Investigation of polyphenol profile, antioxidant activity and hepatoprotective potential of Aconogonon alpinum (All.) Schur roots

Abstract

AbstractLiver plays vital role in detoxification of exogenous and endogenous chemicals. These chemicals as well as oxidative stress may cause liver disorders. This study was aimed to evaluate the hepatoprotective effects of various fractions of Aconogonon alpinum methanolic extract against carbon tetrachloride (CCl4)-induced liver toxicity in mice. First, hepatoprotective potential of various fractions of A. alpinum was assessed and then antioxidant activity and profiling of polyphenolic compounds were assessed. A total of 78 male albino mice (BALB/c) were randomly divided into 13 groups (n = 6); Group I (normal control), Group II (CCl4 only), Group III (CCl4 + silymarin 100 mg/kg) and Groups IV–XIII (CCl4 + various fractions [200 and 400 mg/kg]). Hepatic biochemistry and liver injury were assessed by analysis of serum levels of hepatic enzymes and histopathological analysis, respectively. Results showed that polar fractions (ethyl acetate, n-butanol and aqueous fractions) exhibited highly significant (P < 0.01) reduction in increased level of liver biochemical parameters in a dose-dependent manner with consistent histopathological findings. Likewise, these fractions revealed strong antioxidant potential and polyphenolic compound contents. In conclusion, the present work has revealed promising antioxidant activity, polyphenolic profiling and potential hepatoprotective efficacy. Thus, the significant results unveil the study as a step forward towards evidence-based phytomedicine.
