Currently Applied Extraction Processes for Secondary Metabolites from Lippia turbinata and Turnera diffusa and Future Perspectives

Abstract: The poleo (Lippia turbinata Griseb.) and damiana (Turnera diffusa Wild) are two of the most valued species in the Mexican semidesert due to their medicinal uses. The conventional essential oil extraction process is hydrodistillation, and for the extraction of antioxidants, the use of organic solvents. However, these techniques are time-consuming and degrade thermolabile molecules, and the efficiency of the process is dependent on the affinity of the solvent for bioactive compounds. Likewise, they generate solv… Show more

“…The fact that factors such as oxidative degradation, enzymatic activities, and polymerisation processes have the potential to compromise the integrity of compounds present in a plant sample provides support for this claim. In light of this, thisresearch followed the methodology proposed by Martínez-Ávila et al, 2021). This research utilised a variety of organic solvents with different polarities for this purpose: dichloromethane, ethyl acetate, and nhexane.…”

“…EOs are originally extracted from various plant components such as leaves, fruit, bark, root, balsam, -73-flowers, seeds, fruits and buds (Kayode et al, 2018). Organic solvents such as ethanol, methanol, n-hexane, petroleum ether, toluene, chloroform and water, as well as other solvents are usually used for extraction (Filly et al, 2016;Martínez-Ávila et al, 2021). Steam distillation is the most common commercial method employed for EOs separation while expression and enfleurage are used for extracting essential oils from the most sensitive flowers by using pressing and partitioning in fat phase, respectively (Vergis el a., 2015).…”

“…Although phenylpropenes constitute a relatively small part of the essential oils, they play a vital role in flavor industry such as eugenol is responsible for the aroma of cloves (Vergis et al, 2015). The aromatic ring of phenylpropens may contain hydroxy, methoxy and methylene dioxy groups; while the propyl side chain may carry hydroxyl or carboxyl group (Martínez-Ávila et al, 2021).…”
