Estudo ficoquímico e avaliação da atividade microbiológica de algas marinhas do gênero sargassum.

Abstract

S argassum is a genus of brown seaweed Sargassacea e family represented for 150 species . In the state of Paraíba , the marine flora began to be studied from th e first decades of this century . The pub l ication of the first list of species made by Luetzelburg between 1922 and 1923 can be considered the starting point o f the investigations fhycologi in Paraíba (Carvalho, 1983). Navies macroscopic algae despite arouse the attention of the scientific commu nity for their great potential as a pr oducer chemicals for industrial , economic and medical - pharmacological interest in Brazi l, especially in the Northeast , there are few studies conducted for this purpose , our group being a pioneer in research fhytocheis try . Given the availabili ty and diversity of our biomass , it is imperative that prospective studies be carried out to identify potential compounds derived from marine macroalgae with pharma cological activity . Next we observe some pharmacological activities of al gae described in the literature, among which we can mention: alginates, florotaninos, coumarins, chromones, quinones, and terpenoids feoftinas . Studies have shown that metabolites produced by algae of the genus Sargass umtiveram biological activities, such as anticoagulant, antioxidant, analgesic and antipyretic . It is important to demonstrate that knowledge about the chemical profile may contribute to the taxonomic studies of family Sargassaceae . This work, developed at the Laboratory of Pharmacology / Graduate Program in Natural and Synthetic Bioactive P roducts and Mycology Laboratory , Department of Pharmaceutical Scie nces ( Health Sciences Center ) , Federal University of Paraíba , intended to analyze the microbial activity antimicrobial constituents of the phases and seaweed of the genus Sargassum .
