High Performance Liquid Chromatographic-Electrospray Mass Spectrometric Quantification (HPLC/ESI-MS) of Sanguinarine and Chelerythrine in Near Supercritical Carbon Dioxide Extracts from Spiked and Real Plasma Samples
Original language description
Two polar benzo[c]phenanthridine alkaloids, chelerythrine (CHE) and dihydrochelerythrine (DHCHE), were extracted at 35 °C and 10 MPa (15 MPa for real samples) from real and spiked plasma samples with acceptable recoveries (95.1 % and 81.0 %, respectively) using near-critical CO2 modified with aqueous (1:1, v/v) methanol. The alkaloids were quantified by a liquid chromatographic/electrospray mass spectrometric (LC/ESI-MS) method on a Zorbax SB-CN column (75 x 4.6 mm, 3.5 mm particle size) using methanol(organic phase) and 50 mM ammonium formiate (aqueous phase) as a mobile phase. A linear gradient 0 to 1 min - isocratic at 60% aqueous phase (v/v); from 1.0 to 7.0 min - 60% to 71% aqueous phase (v/v); from 7.0 to 18.0 min - 71% to 60% aqueous phase (v/v) was applied. The limit of detection was 1.22 ng (3.50 pmol) for CHE and 0.95 ng (2.72 pmol) for DHCHE per 1 ml of the sample. The linearity of the calibration curves was satisfactory as indicated by coefficients of determination 0.9979

Alkaloidy byly stanoveny HPLC/ESI-MS na koloně Zorbax SB-CN gradientovou elucí mobilní fázi methanol/50 mM mravenčan amonný. LOD byl 1.22 ng (3.50 pmol) pro CHE a 0.95 ng (2.72 pmol) pro DHCHE v 1 ml vzorku. Průměrná návratnost byla 100.1 % pro spajkovaný i reálný vzorek extraktů plasmy. Metodou byly extrahovány a analyzovány reálné vzorky plasmy potkanů.
