Lepidium sativum seed (LSS) (family: Cruciferae) has been used in traditional medicine for the treatment of jaundice, liver problems, spleen diseases and gastrointestinal disorders. It was also reported to possess antihypertensive, diuretic, anti-asthmatic, antioxidant, and anti-inflammatory activities. Attempt has been made to study hepatoprotective potential of LSS available in Saudi Arabian Market. The aim of the present study was to determine the hepatoprotective effect of ethanolic extracts of LSS against carbon tetrachloride (CCl 4 ) induced acute liver injury in rats. The bioactive compounds responsible for this activity have been analyzed by GC⿿MS. To evaluate the hepatoprotective activity, six groups ( n = 6) of rats were taken. First group was control, second was toxic and other groups received oral test solutions: 100 mg/kg silymarin, or LSS (100, 200, and 400 mg/kg), once daily for 7 consecutive days, followed by hepatotoxicity induction with CCl 4 . Blood and liver tissues were collected for biochemical, antioxidant and microscopic analyses. The bioactive constituents present in the extract were analyzed by GC⿿MS. Results showed that pretreatment with LSS and silymarin significantly reduced the level of serum alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) and bilirubin (BIL), which was increased significantly in toxic group treated with only CCl 4 . Histological analysis of liver tissues in groups pretreated with LSS and silymarin showed mild necrosis and inflammation of the hepatocytes compared to the toxic group. GC⿿MS analysis of LSS showed the presence of twelve major fatty acids including alpha-linolenic acid as a major constituent. These results indicated that LSS exerts enhance hepatoprotective activity that could be attributed towards its antioxidant activity, coupled together with the presence of anti-inflammatory compounds in LSS extract.
