“…It means that phenolic compounds present in these fruit are the major contributors to the reducing power and scavenging radical capacities. It may, therefore, be speculated that the major role of peach fruit polyphenols is that they act as potent radical scavengers and primary chain-breaking antioxidants, what was confirmed by other authors [ 19 ].…”

The presented study provides important insights on the health properties of Prunus persica fruit related to their polyphenol and carotenoid profiles, antioxidant capacity and in vitro potential to inhibit enzymes relevant to type 2 diabetes (α-amylase, α-glucosidase) and obesity (pancreatic lipase) management. Such results have not been published so far. The study showed substantial differences in the chemical composition of peach fruit depending on the cultivar. At the same time, it demonstrated some common features of selected cultivars - the varieties with light flesh (‘Spring Time’; ‘Madison’) were characterized by a high content of phenolic acids and flavonols, thus exhibiting high activity against α-amylase, while the yellow varieties with high content of carotenoids (‘Harrow Diamond’; ‘Harrow Beauty’) showed high inhibitory activity toward porcine pancreatic lipase. Finally, it has been shown that peach fruit is an interesting raw material with a varied chemical composition and nutritional value, especially with high inhibitory potential against digestive enzymes linked to obesity and type 2 diabetes, strongly determined by the cultivar.

Objective. The aim of this work is to study and compare the antioxidant properties and phenolic contents of aqueous leaf extracts of Juniperus thurifera, Juniperus oxycedrus, Juniperus Phoenicea, and Tetraclinis articulata from Morocco. Methods. Antioxidant activities of the extracts were evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging ability, Trolox equivalent antioxidant capacity (TEAC), and ferric reducing antioxidant power (FRAP) assays. Also the total phenolic and flavonoids contents of the extracts were determined spectrophotometrically. Results. All the extracts showed interesting antioxidant activities compared to the standard antioxidants (butylated hydroxytoluene (BHT), quercetin, and Trolox). The aqueous extract of Juniperus oxycedrus showed the highest antioxidant activity as measured by DPPH, TEAC, and FRAP assays with IC50 values of 17.91 ± 0.37 μg/mL, 19.80 ± 0.55 μg/mL, and 24.23 ± 0.07 μg/mL, respectively. The strong correlation observed between antioxidant capacities and their total phenolic contents indicated that phenolic compounds were a major contributor to antioxidant properties of these plants extracts. Conclusion. These results suggest that the aqueous extracts of Juniperus thurifera, Juniperus oxycedrus, Juniperus phoenicea, and Tetraclinis articulata can constitute a promising new source of natural compounds with antioxidants ability.

“…The radical scavenging activity was investigated by2,2diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and 2,2'-azinobis (3-etilbenzotiazolin-6-sulfonic acid) ABTS assay. For DPPH analysis the procedure previously reported was applied Loizzo et al (2015). The DPPH test is based on measurement of the scavenging capacity of antioxidants towards DPPH radical.…”

Extra virgin olive oil (EVOO) plays a crucial role in the Mediterranean diet. Recently, attention has been focused on presence in EVOO of phenolic compounds, phytochemicals characterized by a series of healthy properties. This paper analyzed the phenolic profile, the inhibitory activity against carbohydrate hydrolising enzyme as well as the radical scavenging activity of EVOO obtained from Olea europea L. cv. Frantoio. Samples derived from fruits collected in four different areas: Cariati, Vaccarizzo Albanese, Montalto Uffugo, and Praia a Mare. The phenolic profile obtained by HPLC revealed the presence of hydroxytyrosol (3,4-DHPEA, between 1.2 and 5.3 mg/kg) and p-hydroxyphenylethanol or tyrosol (p-HPEA, between 1.1 and 5.4 mg/kg), as the main components. Secoiridoids and their derivatives were also found in high concentrations (3,4-DHPEA-EDA 50.3-98.4 mg/kg, p-HPEA-EDA 34.6-52.9 mg/kg). All samples showed carbohydrate-hydrolyzing enzymes inhibition. The most promising activity was observed with EVOO from Vaccarizzo Albanese (IC50 of 65.5 and 57.7 µg/ml against α-glucosidase and α-amylase, respectively). The same sample showed the highest antioxidant activity of 45.3 and 56.3 µg/ml against DPPH and ABTS radicals, respectively. This sample was richest in phenols. In conclusion, EVOO has high-level bioactive compounds and a promising antioxidant and hypoglycemic activity.
