摘要
目的:建立尼美舒利醇质体中尼美舒利含量以及醇质体包封率的测定方法。方法:采用HPLC法测定尼美舒利含量;采用葡聚糖凝胶法分离尼美舒利醇质体和游离药物以测定包封率。结果:尼美舒利在2~100μg.mL-1的范围内线性良好(r=0.9999),平均加样回收率的范围100.01~100.80%,所测醇质体的平均包封率(92.12±0.13)%。结论:该方法准确可靠、简单快速、重复性好,可用于尼美舒利醇质体药物含量及包封率的测定。
Objective: To establish a method to determine the content and entrapment efficiency of nimesulide encapsulated in ethosomes. Methods: The HPLC analysis was carried out to determine the content of nimesulide. The nimesulide ethosomes and nimesulide were isolated by Gel -filtration for the entrapment efficiency determination. Results: The linear range of nimesulide was 2 - 100 μg .mL^- 1 ( r = 0. 9999). The average recovery range of nimesulide was 100.01 -100.80%. The average entrapment efficiency was (92.12 ±0.13)%. Conclusion: The method is simple, precise and replicable and can be used to determine the content of total nimesulide in ethosomes and entrapment efficiency.
