Abstract

In the present study the antifungal activities of hot and cold alcoholic extracts of fresh water green macro-algae Spirogyra sp. was investigated against plant fungi (Fusarium oxysporum). Hot and cold alcoholic extract showed antifungal activity against the specie of fungi in different concentrations (25,50,75mg/ml)as percentage inhibition (87.11, 90.33,100) and (67.18,81.21,89.43) respectively. Also the results showed the ability of algal extract to protect tomato seed and promoted seed growth when soaked in extracts for less than 48 hours. Primary detection of active compounds showed that macro-algae (Spirogyra sp.) containing Flavonoids, Alkaloids, Phenols and Saponins. In this study the bioactive compound have been evaluated by using GC-Mass spectrophotometer.
