Resumen
TORRES PEREIRA, Maria Estella et al. Evaluation of Cytotoxicity in human red blood cells of Praxelis clematidea (Griseb.) ethanol extract. Rev. colomb. cienc. quim. farm. [online]. 2022, vol.51, n.2, pp.860-870. Epub 20-Dic-2023. ISSN 0034-7418. https://doi.org/10.15446/rcciquifa.v51n2.98326.
Introduction:
Species of the Asteraceae family are known to have aromatic, cosmetic and therapeutic properties; having several researches that evidenced medicinal potential of this family. Among the species of Asteraceae, there is Praxelis clematidea, which is rich in chemical substances such as flavonoids, terpenoids and steroids, which can perform a series of biological activities.
Aim:
To verify the toxic potential of the ethanolic extract of P. clematidea leaves against human blood cells, in order to determine the theoretical toxicity of this species.
Method:
For the performance of the cytotoxic activity test, blood suspensions of types A, B and O were prepared, which were subsequently mixed at different concentrations of the ethanolic extract for 1 (one) hour. Hemolysis was quantified by spectrophotometry at a wavelength of 540 nm.
Results:
The ethanolic extract of P. clematidea leaves in different concentrations showed low cytotoxicity against human erythrocytes in vitro, emphasizing the product as a possible viable option for the herbal medicine industry. However, it is important to clarify that more in vivo studies need to be carried out to confirm this toxicological profile of the extract.
