Actividad antioxidante y perfil de ácidos grasos de las semillas de jabuticaba (Myrciaria cauliflora Berg)

Numerous natural compounds found in fruits, grains and vegetables have antioxidant activity. This work aimed to characterize jabuticaba seeds (Myrciaria cauliflora Berg) by proximate composition, antioxidant activity and fatty acids profile of their extracted oil. To obtain the extract, the dehydrated and triturated seeds were extracted with ethyl alcohol for 30 min, at a proportion of 1:3 of seeds:ethyl alcohol, under continuous agitation, at room temperature. Afterwards, the mixture was filtered and the supernatant dehydrated at 40 °C aiming to determine, by direct weighing, the extract's dry matter yield. According to the results, the jabuticaba seeds are an important source of total carbohydrates, and also presented relevant antioxidant activity. In the jabuticaba seeds oil, a significant percentage of polyunsaturated fatty acids stood out, with linoleic and α-linolenic being the main component, essentials fatty acids.

ENDO-OLIGOPEPTIDASE-A, A PUTATIVE ENKEPHALIN-GENERATING ENZYME, IN THE VERTEBRATE RETINA

Endo-oligopeptidase A, EC 3.4.22.19, converts small enkephalin-containing peptides into the corresponding enkephalins in vitro. We investigated the presence of endooligopeptidase A in the retina and its possible colocalization with enkephalins in retinal neurons. The specific activity of endo-oligopeptidase A found in pigeon retinae (30.3 +/- 7.3 mU/mg, mean +/- standard deviation) was four times higher than in rabbit retinae (7.0 +/- 1.1 mU/mg). The enzyme activity was not modified by EDTA, but it was enhanced by dithiothreitol and inhibited by zinc and 5,5'-dithiobis(2-nitrobenzoic acid). Immunohistochemical experiments with a purified antiserum against rabbit endo-oligopeptidase A revealed labeled neurons in both the inner nuclear layer and the ganglion cell layer of pigeon and rabbit retinae. Double-labeling immunofluorescence experiments demonstrated that about 90% of neurons containing endo-oligopeptidase A-like immunoreactivity also contained [Leu5]-enkephalin-like immunoreactivity. These colocalization results may represent an important step toward the demonstration of the possible involvement of endo-oligopeptidase A in enkephalin generation in vivo.
