RESUMO
Alcoholic extract and various fractions of Achyranthes aspera leaves, traditionally used in Pakistan for treatment of infectious diseases was screened for in vitro antibacterial and antifungal activity. The chloroform and butanol fractions were found to be the most active among the fractions, showing considerable antibacterial activity against Shigella flexneri and Escherichia coli. The highest activity was found in the ethylacetate fraction [17 mm zone of inhibition] against gram-negative [Salmonella typhi] bacteria, with MIC value as 0.29 mg/mL. In antifungal screening, moderate activity was shown by the chloroform fraction [50 % inhibition] against Microsporum cams, with MIC value as 0.25mg/mL. Considerable level of antifungal activity was depicted by crude extract, hexane and butanol fractions against Aspergillus flavus and Microsporum canis. The ability of various extracts of Achyranthes aspera to inhibit different strains of fungi and bacteria indicates its potential use for the treatment of microbial infections

In present study, the anti-inflammatory potential of three medicinal plants, Xanthium strumarium, Achyranthes aspera and Duchesnea indica were evaluated, using both in vitro and in vivo assays. Carrageenan induced hind paw edema model was used to carry out the in vivo anti-inflammatory activity, while for in vitro screening lipoxygenase inhibition assay was used. Crude extract of all the selected plants depicted significant [p = 0.001] anti-inflammatory activity, at late phase of inflammation. Achyranthes aspera also showed considerable anti-inflammatory activity [47%] at relatively lower concentration [200 mg/ml], at the initial phase of inflammation. Similarly the ethyl acetate fraction of all the selected plants showed significant lipoxygenase inhibition activity when compared with the standard drug [Baicalein]. The results obtained from both in vitro and in vivo anti-inflammatory activity suggest that the ethyl acetate fraction of the crude extract of all the selected plants can be used for the isolation of new lead compounds with better anti-inflammatory activity
RESUMO
The current study was undertaken to estimate the concentration of micronutrients [Zn, Fe, Pb, Cu, Ni, Cd, Cr, Co, Sb and Mn], macronutrients [Na, Ca and K] and essential life nutrients [proteins, fats, carbohydrates and ascorbic acid] along with ash, fiber and moisture contents. Atomic absorption spectrophotometer was employed for the analysis of micronutrients while flame photometry for macronutrients. For proximate analysis [proteins, fats, carbohydrates, ash, fibers and moisture], Association of Official Analytical Chemists methods [AOAC] were used and titration method for ascorbic acid determination. It is evident from the results that the crude extract and its fractions accumulate significant concentrations of both micro and macro nutrients. The significant quantities of essential life nutrients like proteins, fats, carbohydrates and ascorbic acid along with ash, fiber and moisture contents were also found in extracts. It is concluded that the extracts of rhizomes accumulated significant quantities of life indispensible nutrients and validated the ethnobotanical uses of the plant as tonic and energizer
