Free radicals, usually ROS and RNShave the potential to harm macromolecules including DNA, proteins, and lipids at high quantities. Plants may contain a wide variety of free radicalscavenging molecules, such as phenolic compounds. Which are rich in antioxidantactivity. Clerodendrum indicum L. is frequently used in traditional medicine in India for curing various diseases. Considering its benefit this study aims at investigating its phytochemical & antioxidant activity. The plant material was collected & subjected to extraction. Further qualitative & quantitative test along with antioxidants assays were also performed. Results revealed that plant contain flavonoid, diterpene, phenol, protein and saponin. Total phenol & flavonoid content was found to be 1.580 mg/100mg & 0.856 mg/100mg.The IC 50 value for ascorbic acid was observed to be 27.82 while for extract it is noticed to be 150.53 indicating that the plant extract possess some antioxidant potential. Hence further studies are needed to found the actual mechanism involved in the antioxidant property and other pharmacological activities of C. indicum.
