The Effect of Consumption of Citrus Fruit and Olive Leaf Extract on Lipid Metabolism.

Citrus fruit and olive leaves are a source of bioactive compounds such as biophenols which have been shown to ameliorate obesity-related conditions through their anti-hyperlipidemic and anti-inflammatory effect, and by regulating lipoproteins and cholesterol body levels. Citrolive™ is a commercial extract which is obtained from the combination of both citrus fruit and olive leaf extracts; hence, it is hypothesised that Citrolive™ may moderate metabolic disorders that are related to obesity and their complications. Initially, an in vitro study of the inhibition of pancreatic lipase activity was made, however, no effect was found.

Antioxidant activity comparison between [6S]-5-methyltetrahydrofolic acid calcium salt and the related racemate form.

Folates, such as [6S]-5-methyltetrahydrofolic acid, have been introduced in the market both in vitamin pills and in fortified foods. Their antioxidant activity has been evaluated, but stereoisomer influence on activity has not been proven. In this study, a comparison between [6S]-5-methyltetrahydrofolic acid (5-MTHF) and its racemate [6R,S] form was made by TEAC assay at different pHs, FRAP assay, and ORAC assay.
