Abstract:
Hepatotoxicity is a major complication of acetaminophen (APAP), widely usedanalgesic and antipyretic drug. Asparagus racemosus (AR) is an Ayurvedic rasayana,
which is used for treatment of different diseases by their active compounds. This studyincorporates the protective effect of ethanol fraction of AR roots on acetaminopheninduced hepatic toxicity and hepatic damage in rats. This fraction displayed significant
DPPH free radical scavenging activity against standard ascorbic acid and contains
flavonoids and phenolic compounds in high amount. Ethanol fraction of AR was fedto acetaminophen (500mg/kg body weight) induced hepatotoxicity in rats at different
doses. Maximum hepatoprotective effect was shown by AR at the dose of 500mg/kgbody weight. The marker enzymes of liver toxicity like ALP, AST, ALT, GOT andGPT levels were increased significantly in case of acetaminophen treated group where
these enzyme levels significantly resettled to the normal after AR treatment. Also the
haematological parameters like haemoglobin and RBC level were significantlyincreased after treatment of ethanol fraction of AR at 500mg/kg. Acetaminopheninjection resulted decrease in liver GSH content which was restored after treatment of
AR. Histological pattern of rat liver subjected to acetaminophen hepatotoxicityrevealed degenerative changes of liver tissues where after treatment of AR at highdose improvement and rearrangement of liver cells was prominent. These results
indicate that the compounds present in the ethanol fraction of AR possesses
hepatoprotective activity against acetaminophen induced hepatotoxicity in rats.
