• What are the methods used to extract essential oil from plants?
  • The methods used to extract essential oil from these plants are; steam distillation (SD), solvent-assisted extraction, hydro distillation (HD), ultrasonic-assisted extraction, supercritical fluid extraction and solvent-free microwave extraction (Belhachat et al., 2018). Oil extraction techniques are classified as shown in Fig. 1.
  • How are essential oils extracted?
  • onstituents to be obtained. For the extraction of essential oils, the simplest methods are hydrodistillation and steam distillation while other methods also employed are cold fat extraction, expression, macera
  • How do you extract a medicinal plant?
  • ents of a me-dicinal plant. It is generally carried out by boiling the pla t part for a fi xed period. Hot continuous extraction or solvent extraction technique is one of the most widely used extraction techniques for the pro essing of medicinal plants. The solvent extraction method is simple, well
  • Why are essential oil extraction methods important?
  • Essential oils are very important as they are used as anti-cancer agents, anti-viral agents, anti-spasmodic effects, anti-bacterial agents, anti-diabetic activity, and anti-lipid peroxidation etc. Present study aims to summarize all oil extraction methods and their economic and environmental aspects.
  • What is solvent extraction method?
  • Solvent extraction method This approach uses common solvents like petroleum, acetone, ether, methanol or ethanol, hexane to extract fragile flower components that the application heat cannot separate. In this technique, solvents are mixed with plants sample and then mixture is moderately heated.
  • What is the kinetic model for essential oil extraction from medicinal and aromatic plants?
  • Dual kinetic model for essential oil extraction from medicinal and aromatic plants is written as (Meziane et al., 2019): (13) q t = q ¡Þ [1 ? f e x p (? k 1 t) ? (1 ? f) e x p (? k 2 t)] Various studies have been performed on kinetic modeling of essential oil extraction from aromatic and medicinal plants as shown in Table 7 and Table 8. Table 7.
