Essential oils are found in various parts of the plant body (in the seeds, flowers, bark, or leaves) and are also concentrated in certain special cells or groups of cells (glands). Because of their properties, they are widely used in perfumes, flavorings, and medicines. Their chemical composition differs: A great many, for example, are principally terpenes, compounds of carbon and hydrogen. Others contain aldehydes, ketones, or phenols. Oxygen, sulfur, and nitrogen are present in compounds in others. In general, they are complex mixtures. They are obtained from the plant in various ways, depending upon the nature of the part in which they occur—by compression, by distillation with steam, by dissolving the oils out (extraction) or absorbing them, and by pressure and maceration.
