Combining vitamin C and carotenoid biomarkers better predicts fruit and vegetable intake than individual biomarkers in dietary intervention studies.

The aim of this study was to determine whether combining potential biomarkers of fruit and vegetables is better at predicting FV intake within FV intervention studies than single biomarkers

La sorveglianza dei potenziali rischi da integratori alimentari in Europa.

Il tema della sicurezza degli integratori alimentari, troppo spesso sottovalutato è stato oggetto del workshop “Food supplements vigilance systems in a public health perspective: the European context”, tenutosi presso l’International School of Pharmacology “Giampaolo Velo” di Erice lo scorso ottobre 2022

Antioxidant properties and stability of aegle marmelos leaves extracts

Aegle marmelos (AM) leaves were extracted with methanol (ME), ethanol (EE), water (WE) and analyzed for antioxidant activities by DPPH radical scavenging method, reducing power and in vitro inhibition by Fenton's reagent-induced oxidation of lipid system. Stability of extracts to pH (4, 7 and 9) and temperature (100 °C, 15 min.) was studied. The three extracts showed varying degree of efficacy in each assay in a dose dependent manner. The inhibition of MDA formation in Linseed oil by EE (47%) was significantly (P\textless0.05) higher than WE (28%) and ME (23%) but less than α- Tocopherol (80%). WE showed maximum stability to high temperature. The antioxidant activity of EE at pH 4 was significantly higher (P\textless0.05) compared with WE and ME. At pH 7, the antioxidant activity of all the three extracts remained unchanged. Data indicates that potential exists for the utilization of Aegle marmelos as a natural antioxidant. © 2011 Association of Food Scientists & Technologists (India)
