“…It was noticed that the phenolic contents correlate well with DPPH and ABTS assays, with correlation coefficients of 0.8601 and 0.7429, respectively, confirming that phenolic compounds contribute to radical scavenging activity of the fungi extracts, having a redox potential. These results are in agreement with those observed in Camellia sinensis , Annona muricata , Zingiber officinale [ 59 ], and Syzigium aromaticum and Allium sativum [ 60 ].…”

Nowadays, climate change is not the only threat facing our planet. There are also other types of pollution such as waste that poisons soils and water and kills plants, harming humans and animals. Sustainability represents a key issue for the actual Global Citizen. For this reason, our article is dedicated to offering biofriendly solutions to decrease wastes, give them a positive meaning, such as a substrate for an edible oyster fungus with nutritive and biological properties usefully for humans. Three types of wastes such as coconut coir, pine sawdust, and paper waste—representative symbols of pollution in Ecuador—have been tested as suitable growing substrate for the edible fungi Pleurotus ostreatus (Jacq. ex Fr.) P. Kumm by analyzing parameters such as Biological Efficiency, Mushroom Yield, and Productive Rate. The influence of these “waste” substrates on the nutritive (protein content), biological characteristic (antioxidant activity), and the content of human-health-sustaining compounds (phenols, flavonoids) were also evaluated using the Kjeldahal, DPPH, ABTS, FRAP, and Folin–Ciocalteu methods. The results indicate that all the waste products represent desirable substrates for growing the edible fungi, with more focus on coconut coir waste (one of the principal pollution problems in Ecuador), but that also achieved the increase in the fungi’s desirable characteristics. Coconut coir waste could be an environmentally friendly solution that also offers for humans additional nutritive and healthy benefits.

“…Nowadays polyphenols have been applied as a natural phytobiotic and antioxidant supplement to fight enteropathogens and improve gut health and function [ 1 ] Phenolic compounds are universally distributed in plants and phenolics such as gallic acid, syringic acid, ferulic acid, catechin, ellagic acid, naringin, and chrysin are known for their antimicrobial and antioxidant activities [ 2 ]. Phenolic compounds' biological activity are also greatly affected by their interactions with other biomolecules.…”

Background Microencapsulation technology is the fundamental delivery system for encapsulating the natural bioactive compounds especially phenolic in order to developing bioavailability, stability and controlling release. This study was conducted to determine the antibacterial and health-promoting potential of the phenolic rich extract (PRE)-loaded microcapsules obtained from Polygonum bistorta root as a dietary phytobiotic in mice challenged by enteropathogenic Escherichia coli (E. coli). Method The PRE was obtained from Polygonum bistorta root using fractionation by different polarity solvents and the highest PRE was encapsulated by the combination of modified starch, maltodextrin, and whey protein concentrate as wall materials using a spray dryer. Then, the physicochemical characterization (particle size, zeta potential, Morphology and polydispersity index) of microcapsules have been assessed. For the invivo study, 30 mice at five treatment were designed and antibacterial properties were analyzed. Furthermore, relative fold changes in the ileum population of E. coli was investigated using Real time PCR. Results The encapsulation of PRE resulted in the production of phenolic enriched extract-loaded microcapsules (PRE-LM) with a mean diameter of 330 nm and relatively high entrapment efficiency (87.2% w/v). The dietary supplementation of PRE-LM improved weight gain, liver enzymes, gene expression, morphometric characteristics of the ileum and decreased the population of E. coli present in the ileum significantly (p < 0.05). Conclusion Our funding suggested PRE-LM as a promising phytobiotic against E. coli infection in mice.

“…Its oil [30], ethanol extract [8] and supercritical extract [9] of buds have been reported to display the antioxidant activity comparable to butylated hydroxyl toluene (BHT), a synthetic antioxidant. Its antioxidant activity higher than BHT has also been reported [31][32][33]. Furthermore, S. aromaticum has also been revealed to have anti-inflammatory [34][35][36].…”

Phytochemicals and Antidiabetic, Antioxidant and Anti-inflammatory Activities of Ethanol Flower Extract of Syzygium aromaticum (L.) Merr. & Perry (Myrtaceae)

Syzygium aromaticum (L.) Merr. & Perry is a spice that has been used traditionally for centuries to preserve food and treat for a number of ailments. This research was carried out to analyze phytochemicals and to determine antidiabetic, antioxidant and anti-inflammatory activities of 95 % ethanol flower extract from S. aromaticum (FESA). The GC-MS analysis demonstrated the presence of 17 bioactive compounds in FESA, with eugenol (56.17 %) the most active compound. Antidiabetic activity study revealed that the inhibitory activity of the FESA against α-glucosidase enzyme was stronger than the activity of Acarbose, an antidiabetic drug. In addition, the FESA exhibited potent antioxidant activity by inhibiting 2, 2- diphenyl-1-picrylhydrazylhydrate (DPPH) free radicals higher than butylated hydroxyltoluene (BHT), a synthetic antioxidant. Furthermore, the FESA potentially inhibited the nitric oxide (NO) production in lipopolysaccharide (LPS)-induced RAW 264.7 cells but less effective than Diclofenac, a non-steroidal anti-inflammatory drug. The activities of FESA are partly due to the presence of active compounds. The results obtained confirm the antidiabetic, antioxidant and anti-inflammatory properties, and the traditional used of S. aromaticum for the treatment of diabetes and oxidative and inflammatory-related diseases. HIGHLIGHTS The most predominant bioactive compound in FESA is eugenol (56.17 %), analyzed by GC-MS FESA inhibits α-glucosidase activity significantly higher than acarbose, an antidiabetic drug. The FESA is therefore helpful to delay or possibly prevent the development of the diabetic complication The FESA exhibits DPPH radical scavenging activity is more potent than BHT, an antioxidant compound The FESA can provide a novel natural anti- inflammatory agent resource, as evidenced by the inhibitory effect of FESA on nitric oxide (NO) production GRAPHICAL ABSTRACT
