%0 Journal Article %T Extraction of Ashwagandha by conventional extraction methods and evaluation of its anti-stress activity %A Jain H %A Parial S %A Jarald E %A Daud Anwar %J International Journal of Green Pharmacy %D 2010 %I Medknow Publications %X The present study was conducted to compare the yield and the antistress activity of Ashwagandha (Withania somnifera) extracts, using two extraction methods: hot continuous percolation and maceration. Various parameters like temperature, extraction time (10 hours) solvents (water, alcohol, hydroalcohol) and drug-solvent ratios (1:6, 1:8, 1:10) were fixed. The highest yield was found to be 16.96% w/w by maceration process using water (1:8). The activity of different extracts was done by Plus-Maze model using alprazolam as the standard drug. Significant result was found in water extract and hydroalcoholic (1:8) extract prepared by maceration method and also in hydro-alcoholic extract (1:8) prepared by soxhlet process. %K Alprazolam %K anti-stress activity %K elevated plus maze %K extraction %K withania somnifera %U http://www.greenpharmacy.info/article.asp?issn=0973-8258;year=2010;volume=4;issue=3;spage=183;epage=185;aulast=Jain
