DETECTION OF BLOOD PLASMA SCHIZANDRIN B OF DISSIPATING BLOOD STASIS BOTANICAL

摘要

A detection method of blood plasma schizadrin B of dissipating blood stasis botanical is disclosed. The method includes: (1) extracting schizadrin B from plasma of mammalian administered dissipating blood stasis botanical by ethyl acetate with the volume ratio 1:4, whirling 3-5mins, centrifugating at 9600rpm for 10mins, drying and enriching the upper layer at 25-30°C, and redissolving with mobile phase; (2) UPLC/MS measuring: UPLC condition: chromatographic column: Acquity UPLC BEH C 18 , 2.1'100mm, mobile phase A: water-acetonitrile-formic acid 95:5:0.1 v/v/v, mobile phase B: acetonitrile-formic acid 100:0.1 v/v; MS condition: electric spraying ion source(ESI), detecting with positive ion mode, scanning at the range of m/z 150-1200. The method can be used for pharmacokinetics study of schizadrin B in dissipating blood stasis botanical.
