The dichloromethane solvent, alkanes series (C8–C20 and C21–C40), and sodium sulfate anhydrous were purchased from Sigma-Aldrich (Brazil). Nitrogen gas (99.98%) of purity was purchased from White Martins SA (Brazil). Supplies were purchased from Axygen (Brazil) and glass vials for volatile oils storage were purchased in Didática-SP (Brazil).
Hydrodistillation methods are usually used to extract volatile compounds, including essential oil, insoluble in water, from various aromatic and medicinal plants. However, the water or hydrodistillation process is one of the most traditional methods for extracting the oils as well as bioactive compounds [140].
Jyoti Sankar Prusty, in Phytoconstituents and Antifungals, 2022 Hydrodistillation methods are usually used to extract volatile compounds, including essential oil, insoluble in water, from various aromatic and medicinal plants.
A hydrodistillation study in a given time frame will contribute substantial information that can be applied to industrial-scale volatile oil production, by promoting better yield and/or improved sensory qualities of the volatiles, as well as a significant reduction in the use of energy for their manufacture.
At a high extraction temperature, some volatile components may be lost. This drawback limits its use for thermo-labile compound extraction. There are three types of hydrodistillation : water distillation, water-steam distillation, and steam distillation.
