Abstract

Among the diversity of species of unconventional food plants (UFP), Pereskia aculeata Miller, popularly known as ora-pro-nóbis (OPN), is being increasingly consumed in Brazil. The aim of the present study was to evaluate the antioxidant capacity and phytochemical composition of the volatile and non-volatile fractions of OPN. The volatile fraction was isolated by hydrodistillation and solid phase extraction and characterized by GC/MS and GC/FID. Aqueous extracts obtained from the samples were evaluated for the total phenolic content (Folin-Ciocalteu) and antioxidant activity (DPPH, FRAP and ORAC). The identification of phenolic acids, flavonoids and alkaloids present in these matrices was carried out by HPLC/HRMS. A total of twenty-eight volatile compounds were identified in the samples. Hexadecanoic acid and scalene were the only compounds detected in all volatile fractions. Hexadecanoic acid, linoleic acid, oleic acid and phytol stood out quantitatively. β-linalool, α-terpineol, β-farnesene and trans-nerolidol showed potential to influence FF aroma. Regarding the non-volatile fraction, 17 compounds (phenols and alkaloids) were identified in FV and 11 compounds in FF. FF, however, showed greater antioxidant potential than fruits, which can be explained by the concentration of these compounds during the drying process of the flowers. As far as we know, this is the first study on the phytochemical profile and antioxidant activity of Pereskia aculeata Miller flowers. Unpublished data on the volatile profile of the fruits of this species is also being presented in this manuscript.
