The objective of the present work was the synthesis of 2-(2, 3, 4, & 5 substituted phenyl) 3-hydroxy-4H-Chromen-4-one and evaluation of in-vivo Hepatoprotective activity. Based on this a new series of compound had been planned to synthesize by reacting 2-hydroxy acetophenone and various aromatic aldehydes in the presence of potassium hydroxide, methanol and 30% hydrogen peroxide. The synthesized compounds were characterized by IR, NMR, and Mass spectroscopy. The in-vivo Hepatoprotective

The results displayed that the elevated levels of SGOT, SGPT, ALP and Serum bilirubin were mainly due to CCl4 intoxication, reduced significantly (*P<0.05) in rats, after treatment with synthesized compounds. Treatment at a dose of 200 mg/kg b.w. decreased the SGOT, SGPT, ALP, Serum Bilirubin levels by 8.20% ns(non significantly), 29.96%, 9.79%, and 10.11%ns (non significantly) respectively, while a higher dose of 400 mg/kg b. wt. was more effective, causing a reduction of 26.31%, 44.75%, 27.06%, and 27.85%. Silymarin used as standard drug showed a reduction of 56.09%, 69.89%, 57.46% and 35.04% receiving CCl4 alone. So depending upon the experimental data it was confirmed that the biochemical parameters of the group treated with compounds were significantly lower than the CCl4 treated group. Moreover the treatment with the synthesized compounds significantly reduced the previously raised levels of AST, ALT, ALP and bilirubin in hepatotoxic rats. Histopathological investigation had shown that at both doses (200 mg/kg b.w. and 400 mg/kg b.w.) the synthesized compounds were possessed moderate to good hepatoprotective activity, but at 400 mg/kg b.w. executed excellent hepatoprotective activity against CCl4 induced damaged hepatocytes.
