Toxicological evaluation and polyphenols characterization of pterospartum tride...
Ferreira, Fernanda M.; Peixoto, Francisco P.; Pereira, Olívia R.; Dinis, Lia Tânia; Domingues, Maria R.M.; Palmeira, Carlos M.; Cardoso, Susana M.Pterospartum tridentatum Willk. (prickled broom) is a common autochthonous plant in Portugal. Leaves and stems are normally used in cooking, to flavour rice, roast meat or hunting animals. Leaves are also used as a condiment in fresh salads and, despite of its traditional use, no toxicological evaluation has been performed. P. tridentatum leaves aqueous extract ESI-MS spectrum revealed the presence of several l...
Potential noxious effect of mentha aquatica L. on mitochondrial bioenergetics
Ferreira, Fernanda M.; Pereira, Olívia R.; Cardoso, Susana M.; Oliveira, Paulo J.; Moreno, António J.M.Mentha aquatica (water mint) extracts are regularly used in food flavoring and pharmacology. In the present study, the possible effects of an ethanolic extract from leaves of M. aquatica L. on rat liver mitochondria bioenergetics were evaluated. The plant extract (up to 25 µg.mg protein-1) but not the vehicle, inhibited the mitochondrial oxidative system, as seen by a depression of respiration (state 3, respira...

Mentha aquatica L. extract effects on mitochondrial bioenergetics
Ferreira, Fernanda M.; Pereira, Olívia R.; Cardoso, Susana M.; Oliveira, Paulo J.; Moreno, António J.M.Mentha aquatica (water mint) extracts are regularly used in food flavoring and pharmacology. In the present study, the possible effects of an ethanolic extract from leaves of M. aquatica L. on rat liver mitochondria bioenergetics were evaluated. The plant extract (25 μg•mg protein− 1) but not the vehicle, inhibited the mitochondrial oxidative system, as seen by a depression of respiration (state 3, respiratory ...
Antioxidant activity assessment in fruit liquors and spirits: methods comparison
Santos, Carolina; Botelho, Goreti; Caldeira, Ilda; Torres, Amílcar; Ferreira, Fernanda M.During the last few years, Portugal has seen an increasing trend in the development of new fruit-based products, such as liquors and spirits. The antioxidant capacity of fruit liquors and spirits, sourced commercially or produced on a pilot-scale, was assessed using two simple spectrophotometric methods: the 2,2’-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH)...
Mentha aquatica L. extract effects on mitochondrial bioenergetics

In the present study, the possible effects of an ethanolic extract from leaves of M. aquatica L. on rat liver mitochondria bioenergetics were evaluated. The plant extract (25 μg·mg protein−1) but not the vehicle, inhibited the mitochondrial oxidative system, as seen by a depression of respiration (state 3, respiratory c...

Mentha aquatica L. extract affects mitochondrial bioenergetics
Ferreira, Fernanda M.; Pereira, Olívia R.; Cardoso, Susana M.; Oliveira, Paulo J.; Moreno, António J.M.Mentha aquatica extracts are commonly used in food flavoring and pharmacology. In the present work, we evaluated the possible effects of Mentha aquatica L. (water mint) ethanolic extract on rat liver mitochondria bioenergetics. Rat liver mitochondria were isolated using conventional protocols. M. aquatica extracts were evaluated on mitochondrial membrane electric potential by using a tetraphenylphosphonium cati...
