ANTIOXIDANT ACTIVITY AND TOTAL PHENOL, FLAVONOID AND TANNIN CONTENTS OF Croton floribundus AND Croton urucurana

Chemical characterization, cytotoxicity, antimicrobial and antioxidant potential of Justicia pectoralis Jacq and Croton jacobinensis Baill extracts

“…Thus, the amount of phenolic found in other species of Croton was compared to the data found in this research. da Silva et al (2019) evaluated different phytochemicals in hydroalcoholic extracts of C. floribundus and C. urucurana and found a phenolic concentration equal to 9.141 and 7.997 mg AGE/100g, respectively. An average of 2.602 mg AGE/100g for the aqueous extract of C. cajucara Bentda was reported by da .…”

“…These results were 95 and 75.6%, respectively, lower than that presented by the aqueous extract evaluated in this research. Croton spp are considered a source of antioxidant compounds, being reported in the literature several studies demonstrating their free radical scavenging capacity in a dosedependent way (da Silva et al, 2019;Suresh Reddy et al, 2015;Baqueiro-Peña, Guerrero-Beltrán, 2017). For C. jacobinensis, Keerthana, Kalaivani and Sumathy (2013) reported that the ethanolic extract of C. bonplandianum leaves has good antioxidant capacity after using the DPPH radical capture method.…”

Potencial bioativo, antioxidante e antimicrobiano do extrato aquoso do processo de extração do óleo essencial de folhas de Croton blanchetianus Baill

“…Em uma abordagem das interações ecológicas entre vegetais e herbívoros, sugere-se que os teores de taninos podem diminuir a taxa de predação por tornarem os materiais vegetais impalatáveis, afastando seus predadores naturais e constituindo assim um modo de defesa [34,35]. Segundo da Silva et al (2019) [36], os taninos estão entre os compostos fenólicos presentes nos extratos vegetais que apresentam atividade antioxidante.…”
