摘要
目的:建立HPLC法测去甲氧基姜黄素纳米粒脂质载体(NLC)中药物含量的方法。方法:采用HPLC法测定纳米脂质载体(NLC)中药物的含量。结果表明去甲氧基姜黄素在420nm处有最大吸收,浓度在2.04至52.5mg·mL-1时与吸光度呈良好的线性关系,回归方程为:Y=121.29C X-296.19,r=0.9997(n=6);平均回收率为99.19%,RSD为0.79%。结论:本方法操作简单,且稳定性、准确度和精密度均符合要求,可用于NLC制剂中去甲氧基姜黄素含量的测定。
Objective: To establish the method determination of deme-thoxycurcumin from NLC. Method: HPLC assay was used, 1=420 nm. Result: It had good linearity with the 2.04-52.5mg · mL-1 concentration range of deme-thoxycurcumin . The re- gression is Y =121.29C X -296.19, r =0.9997( n =6) The recovery from the sample was 99.19%, RSD 为 0.79%.Conclusion: This method is could used to quality standards for deme-thoxycurcumin of NLC.
