Caracterización comparativa de canela, cinamaldehído y kaempferol para propiedades fitoquímicas, antioxidantes y farmacológicas utilizando el modelo de ratón con estrés oxidativo inducido por acetaminofeno

Abstract

This study was aimed to explore the comparative efficacy of cinnamon bark extract, cinnamaldehyde and kaempferol against acetaminophen (APAP)-induced oxidative stress. Cinnamon bark extract, cinnamaldehyde and kaempferol were utilized for in-vivo analysis. From the results of in-vitro screening tests, cinnamon ethanolic extract was selected for in-vivo study in mouse model. For this, Balb/c albino mice were treated with cinnamon ethanolic extract (200 mg/kg), cinnamaldehyde (10 mg/kg) and kaempferol (10 mg/kg) orally for 14 days followed by single intraperitoneal administration of APAP during 8 hours. Blood and organ samples were collected for biochemical and histopathological analysis. The results showed that cinnamon bark ethanolic extract, cinnamaldehyde and kaempferol ameliorated APAP-induced oxidative stress and organ toxicity in mice. In conclusion, cinnamaldehyde and kaempferol possess comparable antioxidant potential even at 20-times less dose as compared to cinnamon bark ethanolic extract suggesting therapeutic potential in oxidative stress-related disorders.
