Effect of the aqueous extracts of the seeds of Talisia esculenta and Sapindus saponaria on fall armyworm BABT
Santos,Wander Laizo dos; Freire,Maria das Graças M.; Bogorni,Paulo Cesar; Vendramim,José Djair; Macedo,Maria Lígia R..
The effect of aqueous extracts of Talisia esculenta (T.E.) and Sapindus saponaria (S.S.), were evaluated on the development and mortality of 8-14th day-life Spodoptera frugiperda, an important pest of maize. Corn leaves were dipped in the aqueous extracts (1% w/v) and offered as food to the caterpillars. The treated corn leaves with the extracts caused larval mortality (26.71%/T.E.; 63.3%/S.S.) and also showed effect on the larval weight (237.50 mg/T.E.; 86.65 mg/S.S.) when compared with the control (11.3% and 293.45 mg), mortality and larval weight, respectively. The electrophoresis with gelatin (0.1%) showed two very clear white areas (trypsin activity) in the caterpillars midgut of all the treatments. Only the caterpillar treated with S. saponaria...

Chemical and nutritional evaluation of kernels of bocaiuva, Acrocomia aculeata (Jacq.) Lodd. Ciênc. Tecnol. Aliment.
Hiane,Priscila A.; Baldasso,Paulo Aparecido; Marangoni,Sérgio; Macedo,Maria Lígia R..
Protein characterization and results of proximate composition and mineral analyses of fruit kernels of bocaiuva, Acrocomia aculeata (Jacq.) Lodd., are reported. The kernels presented high contents of oil (51.7%), protein (17.6%) and fiber (15.8%). The seeds´ soluble proteins were isolated according to their solubility. The main separated proteins were globulins (53.5%) and glutelins (40.0%). Moreover, the presence of low molecular mass proteases in these two fractions was shown by the SDS-PAGE method. The assays of protease-inhibitory and hemagglutinating activities showed that bocaiuva´s protein fractions were not resistant to trypsin or chymotrypsin activities and that both had low lectin content. The globulin in vitro digestibility assay resembled a...
