Abstract
The present invention relates to a determination method of a blood plasma amygdalin of body resistance-strengthening and blood stasis-dissipating botanical composition, comprising the following steps: (1) first adding 2-5 mol/L phosphoric acid to the plasma of mammals administered with the blood stasis-dissipating botanical composition, and mixing to homogenize, the volumetric ratio of plasma to phosphoric acid is 1:2-3, applying the solution to a small column of Waters Oasis HLB activated by methanol and water, after leaching by water and 80-100% methanol and eluting by 0.2-1% ammonia-methanol, drying through evaporation and enriching the eluent at 25-30° C.; and re-dissolving with a mobile phase; (2) UPLC/MS determination method: chromatographic conditions: chromatographic column: Acquity UPLC BEH C, 2.1×100 mm, mobile phase A: Water-Acetonitrile-Formic acid 95:5:0.1 v/v/v, mobile phase B: Acetomtrile-Formic acid 100:0.1 v/v; MS conditions: electrospray ionization (ESI) ion source, detection in the positive ion mode, and the mass scanning range m/z 150˜800. The present invention can be used for pharmacokinetic studies of amygdalin of body resistance-strengthening and blood stasis-dissipating botanical composition.
