Analysis of the Composition of Plant Essential Oil Used in Cereals and Legumes Storage in Senegal

Abstract

Chemical composition of Hyptis spicigera, H. suaveolens and Eucalyptus camaldulensis essential oils isolated by hydrodistillation of plant leaves from Senegal were determined by GC-MS / GC-FID. A total of twenty-nine, thirty-seven and thirty-four components were identified for H. spicigera, H. suaveolens and E. camaldulensis, respectively. H. spicigera oil contained as main components α-pinene (38.9 %), β- pinene (14.7 %) and caryophyllene (12.6 %). For H. suaveolens we obtained at first, in February 1,8-Cineole (19.8%), caryophyllene (16.9 %) and sabinene (11.6% ); at March, sabinene and caryophyllene represented 27.9 % and 20.8 % respectively while 1,8-Cineole decreased from 19.8 to 1.1%. The most important component revealed with E. camaldulensis were spathulenol (31.6 %), p-cymene (11.3 %), bicyclogermacrene (8.2 %) and β-selinene (7.9 %).
