“…Este apresentou resultados entre 6,8 a 7,1, sendo enquadrado na categoria de neutro. De acordo com Onofre et al (13) este valor de pH estaria dentro do normal para lodo de estação de tratamento de esgoto. A permanência deste pH é importante para manter um ambiente favorável à decomposição da matéria orgânica (14) .…”

Com o objetivo de realizar a caracterização química do lodo da estação de tratamento de efluente do município de Serra dos Aimorés - MG, e avaliar os atributos agronômicos deste, foram realizadas análises químicas dos parâmetros pH, umidade, N total, N kjeldahl, N amoniacal, N nitrato, Sólidos voláteis e totais, P total, K total, Ca total, Mg total, carbono orgânico, N/nitrito, S total e Na total. Constatou-se que o mesmo tem uso potencial para fertilização do solo. Entretanto, outros estudos devem ser realizados objetivando analisar os elementos tóxicos e patógenos para se avaliar integralmente sua composição e viabilidade para uso como fertilizante para o solo.

“…Studies performed by Onofre et al (2016) show that tarumã ( V. megapotamica ) leaves have an antioxidant potential. Similarly, powdered tarumã fruits (Figure S1B) present bioactive compounds in their extract (Figure S1C); thus, one of the ways of improving the yields of these compounds may be through the study and selection of variables on extraction process.…”

Fruits are widely used to obtain and study bioactive compounds. Among them, the tarumã (Vitex megapotamica) is still understudied. The extraction of bioactive compounds from the powdered pulp of the ripe fruit of the tarumã was studied from the selection of several variables of the extraction process through the experimental design Plackett–Burman: the pH, the solid:liquid ratio, agitation, and temperature in an extraction time of 3 h. The extracts obtained were evaluated for antioxidant activity by 2,2′‐azino‐bis‐(3‐ethylbenzothiazoline‐6‐sulfonic acid) (ABTS), 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH), and for total phenolic compounds, as well as the presence of flavonoids, anthocyanins, carotenoids, and identification of bioactive compounds was assessed by high‐performance liquid chromatography (HPLC). Using the experimental design, the best extraction condition was defined with a pH of 5, solid:liquid ratio of 1:30, stirring at 100 rpm, with a temperature of 80°C, obtaining 104.21 mg Gallic Acid Equivalent (GAE) 100 g−1 for phenolic compounds total, 742.71 μmol Trolox g−1 for ABTS, and EC50 of 2884.98 mg L−1 for DPPH. From HPLC, the presence of fumaric acid, gallic acid, p‐coumaric acid, and caffeic acid in the extracts was detected. Regarding flavonoids, anthocyanins, and carotenoids, the values obtained were 6.38 mg ECG g−1, 1.67 mg ECG g−1, and 2.89 mg 100 g−1, respectively. The selection of extraction conditions allowed obtaining better levels of bioactive compounds in the powdered pulp of tarumã extract, even with the use of water as a solvent, to avoid the presence of chemical residues in the extract, with antioxidant potential and viability for application in food products.Practical applicationsRecent research suggests a change in perspective regarding the consumption of healthier foods from plants and fruits that have important health properties. In this regard, tarumã (Vitex megapotamica) fruit has been standing out as a potential source of bioactive compounds with significant medicinal properties. The extracts obtained have a significant amount of phenolic compounds, as well as the presence of flavonoids, anthocyanins, and carotenoids, in which all of these have great potential bioactive activities. Thus, a good methodology of extraction and characterization of tarumã extract becomes a crucial part of any food, chemical, or pharmaceutical industry sector. In this regard, the present study with experimental design Plackett–Burman extraction is the way ahead due to high bioactive retention and the cost implications of the process.
