Despite a large number of liver disorders, clinically useful drugs are scarce. Moreover, the available therapies are facing the challenges of efficacy and safety. Commipohora mukul has been used in folk medicine globally for millennia for the treatment of several ailments. The current study was designed to evaluate the possible hepatoprotective activity of Myrrhanone B (MN) and Myrrhanol B (ML) isolated from C. mukul using an animal model. The animals (Swiss albino mice) were segregated into seven groups, each comprising six mice. The first group was treated with normal saline at a dose of 1 ML/kg daily intraperitoneally (i.p.) for one week. The second group was treated with acetaminophen (APAP) (250 mg/kg, i.p.), it was taken as a negative control. Group 3 was used as a positive control (treated with Silymarin (100 mg/kg, i.p.)). While groups 4-7 were used as experimental groups (termed as groups II to IV), which were treated with ML and MN at a dose of 0.6 mg/kg, and 1.2 mg/kg (i.p.) for one week. Subsequently, blood serum and liver tissue samples were collected for biochemical and histopathological analysis. Both compounds significantly improved the levels of liver biomarkers including aspartate transaminase (AST), alkaline phosphatase (ALP), bilirubin, lactate dehydrogenase (LDH), and alanine transaminase (ALT) as compared to the normal saline-treated group in APAP-induced hepatotoxic mice. Moreover, both compounds significantly modulated the expression of oxidative biomarkers including superoxide dismutase (SOD), reduced glutathione (GSH), and catalase (CAT) at the same doses. Additionally, ML and MN showed a remarkable improvement in histological changes with only mild inflammation, mild hemorrhage, no necrosis, and no pyknosis as compared to the control groups. In conclusion, MN and ML exhibited significant hepatoprotective effects in the animal model used in this study., (Copyright © 2021. Published by Elsevier Masson SAS.)
