摘要: | 目的:考察妇科止带胶囊在加速和室温条件下的稳定性。方法:采用高效液相色谱法测定制剂中盐酸小檗碱的含量:色谱柱为Diamonsil C18,流动相为甲醇-0.7%三乙胺(磷酸调pH至3)(50 ∶ 50,V/V),流速为1 ml/min,检测波长为265 nm,柱温为45 ℃,进样量为5 μl。按2015年版《中国药典》方法考察制剂的水分、崩解时限、加速稳定性、长期稳定性。结果:盐酸小檗碱检测质量浓度线性范围为0.021 7~0.173 6 mg/ml(r=0.999 9);精密度、稳定性、重复性试验的RSD<2%;加样回收率为97.24%~101.73%(RSD=1.72%,n=6)。结论:该制剂水分、崩解时限、加速稳定性、长期稳定性均符合质量标准。 |
ABSTRACT: | OBJECTIVE:To study the stability of Fuke zhidai capsule at accelerated testing and room temperature. METHODS: HPLC was conducted to determine the content of berberine hydrochloride in the preparation: the column was Diamonsil C18 with mobile phase of B methanol -0.7% triethylamine(pH adjusted to 3 by phosphate)(50 ∶ 50,V/V) at a flow rate of 1 ml/min; detection wavelength was 265 nm, with a column temperature at 45 ℃, and the injection volume was 5 μl; its moisture, disintegration time, accelerated stability and long-term stability were studied according to the 2015 edition of Chinese Pharmacopoeia. RESULTS: The linear range of berberine hydrochloride was 0.0217-0.1736 mg/ml(r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 2%; recovery was 97.24%-101.73%(RSD=1.72%,n=6). CONCLUSIONS:The moisture, disintegration time, accelerated stability and long-term stability were all in line with the quality standards. |
