          摘  要  目的  建立同时测定复方龙胆碳酸氢钠片中10种大黄蒽醌类成分和伪品特征成分土大黄苷含量的方法,用于含大黄复
          方制剂的质量评价。方法  采用超高效液相色谱(UPLC)法对8个生产企业40批次复方龙胆碳酸氢钠片中10种大黄蒽醌类成分
         (芦荟大黄素-8-O-葡萄糖苷、大黄酸-8-O-β-D-葡萄糖苷、大黄酚-8-O-β-D-葡萄糖苷、大黄素-8-O-葡萄糖苷、大黄素甲醚-8-O-β-D-
          葡萄糖苷、芦荟大黄素、大黄酸、大黄素、大黄酚、大黄素甲醚)和土大黄苷的含量进行测定。色谱柱为Agilent Eclipse Plus C18,流
          动相为乙腈-0.1%磷酸溶液(梯度洗脱),流速为0.3 mL/min,柱温为30 ℃,进样量为5 μL。结合主成分分析与聚类分析对含量测
          定结果进行综合分析,并对不同企业样品进行质量评价。结果  上述11种成分在各自检测质量浓度范围内线性关系均良好(r≥
          0.999 3),精密度、重复性、稳定性试验的 RSD 均小于 3%(n 均为 6),平均加样回收率为 96.82%~98.92%(RSD≤1.74%,n=6);
          含量分别为 0.011 7~0.252 0、0~0.323 3、0.131 3~1.236 6、0.081 1~1.056 2、0.015 2~0.189 8、0.001 8~0.152 3、0~0.255 2、
          0.001 9~0.223 4、0.054 3~0.303 0、0.022 7~0.172 2、0~2.835 9 mg/g。3 个主成分的累计方差贡献率为 95.533%;40 批次样品可
          分为4类:a和d企业的样品分别自成一类,f、b、g、e企业的样品为一类,c、h企业的样品为一类。8家生产企业样品中的大黄蒽醌
          类成分含量存在较大差异,且有1家企业的样品检出了土大黄苷。结论  所建UPLC法稳定、可靠,可用于复方龙胆碳酸氢钠片中
          10种大黄蒽醌类成分及土大黄苷的含量测定。

          ABSTRACT   OBJECTIVE To establish a method for the simultaneous determination of 10 rhubarb anthraquinones in Compound
          gentian sodium bicarbonate tablets and the content of rhaponticin,which are the characteristic components of artifacts,and to use the
          method  to  evaluate  the  quality  of  compound  preparation  containing  Rheum  officinale.  METHODS  The  ultra-performance  liquid
          chromatography (UPLC) method was adopted to determine the contents of 10 rhubarb anthraquinones (aloe-emodin-8-O-glucoside,
          rheinic acid-8-O-β-D-glucoside,emodin-8-O-glucoside,chrysophanol-8-O-β-D-glucoside,emodin monomethyl ether-8-O-β-D-glucoside,
          aloe-emodin,rheinic  acid,emodin,chrysophanol,emodin  monomethyl  ether)  and  rhaponticin  in  40  batches  of  Compound  gentian
          sodium  bicarbonate  tablets  from  8  manufacturers. The  determination  was  performed  on  the Agilent  Eclipse  Plus  C18  column  with  a
          mobile  phase  consisted  of  acetonitrile-0.1%  phosphoric  acid  solution (gradient  elution)  at  a  flow  rate  of  0.3  mL/min;  the  column
          temperature  was  set  at  30  ℃,and  the  injection  volume  was  5  μL.  Combining  principal  component  analysis  and  cluster  analysis  to
          synthesize the results of content determination,the quality of samples from different manufacturers was evaluated. RESULTS All of
                                                             above  11  components  showed  favorable  linear  relationships
