Methods for determination of vitamins by means of high performance liquid chromatography (HPLC). II. Determination of vitamin A (author's transl)

A method is described for the rapid determination of vitamin A in vitamin-concentrates, precursors and mineral supplements. After saponification of the sample, the vitamin A is extracted with petroleum-ether. In this extract the vitamin A is determined spectrophotometrically by HPLC without further...

Description
Summary:A method is described for the rapid determination of vitamin A in vitamin-concentrates, precursors and mineral supplements. After saponification of the sample, the vitamin A is extracted with petroleum-ether. In this extract the vitamin A is determined spectrophotometrically by HPLC without further clean-up.
