Detection of new trace constituents in the essential oils of Cymbopogon flexuosus

The essential oil of lemongrass is derived chiefly from two important species of Cymbopogon, C. flexuosus, which has been the subject of numerous investigations, and C. citratus, C. flexuosus (Stend.) Wats (sym. Andropogon nardus var. flexuosus Hack), is native to India. Its two strains, SD-68 and OD-19, which have been cultivated at our Kukrail Research Farm, Lucknow, were examined by gas chromatography and the presence of new trace constituents was established for the first time.

A New Method of Separation of Citral from Lemongrass Oil

Although many methods are known for the separation of citral from lemongrass (Cymbopogen flexuosus) oil, like fractional distillation, adduct formation and regeneration, the purity and the yield of citral as separated are not satisfactory. A new method for separation of citral in pure form and in near quantitative yield uses the column chromatographic technique. This method may also be adapted for large scale separation of citral and hence can be of commercial importance.
