Evaluation of chemical constituents in Norantea guianensis aubl. Extracts, embryotoxicity, and acetylcholinesterase inhibitory potential in Danio rerio
Norantea guianensis Aubl., commonly referred to as the parrot flower or macaw-tail vine, is a plant species found in the Brazilian Amazon, Caatinga, and Cerrado biomes. It is used in folk medicine for its anxiolytic properties, as well as its ability to alleviate headaches and reduce fever. Nevertheless, despite its therapeutic benefits, the impact on embryonic development has yet to be fully explained. The objective of this study was to evaluate chemical constituents by HPLC-DAD, UV–visible and classical phytochemistry and the LC50 of ethanolic extracts from the stem and leaves of N. guianensis in Danio rerio after 96 h and to investigate their effect on developmental morphology. The findings were then related to both Acetylcholinesterase (AChE) activity and the plant's chemical composition. Zebrafish embryos were exposed to 0, 20, 40, 60, 80 and 100 mg/L concentrations of stem and leaves extracts. Phytochemical analysis revealed that the stem extract contained predominantly phenolic compounds, tannins, and anthraquinones, while the leaf extract contained alkaloids and flavonoids. The LC50 values for the stem and leaf extracts were 64.55 mg/L and 7.16 mg/L, respectively, being the stem extract was more toxic than the leaf extract. Induced malformations and alterations in the zebrafish development in different concentrations for both extract including pericardial edema, increased heart rate, spinal malformation and equilibrium disruption. Unlike to stem extract, the leaf extract delayed larval hatching and inhibited AChE activity. The findings indicate that the leaf extract possesses higher embryotoxicity and its use should be avoided during pregnancy.
期刊介绍:
Toxicon has an open access mirror Toxicon: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. An introductory offer Toxicon: X - full waiver of the Open Access fee.
Toxicon''s "aims and scope" are to publish:
-articles containing the results of original research on problems related to toxins derived from animals, plants and microorganisms
-papers on novel findings related to the chemical, pharmacological, toxicological, and immunological properties of natural toxins
-molecular biological studies of toxins and other genes from poisonous and venomous organisms that advance understanding of the role or function of toxins
-clinical observations on poisoning and envenoming where a new therapeutic principle has been proposed or a decidedly superior clinical result has been obtained.
-material on the use of toxins as tools in studying biological processes and material on subjects related to venom and antivenom problems.
-articles on the translational application of toxins, for example as drugs and insecticides
-epidemiological studies on envenoming or poisoning, so long as they highlight a previously unrecognised medical problem or provide insight into the prevention or medical treatment of envenoming or poisoning. Retrospective surveys of hospital records, especially those lacking species identification, will not be considered for publication. Properly designed prospective community-based surveys are strongly encouraged.
-articles describing well-known activities of venoms, such as antibacterial, anticancer, and analgesic activities of arachnid venoms, without any attempt to define the mechanism of action or purify the active component, will not be considered for publication in Toxicon.
-review articles on problems related to toxinology.
To encourage the exchange of ideas, sections of the journal may be devoted to Short Communications, Letters to the Editor and activities of the affiliated societies.
