01) elevated and total protein (TP) level decreased in CCl4

treated group as compare to vehicle control group indicating liver damage. Treatment with ethanol extract of plant A. paniculata and S. chirayita at the dose of 200 mg/kg b.w. significantly (P < 0.01) reduced the SGOT, SGPT, SALP, γ-glutamate transpeptidase (GGTP). The bilirubin levels towards the normal values and increase in total protein (TP) level however the liver weight of the animals of CCl4 treated and plant extract treated groups also supports the extract activity. A. paniculata showed the more significant effect to reduce the SGOT, SGPT, SALP, γ-glutamate transpeptidase and bilirubin levels ( Table 1 and Table 2). Analysis of LPO levels was significant (P < 0.01) phosphatase inhibitor library increased in CCl4 treated animal. On learn more treatment with ethanol extract of plant A. paniculata and S. chirayita 200 mg/kg b.w. dose significantly (P < 0.01) reduced the LPO levels as compare to CCl4 treated as well as normal animal. The level of reduced GSH was significantly depleted in CCl4 treated animal group. GSH level was found to be significantly elevated towards normal level on administration of A. paniculata and S. chirayita 200 mg/kg b.w. ( Table 3). There were significant reduction in superoxide dismutase (SOD) and catalase (CAT) activities in CCl4 treated animal group and after treatment

with ethanol extract of A. paniculata and S. chirayita (200 mg/kg b.w.), significantly (P < 0.01) elevated SOD and CAT activities towards normal values were observed as compared to CCl4 treated animal group as well as vehicle the control group. Results of histopathological studies provided supportive evidence for biochemical analysis. Histology of liver section of normal animal group exhibited normal hepatic cells each with well defined cytoplasm, prominent nucleus, and nucleolus and well brought out central vein (Fig. 1a), whereas that of CCl4 intoxicated group animal showed presence of normal hepatic cords and total loss of hepatic architecture with centrilobular hepatic necrosis, fatty changes, vacuolization and congestion

of sinusoids, Kupffer cell hyperplasia, crowding of central vein and apoptosis (Fig. 1b). Treatment with standard drug Silymarin 50 mg/kg and ethanol extract of A. paniculata and S. chirayita (200 mg/kg b.w.) showed potential activity in protecting the liver cells from CCl4-injury ( Fig. 1c–e). Among these, two-plant extract, treatment with A. paniculata ethanol extract returned the injured liver to quite normal and thus shown very potential hepatoprotective activity. Liver damage induced by CCl4 is routinely used model for the screening of hepatoprotective drugs. CCl4 administration causes the acute liver damage mediated changes in liver function that ultimately leads to destruction of hepatocellular membrane.
