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.
