(75, 150, 300 mg\/kg, p.o.).\u00a0 The exts. exhibited significant (P < 0.01) anti-inflammatory activity, supporting its use as traditional medicine.\u00a0 The study established anti-inflammatory activity of the leaves of Acorus calamus. \n\n2) The present study evaluated the free radical scavenging and anticholinesterase activity of the methanolic exts. of Acorus calamus (ACME) and Nardostachys jatamansi (NJME) rhizomes in vitro.\u00a0 In addn., total phenolics (TP) were also estd.\u00a0 NJME contained significantly higher (p = 0.05) phenolics (37 mg GAE\/mg) than ACME (23mg GAE\/mg).\u00a0 Consequently, NJME exhibited significantly higher (p = 0.05) radical scavenging activity than ACME and BHT, a synthetic antioxidant.\u00a0 Further, the IC50 values were 704, 237 & 335 mg\/mL for ACME, NJME and BHT resp.\u00a0 In case of anticholinesterase activity also NJME exhibited significantly higher (p = 0.05) activity with lower IC50 value than ACME.\u00a0 However, the anticholinesterase activity of both ACME and NJME were significantly lower (p = 0.05) than neostigmine, a std. drug wherein, neostigmine exhibited significantly lower (p = 0.05) IC50 value than ACME and NJME.\u00a0 Furthermore, a significant correlation between the total phenolic content, antioxidant and anticholinesterase activities of both the exts. indicating that total phenolics might be responsible for the obsd. antioxidant and anticholinesterase activities.\u00a0 This is the first report in this direction. \n\n3) A pectic polysaccharide was isolated from the rhizomes of Acorus calamus L. The main component of its carbohydrate chain was represented by residues of D-galacturonic acid (> 85%).\u00a0 In addn., this polysaccharide contained residues of galactose, arabinose, xylose and rhamnose (< 10%).\u00a0 Structural anal. of pectic polysaccharide from A . calamus L. with NMR spectroscopy indicated that it contains the regions of a linear 1,4-alpha-D-galactopyranosyluronan, which represents a major component of the macromol.\u00a0 A considerable amt. of galacturonic acid residues was not methoxylated.\u00a0 We demonstrate here that the pectic polysaccharide from A. calamus L. in low concns. was able to stimulate in vitro IL-12 and nitric oxide prodn. by murine macrophages.\u00a0 It also induced TNF-alpha secretion by human peripheral blood mononuclear cells, reduced arginase activity but did not affect IL-10 secretion by murine macrophages or human peripheral blood mononuclear cells.\u00a0 The IL-12 and NO-stimulating effects on murine macrophages were similar to that of LPS.\u00a0 In addn., the polysaccharide promoted in vivo Th1 immune response in mice which were immunized with sheep red blood cells (DTH and quantity of plaque-forming cells) and down regulated serum level of IgG1 and Ig[n.1045] during Th2-depend immune response induced by ovalbumin.\u00a0 The PS increased Th1-induced edema and suppressed Th2-induced paw swelling in adoptive systems.\u00a0 Our results suggest that the pectic polysaccharide from A. calamus L. represents a promising immunomodulating agent that stimulates M1-polarized macrophages and promotes Th1-oriented adaptive immune response.\u00a0 We propose that this polysaccharide could be potentially applied for treatment of infectious, oncol. diseases or for Ig-E-mediated disorders.
