title: [Study on the new determination of analginum].
abstract: Analginum in medicine was determined by a new photometric method based on the color formation of Fe(II)-alpha,alpha'-dipyridine complex from alpha,alpha'-dipyridine and Fe (III) which could be reduced by analginum. The method was simple and rapid, and the results obtained were in agreement with those of iodine titration method and ultraviolet photometric method.
