Santos, Cintia Miranda; Campos, Jaqueline Ferreira; Santos, Jaqueline Freitas dos; Balestieri, José Benedito Perrella; Silva, Denise BrentanStingless bees produce geopropolis, which is popularly described for its medicinal properties, but for which few scientific studies have demonstrated pharmacological effects. The objective of this study was to investigate the chemical composition of the geopropolis of Melipona quadrifasciata anthidioides and to evaluate its antioxidant, antimutagenic, anti-inflammatory, and antimicrobial activities. The composi...
The Chemical Profile of Senna velutina Leaves and Their Antioxidant and Cytotox...
Campos, Jaqueline Ferreira; Castro, David Tsuyoshi Hiramatsu; Damião, Marcio José; Torquato, Heron F. Vieira; Paredes-Gamero, Edgar JulianNatural products can be a source of biomolecules with antioxidant activity which are able to prevent oxidative stress-induced diseases and show antitumor activity, making them important sources of new anticancer drug prototypes. In this context, this study aimed to analyze the chemical composition of an ethanol extract of Senna velutina leaves and to assess its antioxidant and cytotoxic activities in leukemic c...
