          摘   要  目的  测定厚朴排气合剂主要药效成分厚朴酚、和厚朴酚在不同种属动物血浆中的蛋白结合率并比较种属差异。方法
          采用平衡透析法,将牛、兔、大鼠血浆(即透析内液)置于4.5、9.0、13.5 μg/mL(按厚朴排气合剂饮片质量计)的含药透析液中平衡透
          析24 h;采用超高效液相色谱-串联三重四极杆质谱技术检测透析内、外液中厚朴酚、和厚朴酚的质量浓度,计算血浆蛋白结合率
          并进行比较。结果  在 4.5、9.0、13.5 μg/mL 质量浓度下,厚朴酚在牛血浆中的蛋白结合率分别为(68.13±4.52)%、(74.34±
          1.12)%、(86.22±0.50)%,在兔血浆中的蛋白结合率分别为(59.55±4.62)%、(72.81±4.56)%、(86.40±1.91)%,在大鼠血浆中的蛋
          白结合率分别为(56.63±2.87)%、(77.81±1.83)%、(83.18±0.65)%;和厚朴酚在牛血浆中的蛋白结合率分别为(34.82±1.67)%、
         (40.29±3.28)%、(63.57±0.59)%,在兔血浆中的蛋白结合率分别为(34.25±5.62)%、(62.12±7.36)%、(80.86±4.01)%,在大鼠血
          浆中的蛋白结合率分别为(37.06±3.28)%、(52.61±1.69)%、(79.83±7.38)%,组间比较差异大多具有统计学意义(P<0.05或P<
          0.01)。结论  厚朴排气合剂主要药效成分厚朴酚、和厚朴酚的血浆蛋白结合率存在明显的种属差异,且有一定的浓度依赖趋势。

          ABSTRACT    OBJECTIVE  To  determine  the  protein  binding  rates  of  main  effective  components  in  Houpu  paiqi  mixture  as
          magnolol and honokiol in animal plasma of different species, and compare the differences among species. METHODS The plasma
          of  bovine,  rabbit  and  rat (internal  dialysate)  was  placed  in  4.5,  9.0  and  13.5  μg/mL (according  to  the  weight  of  the  decoction
          pieces of Houpu paiqi mixture) dialysate containing drug for 24 h by equilibrium dialysate method. The concentrations of magnolol
          and  honokiol  in  dialysis  internal  and  external  fluids  were  determined  by  ultra-performance  liquid  chromatography-tandem  triple
          quadrupole  mass  spectrometry,  and  the  plasma  protein  binding  rates  were  calculated  and  compared.  RESULTS  At  the
          concentrations  of  4.5,  9.0  and  13.5  μg/mL,  the  protein  binding  rates  of  magnolol  were (68.13±4.52)%, (74.34±1.12)%  and
         (86.22±0.50)%  in  bovine  plasma, (59.55±4.62)  % , (72.81±4.56)%  and (86.40±1.91)%  in  rabbit  plasma,  and (56.63±
          2.87)%, (77.81±1.83)%  and (83.18±0.65)%  in  rat  plasma,  respectively.  The  protein  binding  rates  of  honokiol  were (34.82±
          1.67)% , (40.29±3.28)%  and (63.57±0.59)%  in  bovine  plasma, (34.25±5.62)% , (62.12±7.36)%  and (80.86±4.01)%  in
          rabbit  plasma,  and (37.06±3.28)% , (52.61±1.69)%  and (79.83±7.38)%  in  rat  plasma,  respectively.  There  was  generally
          statistical  significance  among  those  groups (P<0.05  or  P<0.01).  CONCLUSIONS  There  are  significant  species  differences  in
          plasma  protein  binding  rates  of  magnolol  and  honokiol,  the  main  effective  components  of  Houpu  paiqi  mixture,  in  a  certain
          concentration-dependent trend.
