TITLE:
摘要: 目的:建立测定他米巴罗汀片溶出度的方法。方法:采用高效液相色谱法。色谱柱为Diamonsil C18,流动相为甲醇-水-冰乙酸(85 ∶ 15 ∶ 1,V/V/V),流速为1.0 ml/min,检测波长为235 nm,柱温为25 ℃,进样量为20 μl。溶出度测定采用桨法,以pH6.8磷酸盐缓冲液为溶出介质,溶出介质体积为900 ml,转速为50 r/min,60 min取样。结果:他米巴罗汀检测质量浓度线性范围为0.801~2.804 μg/ml(r=0.999 6);精密度、稳定性、重复性试验的RSD<3%;回收率分别为99.58%~100.90%(RSD=0.25%,n=9);3批样品的溶出度测定结果分别为98.25%、96.54%、92.38%(n=6)。结论:该方法简便、准确,灵敏度高,专属性强,适用于他米巴罗汀片的溶出度测定。
ABSTRACT: OBJECTIVE: To establish a method for the dissolution determination of Tamibarotene tablet. METHODS: HPLC was performed on the column of Diamonsil C18 with mobile phase of methanol-water-acetic acid (85 ∶ 15 ∶ 1,V/V/V) at a flow rate of 1.0 ml/min, detection wavelength was 235 nm,column temperature was 25 ℃, and injection volume was 20 μl. The paddle method was used to determine the dissolution, using pH6.8 phosphate buffer dissolution as medium, medium volume was 900 ml, the rotating speed was 50 r/min, taking samples after 60 min. RESULTS: The linear range of tamibarotene was 0.801-2.804 μg/ml (r=0.999 6); RSDs of precision, stability and reproducibility tests were lower than 3%; recovery was 99.58%-100.90% (RSD=0.25%,n=9); the accumulative dissolution rate of 3 batches of samples was 98.25%,96.54%,92.38%(n=6). CONCLUSIONS: The method simple, accurate with high sensitivity and specificity, and suitable for the dissolution determination of Tamibarotene tablet.
