Introduction:The present work reported the antioxidant and chemical screening of Brazilian plant aqueous and organic extracts. Methods: An amount of 895 Brazilian Amazon aqueous and organic plant extracts were tested in thin layer chromatography plates (TLC) using 2, 2-diphenyl-1-picrylhydrazyl (DPPH), β-carotene, Dragendorff's reagent, Kedde's reagent, and KOH reagent so as to evaluate antioxidant activity and chemical profiles. Antioxidant and DPPH free radical scavenging activities results were submitted to chi-square analyses. Results: Only 8.60% of the extracts showed β-carotene/bleaching response, while 96.09% of the extracts responded as a radical scavenger, alkaloids occurred in 8.0% of the extracts whereas anthraquinones occurred in 0.89% of the extracts and cardenolides in 3.89% of the extracts. Conclusion: Present findings described that Amazon plant extracts have a huge potential to be a source of antioxidant compounds to be used in preventive medicine, as well as the chemical screening revealed that their plants can be strategically assessed as a source of alkaloids to be tested in further biological assays.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
