Postharvest Care of Medicinal and Aromatic Plants: A Reservoir of Many Health Benefiting Constituents
Published in Amit Baran Sharangi, K. V. Peter, Medicinal Plants, 2023
It is a very ancient and easiest method of performing the distillation process (Meyer-Warnod et al., 1984). This particular process is mainly adopted for extraction of EOs from grounded materials of plant parts (Öztekin and Martinov, 2007; Munir, 2010). In this process, the plant materials are submerged in water which is then heated to get out the steam along with the necessary components. Different plant substances like powder of cinnamon bark or spices can be incorporated to hydrodistillation for essential oil extraction. Extraction from rose or orange can be done by the help of this technique (Öztekin and Martinov, 2007; Munir, 2010).

The essential oils are also represented within the secondary metabolites, which are composed of a mixture of organic and volatile compounds (Tisserand and Young 2014). These compounds are extracted by hydrodistillation in two forms: the classic one, in which the plant material is boiled in water or the modern one, where steam passes through plant material (Tisserand and Young 2014). The volatile compounds are carried away by the water vapor and then condensed when passing through a cold chamber. In this way, two immiscible phases are formed: the aqueous and the oily. They are separated using a separating funnel. Through this technique, Brito et al. (2018) obtained essential oils from Croton argyrophyllus leaves with broad antibacterial activity. Oil samples from Syagrus coronata seeds (Santos et al. 2019) and from the aerial parts of Osmunda regalis (Bouazzi et al. 2018) were also extracted by hydrodistillation with antibacterial action against Staphylococcus aureus and antiviral against Coxsackie B, respectively.

The H. scabrum L. plant used in the study was picked during the flowering season in the Erzurum Palandöken region and dried in the shade (Figure 1). A voucher specimen has been deposited in the Herbarium of Ataturk University (voucher No. ATA9306) in Erzurum, Turkey. The dried plants were pulverized in a mill, and the ground plants were isolated using Clevenger equipment and the hydrodistillation process. The essential oils were refined with Na2SO4 after being washed with chloroform (sodium sulfate). In a rotating evaporator, essential oils were extracted by eliminating chloroform at low pressure and temperature. The acquired essential oil's percent yield was calculated. It was kept in a sealed glass tube for use in the experiment16.

Hydrodistillation is a physicochemical process of aqueous diffusion, hydrolysis of plant or microbial cell substances, and their decomposition by heat. Hydrodistillation can be carried out as water distillation, water and steam distillation, or direct steam distillation. Water distillation is the soaking of lichen material followed by boiling the resulting mixture. Hot water releases essential oils from oil glands whereas steam distillation extracts steam-volatile essential oils by passing vaporized steam through the lichen sample. The main disadvantage of this technique is the loss of heat-labile compounds at a high-temperature distillation. Hydrodistillation was used for the extraction of essential oils with potent bioactivities from two lichens species, Evernia prunastri, and Ramalina farinacea [78].

Fresh leaves of M. piperita, M. spicata, M. longifolia, C. camphora, C. flexuosus and rhizomes of H. spicatum and C. aromatica (each 2 kg) used for the extraction of EOs. The material from each plant species was subjected to hydrodistillation for three hours using a Clevenger-type apparatus which resulted in yield 0.2, 0.12, 0.2, 1.0, 0.6, 0.2, and 0.25 ml of oil per 100 g of M. piperita, M. spicata, M. longifolia, C. camphora, C. flexuosus, H. spicatum and C. aromatica, respectively. Each EO sample was dried over anhydrous sodium sulfate and placed at low temperature in refrigerator (4°C) until used in experiments.
