Essential Oil Composition of the Flowering Aerial Parts of Sudanese Morettia phillaeana (Del.) DC

摘要

The aim of this study is to present qualitative and quantitative analysis of the essential oil obtained from the flowering aerial parts of Morettia phillaeana growing in the Central Sudan. The essential oil of flowering aerial parts of M. phillaeana, which belongs to Brassicaceae family, was obtained by hydrodistillation method in 0.5% yield and analyzed by GC/MS. Seven compounds representing 93.67% of the oil were identified. Among them 4-isothiocyanato1-Butene (69.35%), isothiocyanatomethyl Benzene (18.88%), cymene (2.65%), C₉H₁₄O₃ (2.3%) and 2-phenyl acetonitrile (2.18%) were the major constituents of the oil. The oil showed a pale yellow colour and a strong characteristic sulfury odour. Compounds like isothiocyanates, glucosinolates and nitriles found in Brassicaceous plants and their breakdown products are beneficial in the past and hold great prospects for the future with respect to an integrated pest management.
