The objective of this study was to screen the<jats:italic>in vitro<\/jats:italic>antioxidant and hepatoprotective activity of the stem bark extracts against CCl<jats:sub>4<\/jats:sub>-induced liver damage in rats. Among different stem bark extracts tested, the ethanol extract (DSE) has shown significant<jats:italic>in vitro<\/jats:italic>antioxidant property in radicals scavenging, metal chelating, and lipid peroxidation inhibition assays. HPLC analysis of the DSE revealed the presence of known antioxidant molecules, namely, gallic acid, ellagic acid, coumaric acid, quercetin, and rutin. Bioassay-guided fractionation of DSE has resulted in the isolation and characterization of quercetin. DSE and quercetin have shown significant prophylactic effects by restoring the liver function markers (AST, ALT, ALP, serum bilirubin, and total protein) and antioxidant enzymes (SOD, CAT, GPx, and GST). These results were proved to be hepatoprotective at par with silymarin and well supported by the histological observations of liver sections with distinct hepatic cells, and mild degree of fatty change and necrosis. The results indicated that the DSE and quercetin were significant for prophylactic activity against CCl<jats:sub>4<\/jats:sub>-induced liver damage in rats. This activity could be attributed to the antioxidant constituents in the DSE and hence justified the ethnomedicinal claims.<\/jats:p>","DOI":"10.1155\/2014\/507851","type":"journal-article","created":{"date-parts":[[2014,6,2]],"date-time":"2014-06-02T18:51:27Z","timestamp":1401735087000},"page":"1-14","source":"Crossref","is-referenced-by-count":24,"title":["Antioxidant
