1'-乙酰氧基胡椒酚乙酸醋片的溶出度测定方法
Pharmaceutical Journal of Chinese People's Liberation Army(2011)
Abstract
目的 测定1'-乙酰氧基胡椒酚乙酸酯片的溶出度.方法 采用高效液相色谱法测定含量,λmax=218nm,溶出度以小杯法测定,转速50 r/min,溶出介质为200 ml蒸馏水.结果 当1'-乙酰氧基胡椒酚乙酸酯浓度为10 -100 μg/ml时,浓度与峰面积线性关系良好,回归方程为:Y=21941X+9741.2,r2=0.9999(n=3).30 min取样,主药溶出标示量90%以上.结论 该方法操作简便、快捷、准确、灵敏度高,为1'-乙酰氧基胡椒酚乙酸酯片剂的溶出度测定提供了方法学依据.
