA/DHA. PC-DHA/DHA eluted at a retention time of approximately 5.6 min
`
`(Figure 11) and was measured at m/z 878.5668 (Figure 12). Since the theoretical
`
`mass of PC-DHA/DHA is 878.5699 (Δm = -3 ppm), the elemental composition

`system at a retention time of approximately 5.4 minutes (Figure 17) and was
`
`measured at m/z 852.5518 (Figure 18). Since the theoretical mass of PC-EPA/DHA
`
`is 852.5543 (Δm = -3 ppm), the elemental composition of this phospholipid in the
`
`Beaudoin extract P0 was determined to be identical to that of PC-EPA/DHA. PC-
`
`DHA/DHA eluted at a retention time of approximately 5.6 min (Figure 17) and
`
`was measured at m/z 878.5672 (Figure 18). Since the theoretical mass of PC-
`
`DHA/DHA is 878.5699 (Δm = -3 ppm), the elemental composition was determined
`
`to be identical to that of PC-DHA/DHA. Furthermore, the Beaudoin extract P0 was
`
`spiked with a PC-DHA/DHA standard and reanalyzed using UHPLC-MS/MS
`
`(Figure 17). The standard coeluted with the phospholipid in the extract thereby

`
`P2 was carried out using positive ion electrospray UHPLC-MS/MS with collision-
`
`induced dissociation and selected reaction monitoring (SRM) on a triple
`
`quadrupole tandem mass spectrometer. The SRM transitions that were used for
`
`analysis were m/z 826 to m/z 184 for PC-EPA/EPA, m/z 852 to m/z 184 for PC-
`
`EPA/DHA, and m/z 878 to m/z 184 for PC-DHA/DHA. A chromatogram for this
`
`analysis is shown in Figure 25.

`
`79. Figures 26-28 below reflect the result of my analysis of “Beaudoin
`
`Extract SU0” received from Dr. Budge’s laboratory. As shown in the Figures,
`
`each of the following three Claimed Phospholipid species was detected in the
`
`extract: PC-DHA/DHA, PC-EPA/EPA, and PC-EPA/DHA. Using UHPLC-MS on
`
`the high resolution IT-TOF mass spectrometer (Figure 26), PC-EPA/EPA eluted
`
`first at approximately 3.9 minutes and was measured at m/z 826.5415 (Figure 27).
`
`Since the theoretical mass of PC-EPA/EPA is 826.5386 (Δm = 3 ppm), the
`
`elemental composition of this phospholipid in the Beaudoin extract SU0 was
`
`determined to be identical to that of PC-EPA/EPA. PC-EPA/DHA eluted next from
`
`the UHPLC-MS system at a retention time of approximately 4.1 minutes (Figure
`
`26) and was measured at m/z 852.5540 (Figure 27). Since the theoretical mass of
`
`PC-EPA/DHA is 852.5543 (Δm = 0 ppm), the elemental composition of this
`
`phospholipid in the Fujita hexane extract was determined to be identical to that of
`
`PC-EPA/DHA. PC-DHA/DHA eluted at a retention time of approximately 4.5 min
`
`(Figure 26) and was measured at m/z 878.5701 (Figure 27). Since the theoretical
`
`mass of PC-DHA/DHA is 878.5699 (Δm = 0 ppm), the elemental composition was
`
`determined to be identical to that of PC-DHA/DHA. Furthermore, the Beaudoin
`
`extract SU0 was spiked with a PC-DHA/DHA standard and reanalyzed using
`
`UHPLC-MS/MS (Figure 28). The standard coeluted with the phospholipid in the
`
`
`- 74 -
`
`0000074
`
`
`
`
`
`extract thereby identifying this phospholipid in the Beaudoin extract SU0 as PC-
`
`DHA/DHA.
