Review ArticlesPeel Oils of Different Types of Citrus sinensis L. and C. auarantium L. Growing in Egypt

A comparative chromatographic study including column chromatography, TLC, and GLC was carried out on the peel essential oils (cold-pressed and steam-distilled) of different types and varieties of Citrus sinensis L. and C. aurantium L. growing in Egypt. A mineral oil capillary column was successfully employed in the GLC analysis of these oils. IR patterns of the oils were used in the differentiation between the cold-pressed and steam-distilled oils.
