Thin Layer Chromatographic Detection of Carum bulbocastanum Koch in Carum carvi Linn

Abstract

A rapid thin layer chromatographic method has been developed to detect Carum bulbocastanum Koch in Carum carvi Linn. The volatile essential oils are developed on silica gel G plates, using benzene-petroleum ether and visualized by 2,4-dinitrophenylhydrazine spray. This procedure can also differentiate mixtures of the 2 seeds.
