Scavenging Activity on Reactive Oxygen Species with Biological Relevance by Varronia curassavica
Varronia curassavica Jacq. is a medicinal plant found in Brazil used as anti-inflammatory. Here, we investigated the in vitro antioxidant activity of 70 % ethanol extract of V. curassavica leaves on synthetic radicals (ABTS•+/DPPH•) and reactive oxygen species (O2•-, ROO•, HOCl/OCl-, H2O2), besides its in vitro cytotoxicity. The extract was characterized by UPLC-ESI-QToF-MSE and the annotated compounds were one hydroxybenzoic acid, five phenylpropanoids, and three glycosylated quercetin derivatives, being the main compound rosmarinic acid or its isomer. The antioxidant activity was very promising in all tests, highlighting on the capture of O2•-, which EC50 value was three times lower than Trolox. This activity may be due to the presence of the major compounds, all phenolic compounds. The extract also presented low cytotoxicity. Thus, the extract from V. curassavica leaves has great potential as an antioxidant.
期刊介绍:
Orbital: The Electronic Journal of Chemistry is a quarterly scientific journal published by the Institute of Chemistry of the Universidade Federal de Mato Grosso do Sul, Brazil. Original contributions (in English) are welcome, which focus on all areas of Chemistry and their interfaces with Pharmacy, Biology, and Physics. Neither authors nor readers have to pay fees. The journal has an editorial team of scientists drawn from regions throughout Brazil and world, ensuring high standards for the texts published. The following categories are available for contributions: 1. Full papers 2. Reviews 3. Papers on Education 4. History of Chemistry 5. Short communications 6. Technical notes 7. Letters to the Editor The Orbital journal also publishes a number of special issues in addition to the regular ones. The central objectives of Orbital are threefold: (i) to provide the general scientific community (at regional, Brazilian, and worldwide levels) with a formal channel for the communication and dissemination of the Chemistry-related literature output by publishing original papers based on solid research and by reporting contributions which further knowledge in the field; (ii) to provide the community with open, free access to the full content of the journal, and (iii) to constitute a valuable channel for the dissemination of Chemistry-related investigations.
