NEUZA, JORGE; BRUNA, JORGE BERTANHA  y  MORENO LUZIA, DÉBORA MARIA. Antioxidant Activity and Profile Fatty Acids of Jabuticaba Seeds (Myrciaria cauliflora Berg). Acta biol.Colomb. [online]. 2011, vol.16, n.2, pp.75-82. ISSN 0120-548X.

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 ºC 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.
