摘  要:目的:建立同时测定复方法莫替丁胃内滞留漂浮型缓释片中法莫替丁、阿莫西林和盐酸小檗碱含量的方法。方法:采用高效液相色谱法,使用Kromasil C18色谱柱(4.6 mm×150 mm,5μm),以0.05 mol·L-1磷酸二氢钾溶液(用2 mol·L-1氢氧化钠溶液调p H至5.0)-乙腈-0.01 mol·L-1庚烷磺酸钠溶液(用冰醋酸调p H至3.9)为流动相,梯度洗脱[0~3 min,A-BC(47∶6∶47);3~11 min,A-B-C(47∶6∶47)→A-B-C(41∶18∶41);11~15 min,A-B-C(41∶18∶41)→A-B-C(37.5∶25∶37.5);15~16 min,A-B-C(37.5∶25∶37.5)→A-B-C(27.5∶45∶27.5);16~23 min,A-B-C(27.5∶45∶27.5)],流速1 m L·min-1,检测波长230 nm,柱温30℃。结果:法莫替丁质量浓度在31~106μg·m L-1范围内,与其峰面积呈良好的线性关系,平均回收率(n=3)分别为99.5%、99.0%和99.6%,RSD分别为1.9%、1.8%和1.8%;阿莫西林质量浓度在67~229μg·m L-1范围内,与其峰面积呈良好的线性关系,平均回收率(n=3)分别为101.0%、99.0%和99.2%,RSD分别为1.6%、1.0%和2.3%;盐酸小檗碱质量浓度在49~168μg·m L-1范围内,与其峰面积呈良好的线性关系,平均回收率(n=3)分别为101.1%、98.7%和99.2%,RSD分别为1.6%、1.5%和2.3%。3批样品中法莫替丁的含量分别为43.2、42.6和43.9 mg·g-1,阿莫西林的含量分别为332.8、329.3和335.9 mg·g-1,盐酸小檗碱的含量分别为329.2、327.1和330.1 mg·g-1。结论:本法经方法学验证,可用于复方法莫替丁胃内滞留漂浮型缓释片的质量控制。Objective: To establish a method for determination of famotidine, amoxicillin and berberinein hydrochlofide in compound famotidine gastric floating sustained-release tablets. Methods: The HPLC analysis was performed on a Kromasil C18 column (4. 6 mm× 150 mm, 5 μm) with a mobile phase of monopotassium phosphate (the pH value was adjusted to 5. 0 by 2 mol · L-1 sodium hydroxide solution)-acetonitrile-sodium heptanesulfonate (the pH val- ue was adjusted to 3.9 by glacial acetic acid) using gradient elution [0-3 min, A-B-C(47: 6: 47) ; 3-11 min, A- B-C(47: 6: 47)→A-B-C(41: 18:41 ) ; 11-15 min, A-B-C(41: 18: 41)→A-B-C(37. 5: 25: 37. 5) ; 15-16 min, A -B-C(37. 5:25:37. 5)→A-B-C(27. 5:45:27. 5) ; 16-23 min, A-B-C(27. 5:45:27. 5) ] at a flow rate of 1.0 mL · min-1 , the detection wavelength was 230 nm, and the column temperature was 30 ℃. Results: Good linearig of amotidine, amoxicillin and berbefine hydrochlofide was achieved in the concentration ranges of 31-106 μg · mL-1, 67-229 μg · mL-1 and 49-168 μg · mL-1, respectively. The average recovery of famotidine (n =3) was 99. 5%, 99. 0%, 99. 6%, and the relative standard deviation was 1.9%, 1.8%, 1.8%, respectively. The average recovery of amoxicillin (n = 3 ) was 101.0%, 99. 0%, 99. 2%, and the relative standard deviation was 1.6%, 1.0%,2. 3%, respectively. The average recovery of berberine hydrochloride (n =3) was 101.1%, 98.7%, 99. 2%, and the relative standard deviation was 1.6%, 1.5%, 2. 3%, respectively. In three batches of samples, the content of famotidine was 43.2 mg · g-1,42. 6 mg · g- 1 and 43.9 mg ·g-1 the content of amoxicillin was 332. 8 mg · g-1, 329. 3 mg · g-1 and 335.9 mg· g-1 and the content of berberine hydrochloride was 329. 2 mg· g-1 327. 1 mg · g-1 and 330. 1 mg · g-1. Conclusion: The method is proved to be simple, accurate and reproducible. It can effectively control the quality of compound famotidine gastric floating sus
