Talinum paniculatum (Jacq.) Gaertn. leaves – source of nutrients, antioxidant and antibacterial potentials

Abstract

Background. The diet of most of the population is limited to a reduced number of plants, even in areas that have a varied and extensive diversity, such as Brazil. Unconventional Food Plants (UFPs) are plants considered exotic, native, and wild that grow naturally and can be used as food. Among these is Talinum paniculatum (Jacq.) Gaertn., which is widespread throughout Brazil and can be a potential source of nutrients. Due to the potential of utilization of UFPs in human food and the lack of studies regarding the composition of T. paniculatum, this study aimed to assess the nutritional value of T. paniculatum leaves, their antioxidant capacity, and their antimicrobial activity for possible use in food. Materials and methods. The characterization of the leaves of T. paniculatum was carried out through analyses of proximal composition, color, ascorbic acid, mineral profile, and antinutritional factors showing the presence of condensed and hydrolysable tannins and nitrates in low concentrations. Solvents of water, ethanol, ethanol/water, methanol, methanol/water, methanol/acetic acid and acetone/water/acetic acid were used to evaluate the extraction yield of phenolic compounds, antioxidant capacity, and antibacterial activity of the extracts. Results. High contents of protein (18.61 g 100 g -1 ), insoluble dietary fiber (34.75 g 100 g -1 ), ascorbic acid (81.03 mg 100 g -1 ), magnesium, potassium, and calcium (649.600, 411.520 and 228.117 mg 100 g -1 , respectively) were observed. Extraction using the mixture of solvents of methanol/acetic acid showed the highest yield of phenolic compounds (432.73 mg EAG 100 g -1 ) and antioxidant capacity using the DPPH assay (3144.92 mg 100 g -1 ). Bacillus cereus growth was inhibited by the T. paniculatum extracts. Conclusion. T. paniculatum leaves are a source of nutrients and their extracts have antioxidant and antibacterial potentials which can be used as supplements in food to improve one's health.

O que sabemos sobre a caracterização nutricional de plantas alimentícias não convencionais? Uma revisão sistemática

“…Desde as folhas, pecíolos, frutos, flores, botões florais, caule, haste e raízes caracterizados apresentaram um elevado teor de umidade, na faixa de 94,16% a 65,91% (Tabela 1). Porém, no estudo realizado por Menezes et al, (2021) o valor apresentado para o percentual de umidade está equivocado. De acordo com a metodologia descrita pela Association of Official Analytical Chemists, utilizada no estudo, o teor de umidade é expresso em matéria úmida e não em matéria seca, como está descrito no trabalho.…”

Javanese Ginseng Root Extract (Talinum Paniculatum (Jacq) Gaertn) to Increase Superoxide Dismutase Activities in White Male Sprague Dawley Rats by Using a Forced Swimming Test Model

“…The results of this study are supported by Kim et al on 2010, who have proven that the administration of ginseng extract could increase intracellular activities of the SOD enzyme (7) . Meanwhile, Menezes et al on 2021 suggest that Javanese ginseng extract potentially has antioxidants to counteract free radicals and superoxide radicals (8) . Other studies have also revealed that Javanese ginseng contains secondary metabolites, such as saponins, flavonoids, and tannins.…”

“…There has been researched by Kim et al on 2010, who have proven that the administration of Korean red ginseng extract can increase intracellular SOD enzyme activity 7 , and research by Menezes et al on 2021, showed that ginseng leaves extract has the potential to have antioxidants to counteract free radicals and superoxide radicals 8 . These two studies only analyzed the effect of ginseng on antioxidant potential in vitro.…”

Nephrotoxicity effect of Ginseng Bugis (Talinum paniculatum (Jacq) Gaertn) leaves ethanolic extract on creatinine, urea, and kidney histopathological features

“…The root is known to possess a tonic effect, and believed to have benefits to the body system (Santoso et al, 2016;Sulistiono et al, 2017). Ginseng leaves contain protein, magnesium, potassium, ascorbic acid, phenonugrlic, flavonoids, and iron, which provide beneficial effects (Moura et al, 2020;Menezes et al, 2021). The use of medicinal herbs or traditional medicine is assumed to be safe, but potential toxicity might occur, either at a low or high dose, during longterm usage.…”
