Cassia fistula Linn. (Leguminosae) is a tree distributed throughout South India. It is known as Golden shower tree. Only a few works were done previously on Cassia fistula pod. Present study is concentrated on antimicrobial, anthelmintic and phytochemical aspects of the Cassia fistula pod. For this the fruit extracts were used. The methanolic extract of Cassia fistula seed was investigated for potential antimicrobial activity against medicinally important bacteria. The water extract from the pods of Cassia fistula Linn. were investigated for their anthelmintic activity. Four concentrations (1%, 2%, 5%, crude, albendazole ) of extract were studied, which involve determination of time of paralysis and death of worms. As the plant possess several secondary metabolic compounds, it provides protection against insect attack and invasion of pathogen. These properties can be investigated by a thorough analysis. So that the economic potentialities can be exploited commercially.
