The detection of ten components of a multi-vitamin preparation by chromatographic methods

Abstract

A method in which chromatography is used for the analysis of multi-vitamin preparations is described. Fat-soluble vitamins are extracted after dissolving the preparation in aqueous ammonia solution and are dectected by thin-layer or gas chromatography. Water-soluble materials are then separated in three thin-layer chromatographic systems and active constituents detected with inorganic phosphors and selective spray reagents.
