Santos2, Joana Pacheco2 and Domitília Marques2 1 Universidade de Aveiro, Departamento de Química, CICECO, Portugal 2 INUAF, Centro de Investigação em Ciências do Ambiente e Empresariais, Portugal Reserva Natural do Sapal de Castro Marim e Vila Real de Santo António (RNSCMVRSA) is a natural reserve (SE of Portugal, Algarve region) that has habitats with different saline conditions and great ecological importance. Halophytes are plants that grow in a wide variety of saline habitats, namely in RNSCMVRSA, and can accumulated in their biomass high contents of salt. This plant behavior can increase production of reactive oxygen species (ROS) and consequently, the oxidative stress, cellular damage and metabolic disorders. In order to protect the cells from ROS, these plants developed an efficient antioxidant system. This system can be constituted by phenolics compounds that have an important effect on oxidative, anti-inflammatory and microbial stability important properties for food, dietary and pharmaceutical industries. Therefore, this work aims to identify the phenolic compounds in biomass of different autochthones halophytes species growing on natural conditions in RNSCMVSRA. Composite samples of Salicornia patula, Salicornia ramosissima, Sarcoccornia fruticosa and Sarcocornia perennis were collected in 2013. Sequential extraction was realized: firstly the plant samples were subjected to soxhlet extraction using dichloromethane and then by a solid-liquid extraction with ethanol. Finally, the main compounds present in each extract were identified by GC-MS (Gas chromatography–mass spectrometry). The total of phenolic compounds and polyphenolic antioxidants in the extracts was also determined by Folin-Ciocalteu method.
