Pereskia violacea, a novel species of Ora-pro-nobis, is a PANC native and endemic to the Brazilian Atlantic Forest, with no prior published reports. Recognizing the importance of fruits and vegetables in a healthy diet, this study aimed to conduct the nutritional and antioxidant characterization of Ora-pro-nobis violacea leaves cultivated in the Amazon region (Brazil) and assesses the impact of seasonality on their composition. For that purpose, proximate composition, mineral and saccharides content determination, total phenolic compounds, DPPH and ORAC antioxidant capacity assays, as well as NAD+ precursors determination by HPLC were performed. Samples from the lower precipitation period (November) exhibited significantly higher results, consistent with its classification as a species belonging to the Cactaceae family. However, samples from both the rainier season (March) and the drier season (November) showed high content of protein, fiber, potassium, calcium, and iron. Total phenolic compounds content was 769.3 and 1043.6 mu g GAE/g (in dry weight), respectively, which was significantly correlated with antioxidant capacity. Furthermore, the NAD+ precursor NMN was detected at levels ranging from 6.99 to 7.24 mu g/g in fresh samples and 29.50 to 45.97 mu g/g in freeze-dried samples. This study reveals new frontiers of Pereskia violacea as a nutritious Brazilian native PANC, emphasizing the importance of valuing, cultivating, and consuming these non-conventional food plants. Furthermore, it highlights their potential as a sustainable source of nutraceuticals and promising food ingredients, suitable for enriching various food products, including the plant-based options, which have an increasingly growing demand.
