阿昔洛韦的药理活性量化方法探究

选择B3LYP／6—311＋G（d,p）方法对阿昔洛韦进行了量子化学计算,对其分子构型、偶极矩、疏水参数、红外光谱、自旋密度分布和前线轨道结构进行了详细探究。结果表明,阿昔洛韦能发挥较好的抗氧化作用,模拟计算获得N（3）—H的活性最强。它在体内极性较大的环境下能发挥很好的吸收效果,研究结果可为阿昔洛韦的药理活性提供理论指导。

偏最小二乘法用于阿昔洛韦片的近红外漫反射快速、无损含量测定

目的:采用偏最小二乘法结合近红外漫反射光谱,建立阿昔洛韦片的快速无损含量测定模型.方法:以阿昔洛韦片为分析对象,用光纤探头测定近红外漫反射光谱.对光谱进行不同预处理方法建模并进行比较,多元校正模型为偏最小二乘法.结果:在11995.5～4246.7cm-1波长范围内采用一阶导数结合矢量归一化对光谱进行预处理,结果最优.定量模型的浓度范围为27%～53%.预示集平均回收率为98.69%,RSD为4.60%,RMSEP为0.0526.结论:近红外漫反射光谱法快速,简便,无损,能够用于阿昔洛韦片含量测定.
