Resumo

Jabuticaba is a native fruit from the Brazilian Atlantic Forest. The fruit is commercialized in Brazil and in the world in its fresh and processed forms due to its attractive colour and flavour. The objective of this study was to quantify the chemical properties and bioactive compounds in fruits from two jabuticaba species that have rarely been study, Pendula' (Plinia trunciflora) and Ponhema' (Plinia cauliflora). Extracts of jabuticaba fruits species Pendula' and Ponhema' were evaluated by SPME combined with GC-MS for volatile compounds. Organic acids, sugars, and ascorbic acid were determined by HPLC. Minerals were determined by ICP-OES, phenolic content, antioxidant capacity (DPPH and ORAC assay), and centesimal composition were assayed on the same jabuticabas extracts. Jabuticaba Pendula' presented higher levels of ash (4.26g100g(-1)), lipids (1.21g100g(-1)), proteins (5.07g100g(-1)), dietary fibers (29.73g100g(-1)) and minerals (1122.91mg100g(-1)). Jabuticaba Ponhema' expressed higher amounts of total monomeric anthocyanins (TMA) (0.10g100g(-1)), total flavonoids (0.08g100g(-1)) and total phenolic compounds (0.43g100g(-1)). These two species had high antioxidant capacity (5.73-9.12mmol trolox 100g(-1) by DPPH method and 23.54-71.16mmol trolox 100g(-1) by ORAC method). There were found 37 new compounds, mainly terpenes (67%), that have not been previously described in jabuticaba fruit. Jabuticaba Pendula' and Ponhema' fruits can be beneficial to the human diet and potentially serve as raw material for industrial purposes. (AU)
