内容記述 |
Positive-ion electron impact (PIEI), positive-ion chemical ionization (PICI) and negative-ion chemical ionization (NICI) mass spectra of nifedipine, nisoldipine, nitrendipine. dehydronitrosonifedipine and dehydronitrosonisoldipine, were presented, and each fragment mode was analyzed. In the PIEI mode, molecular cations appeared in all compounds, though they were small. In the PICI mode, [M+1]+ quasi-molecular cations together with [M+C2H5]+ ions and many fragment ions, appeared. In the NICI mode. the number of peaks was much less than that in both positive modes; intense molecular anions were observed for nifedipine, nisoldipine and nitrendipine, which seem very useful for sensitive and specific detection by gas chromatography (GC)/mass spectrometry (MS) in the NICI mode. Nifedipine, nisoldipine and nitrendipine, which had been added to body fluid samples, could be rapidly extracted by the use of Sep-Pak C18 cartridges. They could be detected both with and without photodecomposition by capillary GC with a DB-1 column, with satisfactory separation and recovery. We recommend the analytical method with photodecomposition, because no special care for light is required during the whole procedure. |
