“…The AAI score for gallic acid was the highest, followed by catechin and ascorbic acid compared with one another and Trolox (Trolox). The antioxidant effects of plant samples are linked to their bioactive components, phenolics being the most important [35]. Due to the higher intricacy of flavonoid molecules, the structure-activity correlations (SARs) of flavonoids are frequently more intricate than those of phenolic acids.…”

Leaves of Lannea velutina are used to treat several human pathologies, such as high blood pressure (HBP) and oxidative stress. Rich in bioactive components that promote prevention and therapy, herbal medicines are affordable and have no adverse effects. This work aims to evaluate the phytochemical profile, antioxidant activity, and acute toxicity of water, methanol, ethyl acetate, dichloromethane, and hexane leaf extracts of L. velutina by using suitable experimental paradigms. This shrub's leaves include sterols, saponosides, flavonoids, and tannins, as revealed by a highperformance thin-layer chromatography (HPTLC) profile. The methanol extract exhibited a significant highest total phenolic (533.9 ± 5.05 mg GAE/g DW), flavonoid (59.4 ± 0.6 mg QE/g DW), and condensed tannins (86.9 ± 0.05 CE/g DW) content compared with ethyl acetate and aqueous extracts. By using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capability experiment, the methanol extract demonstrated the highest antioxidant activity (AAI = 2.60) among the other extracts. There was a strong association between flavonoid concentration and hydrophilic antioxidant activity (r = 0.96). The acute oral toxicity test of ethyl acetate, methanol, and aqueous extracts on mice was evaluated by using Economic Cooperation and Development (OECD) guidelines 423. All investigated extracts exhibit a lethal dose (LD50) estimated higher than 2000 mg/kg body weight. This study constitutes a solid scientific basis that could justify the traditional uses of the leaves of L. velutina as a natural source of phenolic compounds for high blood pressure management.

“…The subsequent extraction of the polyphenols from the remaining residues at the reduced EC and, increased pH could have contributed to a polyphenol extract with lower lipophilic polyphenols but richer in hydrophilic polyphenols in stage 2. Lipophilic polyphenols have been reported to have higher antioxidant capacity when compared to hydrophilic ones 35 . Extraction conditions can therefore be manipulated to obtain two polyphenol extracts with different properties.…”

Three‐stage sequential extraction of anthocyanins, polyphenols, and pectin has the potential to enhance the product's functional properties and the economic value of mango (Mangifera indica L.) peels beyond the two‐stage processes (anthocyanin‐pectin and polyphenol‐pectin). A three‐stage process was developed by incorporating a polyphenol extraction stage in a sequential process where anthocyanins and pectin were co‐extracts. Anthocyanins were extracted first (80% ethanol (EC)/2% acetic acid/25 °C/1 h), generating a residue from which polyphenols were extracted (65–85% EC/20–80 min/70 °C), based on a full factorial statistical experiment. Pectin was subsequently extracted from the second‐stage residues (0.25% ammonium oxalate / oxalic acid / 85 °C / 1 h). The economic benefits (net present value (NPV), payback period (PBP), product minimum selling price (PMSP) of the three‐stage sequential process (anthocyanin, polyphenol, and pectin) and the two‐stage processes (anthocyanin‐pectin and polyphenol‐pectin) were evaluated over a plant life of 25 years. Polyphenols and pectin from the three‐stage process had >65% higher antioxidant capacity and up to 10.4% higher purity, respectively, when compared with those from the two‐stage processes. There is also more economic gain from the three‐stage process (NPV −$4 31 285, PBP −3 years, PMSP < $10/kg) than the anthocyanin‐pectin process (NPV −$3 76 917, PBP −3.22 years, PMSP < $10/kg) and the polyphenol‐pectin process (NPV −$235 599, PBP −4.29 years, PMSP < $30/kg). Thus, three‐stage sequential extraction is an economic process, which enables the recovery of three value‐added food ingredients with improved functional properties from mango peels.© 2020 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Vazquez-Olivo et al [16] also reported that ferulic and p-coumaric acids are the main PCs in corn husk; however, they found lower values of ferulic (455.50 mg/100 g) and p-coumaric (351.550 mg/100 g) acids than the ones reported in our study. These differences could be influenced by environmental, pre-and post-harvest, and drying method conditions [23]. For example, we used a drying temperature of 40 • C, while Vazquez Olivo et al [16] used a drying temperature of 70 • C. Previous reports have indicated that a high temperature can cause PC losses in plants, due to cell wall disruption and rupture, and exposure of PCs to heat, light, and oxygen during drying [24,25].…”

The hypoxia conditions in intensive farming systems generate oxidative stress related to oxidative damage and mortality of fish. Corn husk meal (CHM), as a source of antioxidants, might modulate the antioxidant response and prevent the damage elicited by hypoxia. This study evaluated CHM’s ability to modulate a hepatic response in Nile tilapia exposed to hypoxia. A control and a test diet supplemented with 25 g CHM/kg feed were formulated. Ninety Nile tilapias (5.09 ± 0.55 g initial weight) were fed for 36 days to evaluate growth, feed efficiency, and hepatic antioxidant response (CAT, catalase; SOD, superoxide dismutase, and GPx, glutathione peroxidase) in normal oxygen conditions (normoxia). After the feeding trial (36 days), fish were exposed to hypoxia (1.5 ± 0.2 mg/L dissolved oxygen), and the hepatic antioxidant response was determined. There was no significant effect of CHM on growth and feed efficiency. The CAT activity was significantly increased in tilapias exposed to hypoxia and fed the test diet compared to the control group exposed to hypoxia. The SOD and GPx activities were unchanged in tilapias in normoxia and hypoxia conditions. Results suggest that CHM dietary supplementation promotes the antioxidant response in Nile tilapia exposed to hypoxia through CAT modulation.
