glands of plant tissue. The oils may be located throughout the entire plant‚ but are often concentrated in the seeds or flowers of the plant.

Another method of oil extraction from these plants is through both solvent extraction and pressing methods. The functional group that is mostly responsible for the characteristic odors and flavors of fruit and flowers is the ester. Although the ester composes
