Review: Eucalyptus globulus essential oil extraction method

Abstract Eucalyptus globulus(one of the speciesEucalyptus) is an essential oil-producing plant that widely used in the medical sector. Generally, the useful part ofEucalyptusis leaves. Bioactive compounds contained in plant essential oils include gallic acid, cypellocarpin A, eucaglobulin, cuniloside and (1S, 2S, 4R)-trans-2-hydroxy-1,8-cineole;-D-glucopyranoside. The presence of these bioactive compounds made of essential oils can be used as an antibacterial, antioxidant, and anti-inflammatory. The extraction method has a major effect on the production of essential oil because it can affect yield and bioactive compound. The extraction methods can be used to produce essential, such as maceration, Ultrasound-Assisted Extraction (UAE), Microwave Assisted Extraction (MAE), water distillation, steam distillation, water-steam and distillation. This review discusses the extraction methods and the main factor can affect the extraction process to produceE.globulusessential oils.
