“…Medicinally they are used for antinociceptive, anti-inflammatory, antisyphilitic and healing action (Barbalho et al 2016;Duarte & Hayashi, 2005;Rosa & Souza, 2003;Sartor et al, 2010;Silva & Fonseca, 2016;Silva Júnior et al, 2010). The extract of the essential oil of the species presents efficient results in the antimicrobial potential in a wide spectrum (Do Carmo Pimenta et al, 2020;Souza et al, 2016).…”

This work aimed to evaluate the influence of dry and wet heat processing on the antioxidant profile and antioxidant activity in ora-pro-nobis leaves. The leaves were collected, washed, and separated into three groups for the treatments: application of moist heat (hydrothermal cooking at 100 ºC / 4 minutes), application of dry heat (70 ºC / 8 hours), and control (raw material). The characteristics were evaluated: total soluble solids (SST), total solids (ST), pH, phenolic compounds (CPT), flavonoids (FT), anthocyanins (AT), antioxidant activity (AA). To identify the chemical profile and the chemical profile, fingerprints were obtained using PS / MS paper spray. The content of SST and ST decreased with moist heat. The CFT content increased with wet heat (12.43 ± 0.98) and decreased with dry heat (4.25 ± 0.93 g EAG 100 g-1). There was a decrease in the FT and AT content in the leaves processed with dry heat (132.67 ± 20.28 mg 100 g-1 and 19.70 ± 3.34 mg CG 100 g-1, respectively). AA decreased in both processes, which was higher in ora-pro-nobis leaves processed with dry heat (0.82 ± 0.0033 µmol ET g-1). 26 phenolic compounds were identified in the ora-pro-nob leaves by paper spray. The chemical profile, except for the substances 4,5-dimethyl-2,6-octadiene and methyl ester linolenic acid was not affected by thermal processing. Knowing the effect of food processing is important to understand the behavior of compounds that act beneficially on human health.

“…The preparation was apparently successful in terms of its physical properties, but no attempts have been reported so far at testing its efficacy in biological terms. An attempt at exploring the antimicrobial properties of the ora-pro-nobis essential oils has also been reported [112]. In this work, the antimicrobial capacity of the essential oils against microorganisms commonly found in the coats of health professionals was investigated.…”

Pereskia aculeata Miller and Pereskia grandfolia Haw, known as ‘ora-pro-nobis’, are unconventional vegetables belonging to the Cactaceae family, native to the Americas and common in the northeast and southeast regions of Brazil. This review attempts to present a balanced account of both the methods used for obtaining extracts from the diverse parts of the plants and the results that were obtained in terms of their applicability to foods and other products with biological activities. Attention will also be devoted to the properties of their bioactives and their applications to real food products. Methods for obtaining extracts from the diverse parts of the plants will be analyzed, as well as the chemical nature of the bioactives that were hitherto identified. Next, the applicability of ora-pro-nobis in either its integral form or in the form of extracts or other products (mucilages) to the production of food and dietary supplements will be analyzed. The species have been extensively investigated during the last few decades. But, the determination of chemical structures is frequently incomplete and there is a need for new studies on texture determination and color evaluation. Further studies exploring the fruit and flowers of P. aculeata are also required.

A espécie Pereskiaaculeata, conhecida popularmente como ora-pro-nóbis pertence à família das Cactaceae, e é encontrada em regiões áridas ou levemente áridas, como por exemplo Caatinga, Cerrado e Mata Atlântica. É amplamente utilizada na alimentação devido ao seu alto teor nutricional em proteínas, vitaminas, aminoácidos essenciais, além de ser rica em compostos fenólicos, apresentando atividade antioxidante, antibacteriana, antifúngica e cicatrizante. Esse trabalho teve como objetivo avaliar a morfologia, anatomia e a presença de compostos fenólicos em amostras de plantas cultivadas e conhecidas como sendo da espécie P. aculeata, para contribuir para o processo de identificação da planta. Suas folhas são simples, com formato elíptico a lanceolado, planas, base cuneada, carnosas e glabras, com coloração verde escura. Na lâmina foliar apresenta epiderme uniestratificada, parênquima paliçádico e esponjoso, estômatos paracíticos, anfiestomáticos, cristais de oxalato de cálcio, células de mucilagem. Seu caule temcaracterística cilíndrica, bem desenvolvida, lenhoso, com epiderme uniestratificada, xilema e floema. Nos testes de taninos foi observada a precipitação nas reações e nos testes de antraquinonas pode-se observar a turvação, dados que indicam a presença desses compostos. O estudo morfoanatômico de folha e caule realizados contribuem no processo de identificação, porém, mais ensaios são necessários, além de uma exsicata para a correta determinação de que a planta utilizada é realmente a P. aculeata.
