近几年我们对维生素B_6片进行多批次的检验,认为药典中含量测定的溶解法较麻烦,费事费时,在研磨至转移过程中如操作不当会直接影响测定结果的准确性。根据维生素B_6易溶于水的特性,采用非研磨溶解法,简便易行,结果准确。 1.仪器 TU-1221型紫外可见分光光度计;SHZ88-1型台式水浴恒温振荡器。 2.方法
In recent years, we conducted multiple batches of vitamin B_6 tablets test, that the Pharmacopoeia content of the dissolution method is more cumbersome, time-consuming, in the process of grinding to transfer, such as improper operation will directly affect the accuracy of the determination results. According to the characteristics of vitamin B_6 soluble in water, the use of non-abrasive dissolution method, simple and easy, accurate results. 1.
