Objective: The aim of the study was to evaluate the hepatoprotective activity of the bark extract (Ethanol: Water) in the ratio of (3:1) of Rhizophora mucronata (BERM) by intoxicating the $HepG_2$ cell lines with different toxicants viz, $CCL_4$, Ethanol and Paracetamol with different concentrations of the extract were used. The $HepG_2$ cell lines were subjected to MTT Assay for studying the cytotoxicity. Methods: $HepG_2$ cells were plated using 96 well plate in 10% bovine serum, exposed to different toxicants viz, 2% $CCl_4$, 60% Ethanol and 14 mM Paracetamol respectively. The various test concentrations (18.85, 37.5, 75, 150 and $300{\mu}g/ml$) of bark extract of Rhizophora mucronata was added and incubated for 24 hours. Medium was removed after incubation period and 0.5 mg/ml MTT(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) was added and again incubated for 4 hours at 37oC. Then MTT was removed the crystals was dissolved in DMSO and absorbance was measured at 570 nm. Results: The result showed that dose dependent increase in percentage of viability at the doses of 18.85, 37.5, 75, 150, $300{\mu}g/ml$. Te results for the $CCl_4$ intoxicated, at $300{\mu}g/ml$ of the concentration of the extract, the % of viable cells was found out to be 99.6%, for Ethanol intoxicated, 97.67%, and Paracetamol induced, 75.37%, IC50 was $21.53{\mu}g/ml$, $12.61{\mu}g/ml$ and $21.42{\mu}g/ml$ respectively. Conclusion: Thus, we conclude that, the extract possesses defensive effect against different toxicants and can be used as an alternate drug for hepatotoxicity.
