Abstract
The present study evaluated the free radical scavenging and anticholinesterase activity of the methanolic extracts of Acorus calamus (ACME) and Nardostachys jatamansi (NJME) rhizomes in vitro. In addition, total phenolics (TP) were also estimated. NJME contained significantly higher (p =0.05) phenolics (37 μg GAE/mg) than ACME (23μg GAE/mg). Consequently, NJME exhibited significantly higher (p =0.05) radical scavenging activity than ACME and BHT, a synthetic antioxidant. Further, the IC50 values were 704, 237 & 335 μg/ml for ACME, NJME and BHT respectively. In case of anticholinesterase activity also NJME exhibited significantly higher (p =0.05) activity with lower IC50 value than ACME. However, the anticholinesterase activity of both ACME and NJME were significantly lower (p =0.05) than neostigmine, a standard drug wherein, neostigmine exhibited significantly lower (p =0.05) IC50 value than ACME and NJME. Furthermore, a significant correlation between the total phenolic content, antioxidant and anticholinesterase activities of both the extracts indicating that total phenolics might be responsible for the observed antioxidant and anticholinesterase activities.This is the first report in this direction.
