          摘  要  目的  建立奥卡西平片中有关物质的含量测定方法。方法  采用超高效液相色谱(UPLC)法,以ZORBAX Eclipse Plus C18
          为色谱柱,乙腈-0.01 mol/L乙酸铵溶液(pH6.0)为流动相进行梯度洗脱,流速为0.5 mL/min,检测波长为230 nm,柱温为35 ℃,进
          样量为10 μL。结果  奥卡西平和杂质A、B、C、D、E、I、K、L、N检测质量浓度线性范围分别为0.192~1.440、1.019~7.639、0.208~
          1.559、0.230~1.727、0.389~2.915、0.182~1.364、0.393~2.945、0.199~1.493、0.199~1.490、0.200~1.503 μg/mL(r 均大于 0.999);
          检测限分别为 0.046、0.037、0.049、0.027、0.077、0.040、0.114、0.054、0.055、0.039 μg/mL,定量限分别为 0.152、0.122、0.162、0.090、
          0.258、0.132、0.380、0.181、0.185、0.130 μg/mL;精密度、重复性、稳定性(24 h)、耐用性试验的 RSD 均小于 5.0%;平均回收率为
          92.8%~105.6%(RSD≤3.0%,n=9)。原研制剂样品中仅检出杂质K和未知杂质,其总含量为0.078%~0.083%;国内Ⅰ企业产仿
          制制剂样品中检出杂质A、B、D、I和未知杂质,其总含量为0.147%~0.163%;国内Ⅱ企业产仿制制剂样品中检出杂质A、B、I和未
          知杂质,其总含量为0.085%~0.161%。结论  所建UPLC法快速,灵敏度高,准确度、稳定性、耐用性好,可用于同时测定奥卡西平
          片中9种已知杂质的含量。

          ABSTRACT   OBJECTIVE  To  establish  the  method  for  content  determination  of  related  substances  in  Oxcarbazepine  tablets.
          METHODS  Ultra-high  performance  liquid  chromatography (UPLC)  method  was  adopted  and  the  separation  was  performed  on
          ZORBAX  Eclipse  Plus  C18  column  with  mobile  phase  consisted  of  acetonitrile-0.01  mol/L  ammonium  acetate  solution (pH6.0)
         (gradient elution) at the flow rate of 0.5 mL/min. The detection wavelength was 230 nm and column temperature was set at 35 ℃.
          The  sample  size  was  10  μL.  RESULTS  The  linear  ranges  of  oxcarbazepine  and  impurity A,  B,  C,  D,  E,  I,  K,  L  and  N  were
          0.192-1.440, 1.019-7.639, 0.208-1.559, 0.230-1.727, 0.389-2.915, 0.182-1.364, 0.393-2.945, 0.199-1.493, 0.199-1.490 and 0.200-
          1.503  μg/mL,  respectively (all  r>0.999).  The  detection  limits  were  0.046,  0.037,  0.049,  0.027,  0.077,  0.040,  0.114,  0.054,
          0.055  and  0.039  μg/mL.  The  quantitation  limits  were  0.152,  0.122,  0.162,  0.090,  0.258,  0.132,  0.380,  0.181,  0.185  and  0.130
          μg/mL.  RSDs  of  precision,  repeatability,  stability (24  h)  and  durability  tests  were  all  lower  than  5.0%.  The  average  recoveries
          were  92.8%-105.6% (RSD≤3.0%,  n=9).  Only  impurity  K  and  unknown  impurity  were  detected  in  the  original  preparation
          sample,  with  a  total  content  of  0.078%  to  0.083%;  impurities  A,  B,  D,  I  and  unknown  impurity  were  detected  in  the  generic
          preparations  produced  by  domestic  enterprise  Ⅰ ,  with  a  total  content  of  0.147%  to  0.163%;  impurities  A,  B,  I  and  unknown
          impurity  were  detected  in  the  generic  preparations  produced  by  domestic  enterprise  Ⅱ,  with  a  total  content  of  0.085%  to  0.161%.
          CONCLUSIONS  The  established  method  is  rapid,  sensitive,  accurate,  stable  and  durable.  It  can  be  used  for  the  content
          determination of 9 known impurities in Oxcarbazepine tablets.
