          Abstract

          This work has the objective a survey of the species of plants and their uses as medicinal, which are utilized for therapeutic purposes in Northeast region of Brazil. The area of study is recognized by a rich diversity of species of plants and habitats that ranges from Rainforest, Atlantic Forest, coastal dunes systems and mangroves, to dry forests and savannas. As results, a total of 650 species belonging to 407 genera and 111 families were recorded and also their ethnomedicinal information. The floristic diversity is dominated by higher plants and only five species belonging to the families Aspleniaceae, Cyatheaceae, Equisetaceae, Polypodiaceae and Selaginellaceae were reported belonging to the Ferns group, which correspond to less than 1 % of the total of the registered species. This study aims at emphasizing the greatest importance of investigation of those species that have not been subject of pharmacological study, although their popular uses have already been reported.

          Este trabalho teve como objetivo um levantamento das plantas e dos seus usos como medicinais, as quais são utilizadas com fins terapêuticos na região Nordeste do Brasil. A área de estudo é reconhecida por uma rica biodiversidade, principalmente de plantas e de hábitats, abrangendo desde a Floresta Amazônica, Floresta Atlântica, sistemas de mangues e dunas costeiras, até florestas secas e savanas. Como resultados, foram registrados um total de 650 espécies pertencentes a 407 gêneros e 111 famílias, e suas informações etnomedicinais. A diversidade florística é dominada por vegetais superiores e apenas cinco espécies das famílias Aspleniaceae, Cyatheaceae, Equisetaceae, Polypodiaceae e Selaginellaceae pertencem ao grupo das Pteridófitas, que corresconde a menos que 1% do total das espécies registradas. Este estudo sugere a grande importância da investigação das espécies farmacologicamente ainda não estudadas, uma vez que seus usos populares estão registrados.

              Mosquitocidal activities of octacosane from Moschosma polystachyum Linn (lamiaceae).

              The toxicity of the plant Moschosma polystachyum was evaluated against mosquito Culex quinquefasciatus. The crude leaf extract and active compound octacosane showed negligible mortality against early third instar larvae of Culex quinquefasciatus. The 24 h LC(50) value was observed at 153.2+/-1.3 mg/l and 7.2+/-1.7 mg/l for crude leaf extract and active compound octacosane, respectively. The repellent activity of active compound octacosane at 1.0 and 2.5 mg/cm(2) concentration gave 85.2+/-1.7 min and 54.6+/-2.3 min protection, respectively. The total percentage protection of octacosane was 96.2+/-0.9 at 2.5 mg/cm(2) and 86.4+/-1.3 at 1.0 mg/cm(2) concentration.
