Indian Journal of Experimental Biology. 2013 Oct; 51(10): 828-832.http://imsear.searo.who.int/handle/123456789/149388Methanolic and ethyl acetate extract of A. galanga showed significant central nervous system (CNS) stimulant activity in mice using actophotometer and rotarod test. CNS stimulation at a dose of 500 mg/kg was comparable with standard drugs caffeine and amphetamine derivative modalart. The extracts did not shown any depressant effect in forced swim or tail suspension tests. It can be concluded that A. galanga rhizome may have stimulant activity in mice and the active constituents responsible for this effect is present both in crude methanolic extract as well as in ethyl acetate fraction of methanolic extract of this plant species.enAlpinia galangaMiceRhizomeStimulantAlpinia --chemistryAnimalsCentral Nervous System --drug effectsCentral Nervous System Stimulants --pharmacologyLocomotion --drug effectsMaleMicePilot ProjectsPlant Extracts --pharmacologyPsychomotor Performance --drug effectsRhizome --chemistryArticle
