Folk medicine of trás-os-montes (Portugal). Traditional uses and bioactive compounds of six common medicinal species

Abstract

Ethnobotanical surveys conducted in north-eastern Portugal along several years (2000-2009) reported plant knowledge and use of almost 150 wild species used in folk medicine. This poster documents traditional knowledge and reports the first approach to the antioxidant potential evaluation of six of these species with particular cultural significance, Glechoma hederaceae (1), Foeniculum vulgare (2), Malva sylvestris (3), Oregano virens (4), Rosa canina (5), Thymus mastichina (6), accessed by biochemical assays used as models for the lipid peroxidation damage in biomembranes. Bioactive compounds such as phenolics, flavonoids, vitamin C and vitamin E were also determined.
