Hepatoprotective Activity of 6-Heptadecylcyclohex -3-ene-1 Carboxylic Acid Isolated from the Methanol Extract of Dichrostachys cinerea Wight & Arn. Stem Bark

Aim of the Study: The phytoconstituent 6-heptadecylcyclohex 3-ene-1 carboxylic acid isolated from the methanol extract of Dichrotachys cinerea Wight. stem bark was evaluated for hepatoprotective activity against CCl4 induced toxicity.

Materials and Methods: The constituent 6-heptadecylcyclohex 3-ene-1 carboxylic acid isolated from the methanolic extract of D. cinerea and the structure was confirmed by spectroscopic studies. Hepatoprotective property was screened in male wistar strain rats. The parameters studied were estimation of liver function serum markers such as serum total bilirubin, total protein, alanine transaminase, aspartate transaminase, alkaline phosphatase and histological profile of the liver tissue.

Results: The LD50 of methanolic extract and constituent, 6-Heptadecylcyclohex -3-ene-1 carboxylic acid were evaluated and found to be 500 and 100 mg/kg body weight respectively. The hepatoprotective activity of constituent was more significant as similar to the standard hepatoprotective drug silymarin. The histological profile of the liver tissue showed the presence of normal hepatic cords, absence of necrosis and fatty infiltration as similar to the controls.

Conclusion: The methanolic extract of D. cinerea stem bark and the phytoconstituent 6-heptadecylcyclohex-3-ene-1 carboxylic acid showed significant protection from CCl4 induced liver damage.
