“…This difference in lethal concentrations might be due to differences in secondary metabolites present in the plant. This was in concordance with the previous reports exploring the insecticidal activity of the phytochemicals through the dose-dependent response [ 40 ].…”

“…Podemos também elencar nesses espectros vários multipletos na região entre δH 3,0 e 5,0 ppm que é típica de hidrogênios oximetinicos ligados a carbonos oxigenados, sugerindo a presença de unidade de açúcar, compostos glicosilados, na espécie, como por exemplo, heterosideos de flavonoides. Os singletos em 4,10 e 4,12 ppm, nos permitiram inferir a possível existência de hidrogênios de grupos metoxila que também são comuns nessa classe e em compostos fenólicos como os taninos (TELES et al, 2015;FERREIRA et al, 2019). Os multipletos elencados na expansão 02 em aproximadamente δH: 3,10 e 4,27 ppm são característicos de característicos de hidrogênios oximetinicos ligados a carbonos oxigenados, indícios da presença de hidrogênios anoméricos de açúcares, como também de prótons de hidroxilas de taninos (GAIKWAD et al, 2017).…”

“…The CHCl 3 fraction underwent chromatographic and spectroscopic analysis for isolation and structural characterization of vitexin (Figure 1). Vitexin was used in the experiments described in this study, more information on the obtention procedures and structural determination is described in a previous study 2 .…”

“…The genus Waltheria (family Malvaceae) is native to both Asia, and to North, Central, and South America. Various species of this genus are used in popular medicine for antimicrobial, antitussive, and expectorant applications 2 . Various studies have identified the presence of quinoline alkaloids [3][4][5] , triterpenes, phenolic compounds, and flavonoids 6,7 being the main constituents responsible for its biological properties.…”
