In the Azores archipelago (Portugal), forest operations and wood industry generate large amounts of Cryptomeria japonica biomass residues (CJBR), which can be used to produce valuable essential oils (EOs). this study, we evaluated chemical composition antioxidant activities EOs from Azorean C. sawdust (CJS) resin-rich bark (CJRRB). The CJS CJRRB EOs, obtained via hydrodistillation, showed different yield values (0.27% vs. 0.80% v/w, dry weight) also profiles, as assessed using GC/MS. A total 64 85 components were identified in representing 95.7% 96.9% composition, respectively. major EO oxygenated sesquiterpenes (mainly α+β-eudesmol, 1-epicubenol, cubebol), while EO, monoterpene hydrocarbons, including α-pinene, δ-3-carene, limonene (66.6% 6.4% for 0% 64% respectively). Antioxidant activity was estimated (i) two radical-based assays, 2,2-diphenyl-1-picrylhydrazyl (DPPH) 2,2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity, (ii) a lipid model assay, β-carotene-linoleic bleaching (BCBA). Both exhibited concentration-dependent activities, their DPPH, ABTS, BCBA EC50 1107 1275 µg/mL, 260 498 1764 662 results indicate that both able exert mechanisms action. Therefore, may sustainable sources compounds. This study expands biological knowledge CJBR and, consequently, adds more value industry.

Autochthonous Conifers of Family Pinaceae in Europe: Broad Review of Morpho-Anatomical and Phytochemical Properties of Needles and Genetic Investigations

Forests, Journal Year: 2024, Volume and Issue: 15(6), P. 989 - 989

Published: June 5, 2024

Gymnosperms are a very old and small group of plants compared to angiosperms. Contemporary science recognizes about 650 extant conifers worldwide. This review focuses on species the Pinaceae family found in Europe. There 23 from genera Abies, Larix, Picea, Pinus. Some them widespread Europe, but others have fragmented limited distribution classified as relic, endemic, or endangered. The aim this is providing cumulative information variability needle morpho-anatomy, terpenes, n-alkanes, well genetics species, native first morpho-anatomical examinations needles were conducted 19th century. A lot been investigated up now, population many conifer still not known. composition abundance terpenes differ between families also within same genus, pointing their taxonomic importance. n-Alkanes wax surfaces sometimes useful markers variability. most abundant n-alkanes Abies nonacosane (C29), hentriacontane (C31), heptacosane (C27), whereas Larix decidua majority Picea C31 predominant. C29 dominant genus extensive population-genetic studies European representatives focused alba, abies, Pinus nigra, sylvestris, examined endemic such borisii-regis, A. cephalonica, nebrodensis, omorika. These hold significant practical value assessing species’ evolutionary potential, devising strategies for long-term conservation, identifying centers diversity, detecting relict ancestral populations, unveiling cryptic hybrids, elucidating significance species. investigations great only biodiversity level, levels ecology, physiology, taxonomy, evolution.

Abstract Soy protein isolated (SPI) have a wide application in the food packaging, but their water resistance, mechanical properties and antibacterial are not ideal for directly use. In our study, we developed series of SPI composite films loaded with cinnamaldehyde titanium dioxide (TiO 2 ). X‐ray diffraction (XRD), UV scanning spectra (UV) spectro colorimeter were applied to indicate structure films. The incorporation TiO (0.5%) caused subsequent effect on tensile property, blocking vapor (WVP). On other hand, film composed constant amount different concentration showed an excellent synergistic improve moisture content, properties, morphological characteristics. Furthermore, exhibited superior activity when tested against both S. aureus E. coli . microstructure become heterogeneous rough after addition compare control film. findings present study may facilitate re‐evaluation potential using multiple compounds prepare active edible

There is growing concern about the potential risks posed by synthetic additives in industrial products, such as foods, cosmetics, agrochemicals, and personal care products. Many plant-derived essential oils (EOs) have been shown to exhibit excellent antibacterial, antifungal, antiviral, antioxidant activities, may therefore be used natural preservatives these applications. However, most EOs relatively low water solubility are prone chemical degradation during storage. The products of can toxic not able fully exert their biological activity, which limits application. Typically, challenges overcome encapsulating oil an appropriate colloid delivery system. This article begins reviewing sources, extraction, activity mechanisms EOs, then highlights plant-based encapsulation technologies that enhance efficacy. Finally, applications plant system discussed.
