The gas chromatographic conditions for the assay of vitamins D were described. The analysis was performed on Shimazu Gas Chromatograph GC-4AP equipped with a hydrogen flame ionization detector. Glass columns (4 i.d.×1000mm) packed with 1.5% OV-17 on Shimalite W, 80-100 mesh, silanized, were operated at 240° and a flow rate of 40ml/min (N2) was maintained. Adoption of “unmodified” D as an analytical form and good GLC resolution under the operated condition made the procedure more simple and time-saving. Employment of 7-dehydrocholesteryl acetate as an internal standard enhanced the accuracy of the analysis. Satisfactory result was obtained in the determination of vitamins D2 and D3 in mixtures.
