“…These compounds possess strong antioxidative, antibacterial, and antimutagenic properties. 7-hydroxycoumarin has been found to have antioxidative properties in many plants such as Fraxinus ornus and Eysenhardtia subcoriacea [29], [30]. Hu confirmed that the 7-hydroxycoumarin group could contribute to the antioxidative activity of coumarin via an electron transfer mechanism [31].…”

Fruits of Broussonetia papyrifera from South China were analyzed for their total chemical composition, and antioxidant activities in ethanol and aqueous extracts. In the fruit of this plant, the crude protein, crude fat and carbohydrates was 7.08%, 3.72% and 64.73% of dry weight, respectively. The crude protein, crude fat and carbohydrates were 15.71%, 20.51% and 36.09% of dry weight, respectively. Fatty acid and amino acid composition of the fruit were analyzed. Unsaturated fatty acid concentration was 70.6% of the total fatty acids. The percentage of the essential amino acids (EAAs) was 40.60% of the total amino acids. Furthermore, B. papyrifera fruit are rich in many mineral elements and vitamins. Total phenolic content was assessed using the Folin-Ciocalteau assay, whereas antioxidant activities were assessed by measuring the ability of the two extracts to scavenge DPPH radicals, inhibit peroxidation, and chelate ferric ions. Their reducing power was also assessed. Results indicated that the aqueous extract of B. papyrifera was a more potent reducing agent and radical-scavenger than the ethanol extract. GC–MS analysis of the ethanol extract showed the presence of some acid-containing compounds. The changes in total phenolic content and antioxidant capacity in B. papyrifera from four different regions grown under normal conditions were assessed. The antioxidant activity of different extracts was positively associated with their total phenolic content. These results suggest that the fruit of B. papyrifera could be used in dietary supplement preparations, or as a food additive, for nutritional gain, or to prevent oxidation in food products.

“…The effect of other flavonoids, such as flavanones, flavones and flavonols, has been less studied. Quercetin, kaempferol, naringenin and eriodictyol exhibit antioxidant and anti‐inflammatory effects, which confer them potential beneficial effects in preventing different inflammation‐related diseases (Narváez‐Mastache et al , ; Egert et al , ; Lou et al , ; Devi et al , ; Venkateswara et al , ). Herbacetin has been described to have anti‐hyperglycaemic and anti‐hyperlipidemic properties (Veeramani et al , ).…”

Flaxseed and soybean are an important source of phytochemical compounds, mainly lignans and isoflavones, but also of flavones, flavanones and flavonols. These compounds appear mainly glycosylated in plant food and are converted into aglycones by the intestinal microbiota, increasing their bioavailability. In this work, we analyse the ability of Bifidobacterium strains (n = 25) to produce lignan and flavonoids aglycones from flaxseed and soybean extracts. Most of the Bifidobacterium strains increased the concentrations of secoisolariciresinol, daidzein, genistein, naringenin, eriodyctiol, luteolin and apigenin. Moreover, Bifidobacterium pseudocatenulatum and Bifidobacterium breve strains showed high production of herbacetin, increased the kaempferol concentration and produced quercetin and quercetagetin. B. pseudocatenulatum INIA P815 and B. breve INIA P367 produced 32.37 AE 2.81 and 28.64 AE 3.36 mg respectively of herbacetin g À1 of lignan extract. Bifidobacterium strains transformed the glycosides of a wide range of flavonoids into their aglycones, increasing the antioxidant activity and improving their bioavailability.

“…221 Eriodictyol isolated from the aerial parts from Eysenhardtia subcoriacea was assessed using an antioxidant activity assay -guided chemical analysis, using a rat pancreas homogenate model. The isolated eriodictyol demonstrated moderate radical scavenging properties against DPPH radical 222,223 and reduced the GSH levels in rat pancreatic homogenate. 222 Furthermore, eriodictyol was assessed for its protective role against UV -induced apoptosis of human keratinocytes, the principal cell type of epidermis.…”
