“…This can be explained by the higher content of natural polyphenol, which are responsible for strong antioxidant activity, due to their ability to neutralize and eliminate free radicals [ 44 ]. The effectiveness of natural antioxidants for limiting lipid oxidation and extending the shelf-life of meat products was demonstrated in a previous study [ 45 ], which showed that Tara pod powder, when battered with pork meat, had high antioxidant activity and retarded lipid oxidation during chilled storage. The results obtained are consistent with those reported by Azman et al [ 46 ] who found that 0.1% Convolvulus arvensis samples were more stable ( p < 0.05) than samples treated with 0.1% BHT.…”

Radical Scavenging and Antioxidant Activity of Anthyllis Vulneraria Leaves and Flowers

The main targets of this work were to determine the phenolic content of Anthyllis vulneraria (A. vulneraria) leaves and flowers and to evaluate their antioxidant activity. Total polyphenols and flavonoid content (TPC and TFC, respectively) were determined. Antioxidant capacity was evaluated by the Ferric Reducing Antioxidant Power (FRAP), the Oxygen Radical Absorbance Capacity (ORAC), the Trolox Equivalent Antioxidant Capacity (TEAC) and the diphenyl picrylhydrazyl (DPPH) assays, and by the analysis of primary and secondary oxidation products in oil-in-water emulsions and in raw beef patties during storage. The results revealed that the flowers of the A. vulneraria contained the highest content of total polyphenols and flavonoids and extracts from these tissues exhibited the strongest antioxidant activity, as they were more effective at retarding lipid oxidation in oil-in-water emulsions and raw beef patties than extracts from the leaves which had a potent antioxidant effect only at the beginning of the oxidation process. The results of this study allowed us to obtain a deep knowledge about the properties of A. vulneraria and confirmed the possibility of using its biologically active extracts in the food, cosmetic and pharmaceutical industries.

“…However, the emulsion with the addition of CD3 at Day 25 remained still well below this value. Other studies with an extract from the tara plant of the same genus also gave very promising results, with the formation of hydroperoxides after eight days of storage at 38 °C being below 20 meq hydroperoxides/kg emulsion [41]. Antioxidants can scavenge free radicals at the oil-water interface, creating a protective barrier and preventing radicals from entering the organic phase and accelerating lipid oxidation [42].…”

Caesalpinia decapetala (Roth) Alston (Fabaceae) (CD) is used in folk medicine to prevent colds and treat bronchitis. This plant has antitumor and antioxidant activity. The antioxidant effects of an extract from Caesalpinia decapetala (Fabaceae) were assessed by storage of model food oil-in-water emulsions with analysis of primary and secondary oxidation products. The antioxidant capacity of the plant extract was evaluated by the diphenylpicrylhydrazyl (DPPH), Trolox equivalent antioxidant capacity (TEAC), oxygen radical absorbance capacity (ORAC) and ferric reducing antioxidant power (FRAP) assays and by electron paramagnetic resonance (EPR) spectroscopy. Lyophilized extracts of CD were added at concentrations of 0.002%, 0.02% and 0.2% into oil-in-water emulsions, which were stored for 30 days at 33 ± 1 °C, and then, oxidative stability was evaluated. The CD extract had high antioxidant activity (700 ± 70 µmol Trolox/g dry plant for the ORAC assay), mainly due to its phenolic components: gallic acid, quercetin, catechin, 4-hydroxybenzoic acid and p-coumaric acid. At a concentration of 0.2%, the extract significantly reduced the oxidative deterioration of oil-in-water emulsions. The results of the present study show the possibility of utilizing CD as a promising source of natural antioxidants for retarding lipid oxidation in the food and cosmetic industries.

“…Although the three polyphenols do not appear to be present in Arabidopsi s, they have been detected in many other families of P. syringae host plants (Table EV3). For instance, TA is widely distributed among Fabaceae , Rubiaceae , Fagaceae , and Theaceaea ; PGG exists in Fabaceae and Meliacea ; EGCG has been detected in Theaceaea , Fabaceae , Rosaceae, and Actinidiaceae (Ikram & Nowshad, 1977; Savolainen, 1992; Harnly et al , 2006; Shen et al , 2006; Wang et al , 2007; Tomczyk & Latté, 2009; Okuda & Ito, 2011; Bueno et al , 2014; Skowyra et al , 2015; Kim et al , 2016; Ramakrishnan et al , 2016; Choudhary et al , 2020). The proline‐rich proteins (PRP) are secreted by tannin‐consuming animals and interact with tannin on the proline residues (Baxter et al , 1997; Boze et al , 2010).…”

Pseudomonas syringae senses polyphenols via phosphorelay crosstalk to inhibit virulence

et al. 2021

View full text Add to dashboard Cite

Bacteria use a variety of mechanisms, such as two‐component regulatory systems (TCSs), to rapidly sense and respond to distinct conditions and signals in their host organisms. For example, a type III secretion system (T3SS) is a key determinant of the virulence of the model plant pathogen Pseudomonas syringae and contains the TCS RhpRS as a key regulator. However, the plant‐derived compound targeting RhpRS remains unknown. Here, we report that RhpRS directly interacts with polyphenols and responds by switching off P. syringae T3SS via crosstalk with alternative histidine kinases. We identify three natural polyphenols that induce the expression of the rhpRS operon in an RhpS‐dependent manner. The presence of these three specific polyphenols inhibits the phosphatase activity of RhpS, thus suppressing T3SS activation in T3SS‐inducing conditions. The Pro40 residue of RhpS is essential to respond to these polyphenols. In addition, three non‐cognate histidine kinases cooperatively phosphorylate RhpR and antagonize the rhpS mutant phenotype. This work illustrates that plant polyphenols can directly target P. syringae RhpRS, which results in bacterial virulence being switched off via a phosphorylation‐related crosstalk.
