摘要:

目的:建立肝龙胶囊中肌苷的含量测定方法,为肝龙胶囊的质量控制提供依据。方法:采用Gemini 5u C18 110A(250 mm ×
4.6 mm)色谱柱,流动相水(含0.05%TFA):乙腈(含0.05%TFA),采用梯度洗脱方式,流速0.8 mL/min,柱温30 ℃,DAD检测器,
检测波长为214 nm,进样量10 μL。结果:肌苷在0.202~2.020 μg范围之间峰面积值与进样量(μg)线性关系良好,平均回收率
(n=9)为96.9%,RSD为2.18%。结论:建立的肝龙胶囊中肌苷含量测定方法科学、简便、结果准确,可作为提高肝龙胶囊质量标
准的检测项目。

Abstract:

Objective: To establish a determination method of the content of inosine in Ganlong capsule for providing the basis for
Ganlong capsule quality control. Methods: Gemini 5u C18 110A(250 mm×4.6 mm)chromatographic column, mobile phase water
(0.05%TFA): acetonitrile(0.05% TFA), gradient elution, 0.8 mL/min flow, 30 ℃ column temperature, DAD detector, 214 nm detection
wavelength, 10 μL sample quantity were used in the study. Results: Peak area of inosine between 0.202-2.020 μg range and injection
volume(μg)showed a linear relationship. The average recoveries(n=9)was 96.9% , RSD=2.18% . Conclusion: The established
method of determination Ganlong capsules is scientific, simple and accurate, which can be used to improve Ganlong capsule quality
standard test project.

Key words: Ganlong capsule, inosine, determination
