Phenolic compounds profile and main nutrients parameters of two underestimated non-conventional edible plants: Pereskia aculeata Mill. (ora-pro-n acute accent obis) and Vitex megapotamica (Spreng.) Moldenke (taruma tilde ) fruits

Non-conventional edible plants are widely present in Brazil. Several fruits of spontaneous occurrence are underestimated and scarcely used by the population. The increase in the knowledge about these plants, especially regarding the bioactive compounds present in this species, is important to increase its use, cultivation, and propagation. Ora-pro-n ' obis (Pereskia aculeata) and taruma similar to (Vitex megapotamica) fruits are two examples. In the present report, the phenolic compounds profile was determined, using liquid chromatography coupled to tandem mass spectrometry (UHPLC-ESI-MS/MS). Other assays were also performed such as protein content, fat, hu-midity, and calcium. The results show that taruma similar to fruits are rich in several phenolic compounds, especially p-coumaric acid (9.3-61.8 mg g-1), isoquercitrin (14.6-55.5 mg g-1), naringenin (7.5-30.1 mg g-1), and caffeic acid (12.7-18.3 mg g-1). Ora-pro-n ' obis fruits have showed high contents of caffeic acid (4.9 mg kg-1), rutin (3.9 mg kg-1), and hesperidin (1.7 mg kg-1), and their seeds, specifically, have showed relevant content for galangin (1.1 mg kg-1) and ferulic acid (0.3 mg kg-1).

Automated summary

Non-conventional edible plants in Brazil, such as Ora-pro-n'obis and taruma fruits, are rich in phenolic compounds and other bioactive substances. Increased knowledge about these plants can enhance their utilization, cultivation, and propagation.
