应用一阶导数光谱法测定复方感冒灵片中的扑热息痛含量,可排除其他成分干扰,测定时不必进行繁琐的分离和复杂的计算。实验回收率较好(手动法测定为99.03%±0.65%),对仪器波长精度要求不高。
The determination of paracetamol in Fufang Ganmaoling Tablets by first-order derivative spectroscopy can eliminate the interference of other components and does not require complicated separation and complicated calculations. The experimental recovery rate is good (manual determination is 99.03% ± 0.65%), and the wavelength accuracy of the instrument is not high.
