Estado Da Arte Da Literatura Científica Sobre Hancornia Speciosa: Tendências E Lacunas

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)The economic and scientific interest in Hancornia speciosa (mangabeira) has been growing in recent years, mainly due to the marketing of fruit and extraction of natural compounds with high pharmacological potential. In this study, a scientometric survey about mangabeira was carried out in order to promote and direct future studies on the species. As a result, low scientific productivity associated with this species was found, with only 131 articles published in the last 69 years. In addition, this study identified some trends in bibliographic production on mangabeira, among them: the increasing number of articles over the years; scientific dissemination in nationwide journals; the main focus of this study is associated with agronomic studies; the experimental approach is more frequent and usually associated with populations of restricted geographical distribution; and the scientific production is mainly from education institutions. Furthermore, this study also allowed the identification of some gaps in knowledge about mangabeira, among them the difficulty in describing and characterizing botanical lines; lack of analysis of the genetic diversity of widely distributed populations; lack of management and conservation projects for the species; lack of description of cultivation, collection and preservation techniques of fruits; and lack of identification of natural compounds responsible for its pharmacological activity. It is expected that the data generated in this study will serve to direct future studies on H. speciosa. © 2016, Sociedade Brasileira de Fruticultura.

Composição das sementes e dos óleos de semente de tabacos brasileiros

Tobacco seeds of Nicotiana tabacum L. and Nicotiana rustica L. Species were studied regarding protein and oil contents. Fatty acid composition of tobacco seed oils was determined, through as chromatography. The percentage of linoleic acid, the main fatty component, was found to lie between 65.0 and 74.3. It is reported, for the first time, the occurrence of erucic acid, in a percentage higher than trace, but only for two samples. Only with respect to the colour it was observed a difference between oils from the two species.Sementes de tabaco das espécies Nicotiana tabacum L. e Nicotiana rustica L. foram estudadas, comprovando-se seu alto teor oleaginoso. A composição dos óleos de tabaco em ácidos graxos foi examinada por cromatografia de gás, encontrando-se teores de 65,0 a 74,3% para o ácido linoléico, principal componente graxo. Relata-se, pela primeira vez, a ocorrência do ácido erúcico em quantidade maior que traços, embora apenas para duas amostras. Somente quanto à cor foi notada a diferença sensível entre os óleos das duas espécies estudadas
