A novel hepatoprotective activity of Alangium salviifolium in mouse model

In this study, the hepatoprotective activity of methanol bark extract of Alangium salviifolium (BEA) was evaluated for biochemical and histological parameters in swiss albino mice with CCl₄-induced hepatotoxicity. The hepatomodulatory effect of two doses of BEA (20 and 50 mg/kg bw for 15 days by oral gavage) was assessed on antioxidant enzymes, phase I and phase II drug detoxifying enzymes. For the characterization of the extract, GC-MS analysis was performed that revealed the abundance of alkaloids and steroidal compounds. Total phenolic and flavonoid contents in BEA were 69.61 ± 0.18 mg GAE/g and 46.27 ± 3.44 mg Rutin/g, respectively. BEA administration decreased the levels of AST, ALT, and ALP, which were elevated due to hepatic damage by CCl₄. BEA significantly decreased the lipid peroxidation, activities of LDH, and phase I enzymes including cytochrome P450 reductase, cytochrome b5 reductase while increased the activities of SOD, CAT, and phase II enzymes DT-diaphorase and glutathione S-transferase in liver. Further, histological evaluation of the liver tissue was suggestive of the protective effect of BEA against CCl₄ toxicity. Together, these results suggest that BEA has strong hepatoprotective activity in mice which may also be attributed to its potential chemopreventive efficacy.
