“…In addition to these, variables such as sample size, solvent flow and ecstatic extraction time also influence the extracts yield, as they interfere with the mass transfer rate. Soares et al (2020) reported in their study that aqueous and hydroalcoholic extraction, at 50 and 70%, showed a higher content of phenolic compounds when compared to extraction using absolute ethanol.…”

Eucalyptus leaves are a secondary product of wood production. The pressurized liquid extraction (PLE) technique is an attractive process due to its advantages. The objective of this work was to obtain extracts of Eucalyptus saligna leaves using the PLE technique, and to characterize different extraction time fractions in relation to bioactive compounds and antioxidant and antimicrobial activities. The extraction of E. saligna leaves was carried out in a jacketed extractor at 40 °C, pressure of 10.4 MPa, with a solvent flow of 2.5 mL.min-1 , using 95% ethanol. The system remained pressurized for 30 minutes in static extraction, followed by 180 minutes in dynamic extraction. The levels of total phenols, flavonoids, antioxidant activity and antimicrobial potential against Staphylococcus aureus and Escherichia coli were evaluated. The extraction showed an overall yield of 12.3% after 180 minutes. The total concentrations of phenols and flavonoids were 618.57 mgGAE.g-1 and 160.28 mgQE.g-1 respectively. The extracts showed good antioxidant and antimicrobial potential, with IC50 between 0.016 and 0.043 mg.mL-1 , and MIC against S. aureus and E. coli between 0.313 and 1.25 mg.mL-1. PLE demonstrated efficiency in obtaining extracts of E. saligna leaves with bioactive properties.

“…Oxidative stress arises when there is a disparity between the generation of ROS and the capacity of the antioxidant defense system [13]. However, when present in larger quantities, ROS cause damage to macromolecules including lipids, carbohydrates, nucleic acids, and proteins, which may induce cell aging, and lead to oxidative stress [14][15]. These radicals react with oxygen to form primary oxidation products, primarily hydroperoxides.…”

The disposal and management of waste have been a burning issue due to the continuous food waste generation in various industrial, agricultural, household, and other food sectors. Fruit and vegetable processing can produce food waste, which can be utilized as a low-cost source of bioactive substances. Natural food additives that extend the shelf life of food are currently of great interest due to the negative health effects associated with prolonged consumption of foods containing artificial food additives. This review describes the important properties of natural bioactive compounds extracted from various fruit and vegetable waste including; antioxidant activities and antimicrobial activities. The primary focus of the present review is to highlight the importance of natural bioactive compounds extracted from food waste as a promising alternative to synthetic additives to extend the shelf-life of food products. The solvent used in the extraction process has a great impact on the quantity and quality of the resulting extract of bioactive compounds. Therefore, even though the same plant material has been used, different solvent extracts lead to different antioxidant activities. The natural bioactive compounds extracted from food waste demonstrated antioxidant and antimicrobial activities that could be used to extend the shelf-life of food products. Increasing the storage stability of natural bioactive compounds is a challenging task that can be achieved via encapsulation. This review suggests that using natural bioactive compounds from leftover fruit and vegetable instead of artificial additives can help prolong the shelf life of food.

“…The concentrations of phenolic compounds in the crude extract (grease) that was obtained by the dynamic maceration process with solvent depletion and the spray-dried crude extract were determined using the Folin-Ciocalteu method described by Soares et al (2020) with some modifications. An aliquot of the sample (extract and water-white) will be diluted to a final volume of 1 ml of distilled water.…”

Epidemiological evidence indicates that plant antioxidants activity can treat or help to prevent the development of various diseases. One species with great potential as an antioxidant is Curcuma longa. However, different extraction techniques can influence isolated chemical compounds. This study investigated chemical composition and antioxidant activity of two rhizome extracts of C. longa: hydroethanolic, obtained by exhaustion (HECLex); and dried by a spray dryer (HECLsd). The phytochemical composition was evaluated by GC/MS. Antioxidant activity was evaluated using DPPH and FRAP assays. Total phenolic compounds and soil analyses were performed. The main components of HECLex were ar-turmerone, γ-curcumene, α-turmerone, and β-sesquiphellandrene. The main components of HECLsd were 9,12,15-octadecatrienoic acid, 2,3-bis([trimethylsilyl]oxy)propyl ester, verrucarol, and 1-monolinoleoylglycerol trimethylsilyl ether. HECLsd had significantly higher levels of phenolic compounds and higher antioxidant capacity compared with HECLex. In conclusion, processes of the preparation of C. longa rhizomes alter the chemical components and consequently their biological activity.
