摘    要:应用人工神经网络原理,采用Levenberg-Marquardt BP算法,对于吸收光谱严重重叠的维生素B1,B2,B6和烟酰胺4组分同时进行含量测定。四者的平均回收率分别为100%,98%,96%,100%。该方法用于复合维生素B片剂中B1,B2,B6和烟酰胺的同时测定,获得较满意的结果。实验表明,该方法与现有的算法相比具有训练速度快、预测结果准确度高等特点,有望能成为多组分分析的有效方法之一。

关 键 词:人工神经网络  维生素B1  维生素B2  维生素B6  烟酰胺  同时测定  含量测定  多组分分析

Abstract:By means of artificial neural network and the Levenberg Marquardt back propagation train algorithm, the multicomponents of vitamin B 1,B 2,B 6 and nicotinamide were determined simultaneously, though their spectra are overlapped. The mean recovery of vitamin B 1,B 2,B 6 and nicotinamide were 100%,98%,96% and 100% respectively.The method has been applied to the determination of vitamin B compound tablets with satisfactory results. The results were better than those of other networks in terms of training speed and the accuracy. In conclusion ,the new network spectrophotometry is a good choice for resolving multicomponent.
Keywords:artificial neural network  vitamin B  1  vitamin B  2  vitamin B  6  nicotinamide
