A Fourier transform infrared (FT-IR) spectrometric method was developed for the rapid, direct measurement of diosmin in different pharmaceutical drugs. Conventional KBr-spectra were compared for best determination of active substance in commercial preparations. The Beer-Lambert law and two chemometric approaches, partial least squares (PLS) and principal component regression (PCR+) methods, were tried in data processing.
建立了一种傅里叶变换红外(FT-IR)光谱法,用于快速、直接测定不同药物制剂中的地奥司明。比较了常规的 KBr 光谱,以确定商业制剂中活性物质的最佳测定方法。在数据处理中尝试了 Beer-Lambert 定律和两种化学计量学方法,即偏最小二乘法(PLS)和主成分回归(PCR+)方法。
