“…The 60% ethanolic leaf extract of C. erectus exhibited highest in-vitro antioxidant activities. The βcarotene bleaching based antioxidant potential of 60% ethanolic extract was much higher than recently reported inhibition percentage of 17.88±3.13 for ethanolic extract of Bromelia laciniosa (de Oliveira-Júnior et al, 2017). The elevated concentrations of extracts exhibited high antioxidant potential which might be due to higher contents of bioactive constituents mainly phenolic and flavonoids, generally responsible for antioxidant, antiradical and antidiabetic properties of plants (Raza et al, 2013;Evary et al, 2018).…”

The current study was conducted to evaluate the antioxidant, Fe-chelating and lipase inhibition activities of hydroethanolic leaf extracts of Conocarpus erectus. The proton magnetic resonance spectroscopy (1H-NMR) was used to identify the major types of primary and secondary metabolites in extract. The 60% ethanolic extract was found to be the most effective fraction regarding antioxidant, Fe chelating and lipase inhibitory properties. The 60% ethanolic leaf extract exhibited total antioxidant power of 223.0±3.27 mg ASE/g PE, β-carotene bleaching inhibition of 81.39±2.11%, Fe-chelating of 68.21±1.17% and pancreatic lipase inhibition of 50.60±1.47%, respectively. The 1H-NMR -based prediction of metabolites provided the information for presence of polyphenolic secondary metabolites and organic acids which might be responsible for the biological activities of extract. These findings of this work may be extended for metabolite characterization, in vivo trials and toxicity determination to get benefits for functional food development with antioxidative and antiobesity attributes.

Caralluma flava is a perennial, succulent edible plant distributed in the hillsides of the United Arab Emirates. In order to validate its use in the traditional system as an edible and medicinal source, we evaluated the antioxidant and in vitro free-radical-scavenging properties of its ethanol extract. The antioxidant activity of the extract was evaluated in vitro by 2,2'-azino-bis-3-ethylbenzothiazoline-6sulfonic acid (ABTS + ), 2,2-diphenyl-1-picrylhydrazyl radical (DPPH), hydroxyl radical and nitric oxide radical scavenging assays. The antioxidant enzyme activities (superoxide dismutase, catalase and glutathione peroxidase) and non-enzymatic antioxidant contents (total reduced glutathione, and Vitamin E and Vitamin C) in the extracts were also determined. The total phenolics content of the plant extract was 10.14 mg/g and the flavonoid content was 4.13 mg/g. The results showed a positive linear correlation between these phytochemicals and the free-radical-scavenging activities. The C. flava extract exhibited significant radical-scavenging properties in the ABTS( + ), DPPH( ), hydroxyl radical and nitric oxide radical assays. The study revealed that C. flava could be considered an excellent source of enzymatic and non-enzymatic antioxidants. The results indicate that the plant extract has potent free-radical-scavenging activity and ability to prevent radical chain reactions. Based on the results obtained, C. flava seems to be a very promising species for further investigation in order to identify the compounds responsible for its biological activity.

This paper describes a little of the history of the Center for Studies and Research of Medicinal Plants (NEPLAME) of the Federal University of the São Francisco Valley (UNIVASF), which is confused with the history of the Symposium of Medicinal Plants of the São Francisco Valley (PLAMEVASF). NEPLAME was created together with the first edition of PLAMEVASF on November 15, 2007, and since then we have contributed to the chemical and pharmacological study of medicinal plants in the Caatinga biome. Besides the research, we have developed several extension activities, giving back to the population the knowledge produced in our university. We also highlight the training of human resources at undergraduate and postgraduate levels and a relevant scientific production, with the Caatinga biome being the main object of study. We hope to continue this important work and reinforce increasingly the partnership between university, society and Brazilian research funding agencies.
