Abstract

Essential oils are odorous oily liquids derived from plant material. Essential oils have been used extensively from pre-history times as, bactericidal, fungicide, insecticidal, and medical purposes. Many of these components are produced as secondary metabolites in plants. Therefore, the development of production of these components are important in terms of medicine and industry. In this study, bioengineering methods used in the production, development and metabolism of essential oils in plants were investigated. Recent developments on this issue have been summarized and reported.

Highlights

  • People use plants to obtain an important portion of the essential foods they need to survive

  • Medicinal plants are used in nutrition, cosmetics, body care, incense or religious ceremonies while aromatic plants are used for good smell and taste (Bayram et al, 2010)

  • Essential oils are mixtures that are extracted from plant roots, bodies, leaves, fruits, barks and flowers by different methods; are in liquid form at room temperature, volatile with a strong scent, can be crystalized, are usually colourless or light yellow, give the plant its characteristic smell and flavour, contain several compounds, have lipoid structure that can be drifted with water, contain oxygenated terpenoit derivatives, benzoid compounds, nitrogen or sulphur and are usually comprised of terpens (Adams, 2004;, Bayrak, 2006;, Çalikoğlu et al, 2006;, Evren and Tekgüler 2011;, Yaylı, 2013;, Kaya and Ergönül 2015)
