Presented To
Department of Science Laboratory Technology
ABSTRACT
Steam distillation and solvent extraction were mainly used in the extraction of essential oil. With steam distillation, it was found out that the oil was 4.51% obtained. Solvent extraction gave its own as 6.30% steam distillation gave a higher purity of oil than solvent extraction while the later gave a higher quantity of oil with impurities.
There was analysis and characterization of the oil results were obtained. The samples were found to contain food nutrients such as protein, oil, amino acid, vitamin A and vitamin C. The oil is very important in the society so it is suggested that larger quantity be extracted from other locally source raw materials to improve the economy of the country.
