          摘   要  目的  建立测定盐酸氨基葡萄糖片中5-羟甲基糠醛(5-HMF)含量的方法,分析其含量变化规律及影响因素。方法  采用
          高效液相色谱法对5-HMF进行定量测定,以Shim-pack GIST C18-AQ为色谱柱,0.1%磷酸溶液-甲醇(90∶10,V/V)为流动相,柱温为
          30 ℃,检测波长为284 nm,流速为1.0 mL/min,进样量为20 μL。通过不同温度反应动力学实验分析5-HMF含量与反应温度、反
          应时间的相关性,建立其形成动力学模型。结果  5-HMF检测质量浓度的线性范围为0.057~5.698 μg/mL(r=0.999 9);检测限为
          5.70 ng/mL,定量限为 17.09 ng/mL;精密度、重复性和稳定性(24 h)试验的 RSD 均小于 1.0%(n=6);加样回收率为 99.38%~
          99.73%(RSD=0.53%,n=9)。8批样品含量为4.10~35.13 μg/g。反应动力学实验数据拟合结果显示,随着反应温度升高、反应时
          间延长,样品中5-HMF含量越高。50、60、70、80 ℃下,5-HMF含量与反应时间均呈线性关系,符合零级动力学模型,反应速率常
          数分别为6.789、7.715、8.815、11.430。结论  所建含量测定方法专属性强、灵敏度高、准确度好;反应温度和反应时间是影响盐酸
          氨基葡萄糖片中5-HMF形成的重要因素,其含量变化规律符合零级动力学模型。

          ABSTRACT    OBJECTIVE  To  establish  the  method  for  the  content  determination  of  5-hydroxymethylfurfural (5-HMF)  in
          glucosamine hydrochloride tablets, and to analyze its regularity and influential factors. METHODS Quantitative analysis of 5-HMF
          was performed using high-performance liquid chromatography. The analysis was conducted on Shim-pack GIST C18-AQ column with
          mobile  phase  consisted  of  0.1%  phosphoric  acid  solution-methanol (90∶10,  V/V)  at  the  flow  rate  of  1.0  mL/min.  The  column
          temperature was 30 ℃, and detection wavelength was 284 nm. The injection volume was 20 μL. Reaction kinetics test of different
          temperatures was adopted to analyze the relationship of 5-HMF content with reaction temperature and reaction time, and utilized to
          build  its  formation  kinetic  model.  RESULTS  The  linger  range  of  5-HMF  was  0.057-5.698  μg/mL (r=0.999  9).  The  limits  of
          detection  and  quantitation  were  5.70  and  17.09  ng/mL;  RSDs  of  precision,  repeatability  and  stability (24  h)  tests  were  all  lower
          than 1.0% (n=6). The average recoveries ranged from 99.38% to 99.73%(RSD=0.53%, n=9). The contents of the 5-HMF in 8
          batches  of  samples  ranged  4.10-35.13  μg/g.  Results  of  data  fitting  in  reaction  kinetics  test  showed  that  the  higher  reaction
          temperature  and  the  longer  reaction  time,  the  higher  5-HMF  content  in  the  sample.  At  50,  60,  70  and  80  ℃,  the  relationship
          between  the  content  of  5-HMF  and  the  reaction  time  was  linear,  in  accordance  with  a  zero-order  kinetic  model.  The  reaction  rate
          constants were 6.789, 7.715, 8.815 and 11.430, respectively. CONCLUSIONS The established method has strong specificity, high
          sensitivity, and good accuracy; the reaction temperature and reaction time are important influential factors for the formation of
          5-HMF in glucosamine hydrochloride tables. The change rule of its content conforms to the zero-order kinetic model.
