          摘   要  目的  建立一叶萩药材的质量控制方法。方法  参照2020年版《中国药典》(四部)方法对一叶萩药材进行显微鉴别和薄
          层色谱(TLC)鉴别,并测定药材中的水分、总灰分及酸不溶性灰分、醇溶性浸出物;采用高效液相色谱(HPLC)法测定药材中一叶
          萩碱的含量。结果  一叶萩药材的粉末呈灰绿色,气孔、花粉粒、草酸钙簇晶、导管等显微特征明显。TLC鉴别结果显示,16批药
          材样品的供试品色谱中,在与一叶萩碱、芦丁、槲皮素对照品及一叶萩对照药材色谱相应的位置上分别显相同颜色的斑点。16批
          药材样品的水分、总灰分、酸不溶性灰分、醇溶性浸出物的平均质量分数分别为9.26%、6.96%、1.17%、28.89%。一叶萩碱进样量在
          0.052 4~0.524 0 µg范围内与峰面积成良好的线性关系(R =0.999 8);精密度、重复性、稳定性(24 h)试验的RSD均小于3%(n为6
                                                      2
          或7);平均加样回收率为97.47%,RSD为1.63%(n=6)。16批药材样品中的一叶萩碱含量为1.003~6.872 mg/g。结论  建立了一
          叶萩药材的质量控制方法,并初步拟定该药材中水分、总灰分及酸不溶性灰分分别不得过12.0%、9.0%、2.0%,醇溶性浸出物不得
          少于20%,一叶萩碱含量不得低于1.00 mg/g。

          ABSTRACT    OBJECTIVE  To  establish  the  quality  control  method  of  Flueggea  suffruticosa.  METHODS  The  microscopical
          identification  and  thin  layer  chromatography (TLC)  of  F.  suffruticosa  were  carried  out,  and  the  mass  fractions  of  moisture,  total
          ash,  acid-insoluble  ash  and  alcohol-soluble  extracts  in  F.  suffruticosa  were  measured  based  on  the  2020  version  of  Chinese
          Pharmacopoeia (part  Ⅳ ).  The  content  of  securinine  in  medicinal  materials  was  determined  by  high  performance  liquid
          chromatography. RESULTS The powder of F. suffruticosa was gray-green, with obvious microscopic characteristics such as pores,
          pollen  grains,  calcium  oxalate  cluster  crystals,  ducts.  The  results  of  TLC  identification  showed  that  in  the  chromatograms  of  16
          batches of medicinal samples, the same color spots were found on the corresponding positions of the chromatograms of securinine,
          rutin,  quercetin  and  F.  suffruticosa  control.  The  average  mass  fractions  of  moisture,  total  ash,  acid-insoluble  ash  and  alcohol-
          soluble extracts in 16 batches of medicinal materials were 9.26%, 6.96%, 1.17% and 28.89%, respectively. The injection volume of
          securinine in the range of 0.052 4-0.524 0 µg had a good linear relationship with the peak area (R =0.999 8). RSDs of precision,
                                                                                     2
          repeatability  and  stability (24  h)  test  were  all  less  than  3% (n=6  or  7). The  average  recovery  of  sample  was  97.47%,  RSD  was
          1.63% (n=6). The content of securinine in 16 batches of medicinal materials was 1.003-6.872 mg/g. CONCLUSIONS The quality
          control  method  of  F.  suffruticosa  is  established,  and  the  mass  fractions  of  moisture,  total  ash  and  acid-insoluble  ash  should  not
          exceed 12.0%, 9.0% and 2.0%, respectively; the alcohol-soluble extract should not be less than 20%, and the content of securinine
          should not be less than 1.00 mg/g.
