Abstract


Background: Global burden of disease statistics indicate that 4 of 10 most important causes of disease worldwide are psychiatric in origin. Anxiety affects 1/8th of total population of the world and is a very important area of research interest in psychopharmacology. Medicinal plants and plant products are the oldest tried health-care products. Their importance is growing not only in developing countries but in many developed countries. Curcuma amada Roxb. (CA) commonly known as Mango Ginger is a rhizomatous aromatic herb which is used in this country for culinary purposes and also to treat various diseases. The rhizomes of Curcuma amada was screened for anxiolytic activity and locomotor behavior in Wistar albino rats.

Methods: Wistar albino rats were divided into three groups as control (Distilled water with 0.1% CMC), standard (Diazepam - 1mg/kg) and test - Ethanolic Extract of Curcuma amada Rhizome (EECAR-250 mg/kg). They were administered drugs orally for a period of 10 days, and screened for anxiolytic activity using Light dark arena model and Actophotometer for assessing the locomotor behavior on the 10th day. The number of crossings and time spent in light arena for anxiolytic activity, and the number of movements in Actophotometer was noted. Data was analyzed by one way ANOVA followed by Tukey Kramer multiple comparison test using GraphPad InStat software.

Results: Curcuma amada (250mg/kg) showed increased time spent in light arena and decreased locomotor behavior which was statistically significant.

Conclusions: Curcuma amada possesses significant anxiolytic with CNS depressant activity.
