|Abstract: ||Plants are constituted for diverse bioactive compounds that are found to be important, like antioxidants compounds that are often found in
secondary metabolite in plants and are useful in prevention of some diseases (neurodegenerative and others) and oxidative stress 
In present work we develop a set of studies for evaluation of antioxidant and toxicological properties of essential oils (EOs) and aqueous
extracts of some aromatic plants from Alentejo, namely Calamintha nepeta (L.) Savi subsp nepeta (calamint), Rosmarinus officinalis L. (rosemary)
and Foeniculum vulgare L. (fennel).
EOs were extracted from aerial parts of these plants by hydrodistillation and aquoes extracts were obtained by lyophilization of the corresponding
hydrolates . Antioxidant activities were determined by three methods: DPPH radical, -carotene/linoleic acid and reducing power
assay. Toxicity of EOs and hydrolates was carried out by the brine shrimp mortality test (LC50) and evaluation of acute toxicity (DL50) in mice.
Additionally, the serum levels of some enzymes as biomarkers of liver and kidney function (AST, ALT, ALP, -GT, creatinine and bilirubin) were
