The functionality of nutraceutical foods is attributed to their bioactive compounds. These compounds are widely produced by plants, such as phenolic compounds, which have antioxidant activity and/or antimicrobial activity, acting against damage to macromolecules such as lipids, proteins, and nucleic acids. Secondary plant metabolites, including classes such as phenolic compounds, alkaloids, and terpenoids, have a wide variety of biological activities with medicinal potential. These secondary metabolites are considered bioactive compounds. The Zingiberaceae family received special attention for their large bioactive compound production. Such compounds are useful in foods as herbs, spices, flavorings, and seasonings and in the pharmaceutical and cosmetic industries as antioxidants and antimicrobials. Gingers are recognized as safe by the American Food and Drug Administration (FDA), resulting in no side effects when consumed in moderate amounts. Recent studies show that, in addition to rhizomes, the leaves and flowers of some ginger species have antioxidant activity and consequent medicinal potential. Studies have demonstrated that in vitro and in vivo research is needed to evaluate the efficacy of ginger extracts and understand their role in the modulation of biological and molecular pathways, thus enabling the development of new therapeutic strategies. Thereby, the present work aims to provide a bibliographic review on the antimicrobial activity of Zingiber officinale Roscoe and Alpinia purpurata (Vieill.) K. Schum. (Zingiberaceae), popularly known as ginger and red ginger respectively, and their potential use in the One Health initiative.

Zingiber Officinale Roscoe

Ginger (Zingiber officinale Roscoe) is a common and widely used spice. It is rich in various chemical constituents, including phenolic compounds, terpenes, polysaccharides, lipids, organic acids, and raw fibers. The health benefits of ginger are mainly attributed to its phenolic compounds, such as gingerols and shogaols. Accumulated investigations have demonstrated that ginger possesses multiple biological activities, including antioxidant, anti-inflammatory, antimicrobial, anticancer, neuroprotective, cardiovascular protective, respiratory protective, antiobesity, antidiabetic, antinausea, and antiemetic activities. In this review, we summarize current knowledge about the bioactive compounds and bioactivities of ginger, and the mechanisms of action are also discussed. We hope that this updated review paper will attract more attention to ginger and its further applications, including its potential to be developed into functional foods or nutraceuticals for the prevention and management of chronic diseases.

In this study, blueberry and blackcurrant powder were chosen as the phenolic-rich enrichments for oat bran. A Rapid Visco Analyser was used to form blueberry and blackcurrant enriched oat pastes. An in vitro digestion process evaluated the changes of phenolic compounds and the in vitro antioxidant potential of extracts of pastes. The anthocyanidin profiles in the extracts were characterised by the pH differential method. The results showed that blueberry and blackcurrant powder significantly increased the content of phenolic compounds and the in vitro antioxidant capacity of pastes, while the total flavonoid content decreased after digestion compared to the undigested samples. Strong correlations between these bioactive compounds and antioxidant values were observed. Lipopolysaccharide-stimulated RAW264.7 macrophages were used to investigate the intracellular antioxidant activity of the extracts from the digested oat bran paste with 25% enrichment of blueberry or blackcurrant powder. The results indicated that the extracts of digested pastes prevented the macrophages from experiencing lipopolysaccharide (LPS)-stimulated intracellular reactive oxygen species accumulation, mainly by the Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2) signalling pathway. These findings suggest that the bioactive ingredients from blueberry and blackcurrant powder enhanced the in vitro and intracellular antioxidant capacity of oat bran pastes, and these enriched pastes have the potential to be utilised in the development of the functional foods.

AbstractThe grape pomace is a by-product from the industrial processing of grape juice, which can be used as a source of bioactive compounds. The aim of this study was to separate the phenolic compounds from grape pomace using an acidic aqueous solution with 2 % citric acid as a solvent, using both ultrasound-assisted extraction, with powers of 250, 350 and 450 W and times of 5, 10 and 15 min, and microwave-assisted extraction using powers of 600, 800 and 1,000 W and times of 5, 7 and 10 min. The results showed that for both methods of extraction, the contents of total phenolic compounds and antioxidant activity by ABTS and DPPH increased with time, and microwave at 1,000 W for 10 min corresponded to the best extraction condition. However, the contents of phenolic compounds and antioxidant activity were lower than exhaustive extraction using acidified methanol solution.

Epiphyllum, Hylocereus, and Opuntia plants belong to the Cactaceae family. They are mostly known as ornamental plants but also for their edible fruits, which can potentially be sources of betalains, such as betanin, a natural pigment used in the food industry, e.g., under the European label code E 162. The aim of this work was the identification of betalains (using LC-MS/MS), evaluation of total betalain content (spectrophotometrically), analysis of functional groups (using FT-IR), evaluation of antioxidant activity (using DPPH, ABTS, FRAP, DCFH-DA, and reducing power methods) and evaluation of antimicrobial activity (S. aureus, E. coli, and C. albicans) in fruits of Epiphyllum, Hylocereus, and Opuntia taxa. A total of 20 betalains were identified in the studied Cactaceae fruits. The Epiphyllum pink hybrid had the highest values of total betalains amongst all samples. The highest antioxidant activity was observed in the Epiphyllum pink hybrid, in Opuntia zacuapanensis and O. humifusa fruits. The antimicrobial activity assay showed that cacti fruits were not able to effectively inhibit the growth of E. coli, S. aureus, or C. albicans. Our results prove that these fruits are good sources of natural pigments—betalains. They do not contain toxic compounds in significant amounts and they exhibit antioxidant activity.

Papaya (Carica papaya L) is some fruit rich in antioxidants and an important source for obtaining bioactive compounds. Its production, worldwide for the year 2017, was 13.3 million tons. In its industrial processing is obtained approximately between 15 and 20%, in relation to the weight of the fruit, of husks or epicarp, which are likely to be used in order to obtain organic compounds such as carotenoids and polyphenols, among others, contributing, in addition, to mitigate the effects on the environment, since generally, these shells are thrown into landfills of solid waste, generating serious problems of environmental pollution. The objective of this research was to characterize physicochemically the carotenoid pigments obtained from the papaya epicarp. A papaya epicarp flour was processed and it was determined, both in it and in the fresh epicarp, pH, titratable acidity, moisture content and dry matter. Likewise, the carotenoid content, the antioxidant activity and the content of phenolic compounds were determined. The results showed high values for physicochemical parameters. The content of carotenoid compounds for the fractions of β-carotene, α-carotene, β-cryptoxanthin, Zeaxanthin and lycopene ranged between 8,587 and 4,070 mg/100g of epicarp, with the highest value corresponding to β-cryptoxanthin and the lowest value the lycopene fraction. The antioxidant activity, expressed as inhibition of the DPPH radical, gave a value of 58.77 ± 3.038 IC50 mg/ml. The content of phenolic compounds measured in mg of gallic acid equivalents/g gave a result of 24.948 ± 0.728. The data obtained allow us to conclude that said flour can be used as a source of bioactive compounds and natural pigments both in the food industry and in the technical and pharmaceutical industries.

In this study the effect of pollen source (mesquite and catclaw) on the sensory characteristics (appearance, color, aroma, taste, consistency and visible impurities), and physicochemical properties of raw propolis, and the phenolic content and biological activities of propolis extracts (PEs) was determined. The phenolic composition of PEs was determined by the total phenolic (TPC), flavone and flavonol (FFC), and flavanone and dihydroflavonol content (FDC). The individual phenolic components were analyzed by HPLC-DAD. The antioxidant activity was determined by the ferric-reducing power (FRAP) and free-radical scavenging activity (FRS). The antibacterial activity was evaluated against Gram-positive (Staphylococcus aureus and Listeria innocua) and Gram-negative (Echerichia coli and Salmonella thyphimurium) bacteria. The results showed that sensory characteristic and physicochemical properties of mesquite and catclaw propolis complied with international quality regulations. Fifteen phenolic compounds were identified, of which pinocembrin, naringenin, galangin, chrysin and quercetin were found a high concentration (> 3 mg/g). Mesquite propolis had the highest phenolic content (TFC and FDC), as well as antioxidant activity (> 2.5 mg Fe (II) equivalent/g; > 40% of DPPH radical inhibition) and antibacterial activity against Gram-positive bacterias in the order S. aureus > L. innocua (> 50% of inhibition for both bacterias at 500 µg/mL). These results indicating that pollen source affect the sensory characteristics and physicochemical properties of propolis, as well as the biological activity of their extracts.
