摘要
目的建立黄体酮纳米晶体胶囊的溶出度考察方法。方法采用《中国药典》2010年版溶出度测定第一法,以900 ml浓度为0.25%十二烷基硫酸钠溶液为溶出介质,转速75 r/min,溶出时间为45 min。使用HPLC法对溶出样品检测,采用Agilent TC C18色谱柱(150 mm×4.6 mm,5μm);流动相:甲醇-乙腈-水(35∶40∶25,V/V/V);流速:1.0 ml/min;检测波长:241 nm;柱温:25℃;进样量:20μl。结果本方法平均回收率为100.02%(n=15);溶液在24 h保持稳定(RSD=0.92%,n=8);在2.78-66.7μg/ml范围内线性关系良好(r=1,n=6)。结论方法简便、灵敏、准确、专属性强,可用于黄体酮纳米晶体胶囊溶出度的检测。
Objective To establishe an HPL C method to determine the dissolution of progesterone nanocrystal capsule. Methods The dissolution was determined by the first method described in Chinese pharmacopoeia (ChP) 2010. Totally 900 ml of 0.25% sodium lauryl sulfate solution were used as dissolution media, and the rotation speed was 75 r/min. The dissolution time was 45 min and the dissolution was determined by HPLC. The HPLC column was Agilent TC C18 column (150 mm×4.6 mm,5μm). The mobile phase was methanol-acetonitrile-water (35∶40∶25,V/V/V), with a flow rate of 1.0 ml/min and the detection wavelength of 241 nm. The column temperature was 25℃and the injection volume was 20 μl. Results The average recovery of the method was about 100.02%(n=15 ), and the stability of working solutions was acceptable in 24 h (RSD=0.92%,n=8). The calibration curves showed good linearity (r=1,n=6) within ranges of 2.78-66.7 μg/ml. Conclusion The method is convenient and sensitive in the dissolution determination of progesterone nanocrystal capsule.
