Ruta chalepensis L. (Rutaceae) leaf extract: chemical composition, antioxidant and hypoglicaemic activities.

2017

Ruta chalepensis L. (Rutaceae) leaf extract was investigated for its chemical profile and antioxidant and hypoglycaemic properties. The antioxidant effects were investigated by 2,2-diphenyl-1-picrylhydrazyl (DPPH), Chi-carotene bleaching, and metal chelating activity assays. The carbohydrate-hydrolysing enzymes inhibition assay was used to test the hypoglycaemic potential. R. chalepensis showed a high content of hesperidin and rutin with values of 591.9 and 266.7 mg/g dry extract, respectively. The extract exhibited a promising protection of lipid peroxidation (IC50 value of 16.9 mu g/mL) and inhibited both alpha-amylase and alpha-glucosidase enzymes in a concentration-dependent manner. The…

Comparative Chemical Composition and Bioactivity of Opuntia ficus‐indica Sanguigna and Surfarina Seed Oils Obtained by Traditional and Ultrasound‐Ass…

2018

This study investigates the seed oils obtained from two different varieties of Opuntia ficus-indica (Sanguigna and Surfarina) growing in Sicily, Italy. Soxhlet and ultrasound-assisted extraction procedures are used to obtain the seed oils. The fatty acid profile, γ-tocopherols, carotenoid content, and the bioactivity in terms of the antioxidant effects (using ABTS, DPPH, FRAP, and β-carotene bleaching tests), and carbohydrate-hydrolysing enzyme inhibitory activity (α-amylase and α-glucosidase) are determined. The extraction procedure does not significantly affect the fatty acid composition of the oil, but it does affect the tocopherol and carotenoid contents, as well as the antioxidant and …

High-Performance Liquid Chromatography/Electrospray Ionization Tandem Mass Spectrometry (HPLC-ESI-MSn) Analysis and Bioactivity Useful for Prevention…

2019

This study aimed at evaluating and comparing the chemical profile obtained by HPLC-ESI-MSn analysis, the inhibitory activity of enzymes linked to obesity (α-amylase, α-glucosidase, and lipase) and the antioxidant properties (DPPH, ABTS, FRAP, and β-carotene bleaching tests) of ethanol extracts of bulbs (BE) and aerial parts (APE) from Allium commutatum Guss. (known in Italy as “aglio delle isole”). The chemical profile revealed alliin as the main abundant compound with values of 31.5 and 38.8 mg/g extract for BE and APE, respectively. APE is rich also in quercetin (38.5 mg/g extract) and luteolin (31.8 mg/g extract). Bulbs extract exhibited the highest activity as inhibitor of enzymes linke…
