Abstract: Plants are the best gifts that the Mother Nature has given us. They not only give us food but also nurture us while we fall sick. Since past decades, plants are proved to be the repertoires of myriads of pharmacologically important molecules that have been isolated, characterized, identified and applied for the treatment of various number of diseases. The scientific community has successfully employed the plants as biomedicines. This research work is the outcome of interest towards understanding the alchemical units in medicinal plant and its associated fungi that have the ability to combat the disease cancer. The study was carried to evaluate the crude extracts’ antioxidant activities, estimation of total phenolics and free radical scavenging activity. Total antioxidant capacity of the extracts of Cassia fistula was evaluated by the phosphomolybdenum method and was expressed as μg of ascorbic acid equivalents (AAE) per ml of plant extract. Total antioxidant capacity of the test samples was calculated using the standard curve of ascorbic acid. Methanol and aqueous extracts of Cassia fistula were found to possess the highest total antioxidant capacity compared to chloroform extracts.
