摘要：Preliminary phytochemical screening of Borreria verticillata species of Sudano-Sahelian savanna and the effect of aqueous leaf extract of the plant were studied in CCL 4 -induced hepatotoxicity rats. Screening of the aqueous extract indicates the presence of alkaloids, flavonoids, tannins, glycosides, sterol and saponins. While athraquinone was absent. Serum levels of aspartate aminotransferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), total protein (TP) and bilirubin (BL) were analysed in rats intraperitoneally administered with 100 mg/kg CCl 4 followed by oral treatment with 300mg/kg of aqueous leaf extract of B. verticillata for 48 and 96hrs. The rats treated for 48 hours after had serum AST, ALT, ALP, TP and BL levels not statistically different (P>0.05) compared to both normal control and positive control (treated with 100mg/kg standard drug) although the value of positive control was slightly lower than the test values. However, the test values were statistically lower compared to toxicity control at P< 0.05. The serum AST, ALT, ALP, TP and BL levels when the treatment was extended to 96 hours showed similar pattern to 48 hours treatment. Even though the test values with respect to the enzymes activity were slightly lower in the extended treatment. This result indicates the hepatocurative properties of aqueous leaf extract of B. verticillata on CCL 4 -induced hepatotoxicity rats, which could be attributed to its phytochemical contents.
