摘 要:目的:建立高效液相色谱法同时测定复方氨酚苯海拉明片中对乙酰氨基酚、咖啡因、盐酸苯海拉明和盐酸麻黄碱的含量。方法:采用迪马 C_(18)色谱柱(200 mm×4.6mm,5 μm);流动相为乙腈(A)-水(磷酸调节 pH 至2.1)(B),梯度洗脱[0 min(15%A)→7 min(50%A)→8 min(15%A)→18 min(15%A)];流速:1.0 mL·min^(-1);检测波长:215 nm;柱温:室温。结果:对乙酰氨基酚、咖啡因、盐酸苯海拉明和盐酸麻黄碱的线性范围分别为0.064~0.51 mg·mL^(-1)(r=0.9999)、0.067~0.54 mg·mL^(-1)(r=0.9995)、0.020~0.14 mg·mL^(-1)(r=0.9998)和0.017~0.14 mg·mL^(-1)(r=0.9999);平均回收率分别为100.1%(RSD=0.5%)、99.6%(RSD=0.8%)、101.4%(RSD=1.0%)和99.2%(RSD=0.6%)。结论:本法简便快速,结果准确可靠,可作为该复方制剂中4种成分的质量控制方法。Objective:To establish a method for the simultaneous determination of paracetamol, caffeine, diphenhydramine hydrochloride and ephedrine hydrochloride in compound paracetamol and diphenhydramine hydrochloride tablets. Method:The chromatographic C18 column(200 mm ×4. 6 mm ,5 μm) was adopted. The mobile phase consisted of acetonitrile(A) -water( adjusted to pH 2. 1 with phosphoric acid) (B) with gradient elution[0 min( 15% A)→7 min(50% A)→ min( 15% A)→18 min( 15% A)] and the flow rate was 1.0 mL ·min^-1 The detection wavelength was 215 nm. Results: The linear response ranges were:0. 064 - 0. 51 mg · mL^-1 ( r = 0. 9999) for paracetamo1,0. 067 - 0.54 mg· mL^- 1 ( r = 0. 9995 ) for caffeine, 0. 020 - 0. 14 mg · mL^-1 ( r = 0. 9998 ) for diphenhydramine hydrochloride and 0. 017 -0. 14 mg · mL^-1( r = 0. 9999 ) for ephedrine hydrochloride respectively. The mean recoveries of paracetamol, caffeine, diphenhydramine hydrochloride and ephedrine hydrochloride were 100. 1% ( RSD =0.5% ) ,99.6% ( RSD = 0. 8% ), 101.4% ( RSD = 1.0% ) and 99.2% ( RSD = 0.6% ) respectively. Conclusion: This method is simple, quick and the result of determination is accurate and reliable. This method is suitable for determination of the four constituents in compound paracetamol and diphenhydramine hydrochlofide.
