The main constituents of the essential oil are phenylpropanoids such as carvacrol, thymol, eugenol and cinnamaldehyde. Uses: Coriander is commercially used as a spice and condiment and for the production of Coriander oil. Oil is "essential" in the sense that it carries a distinctive scent, or essence, of the plant. Coriander also contains a small amount of fixed oil and protein. Chemical compositions analysis of clove extract. The chemical composition of meat from different species is similar in the percentages of nitrogenous compounds (21-22 %) and ash (1.0-1.1 %), but some differences can be observed in relation to fat content and amounts of cholesterol and some vitamins and minerals (Table 2).Other animals such as duck and rabbit deposit little fat in muscles (Kauffman 2012).
