Evaluation of the hepatoprotective activity of hydroalcoholic extract of Alhagi camelorum against valproic acid-induced hepatotoxicity in rats.

Abstract

Despite many liver disorders, clinically useful drugs are scarce. Moreover, the available therapies are facing the challenges of efficacy and safety. Alhagi camelorum has been used in folk medicine globally for millennia to treat several ailments. Alhagi camelorum (Ac) is an old plant with a significant therapeutic value throughout Africa, Asia, and Latin America. Our goal was to determine the hepatoprotective activity of Alhagi camelorum against valproic acid induced hepatotoxicity using an animal model. The animals were segregated in 4-groups (6 male rats each) weighing 250-290g. Group-1 animals were treated with normal saline, Group-2 animals were treated with VPA at the dose of 500mg/kg i.p for 14 days consecutively, while Group-3 and 4 were treated with valproic acid (VPA) at the dose of 500mg/kg i.p for 14 days along with 400mg/kg and 600mg/kg of Ac hydroalcoholic extract respectively. Subsequently, blood serum samples and liver tissues were collected for biochemical and histopathological analysis. Phytochemical screening was carried out to screen for phytochemical classes and HPLC analysis was conducted to screen polyphenols. The antioxidant activity was carried by different assays such as DPPH, SOD, NO etc. KEY RESULTS: The administration of Ac showed hepatoprotection at the doses of 400 and 600mg/kg. Ac significantly reduces the elevated serum levels of liver biomarkers compared to the valproic acid-induced hepatotoxic group. These findings were confirmed with histopathological changes where Ac was capable of reversing the toxic effects of valproic acid on liver cells CONCLUSION: It is concluded that Ac showed significant hepatoprotective effects at different doses in the animal model used in this study.
