Abstract
Indian Laburnum (Cassia fistula L.) bark, stem, leaf and ischolar_main under different age classes namely Class A (2-3 years), Class B (5-10 years) and Class C (10-15 years) were analyzed for their total phenolic content (TPC), total tannin content (TTC) and antioxidant activity (AA). Both total phenolic content (TPC) and total tannin content (TTC) were determined using Folin-Ciocalteau assays and antioxidant activity (AA) was carried out by Free Radical 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. From the study, higher TPC, TTC and AA were observed in Cassia fistula bark extracts compare to otherportion extracts (stem, leaf and ischolar_main). Bark extracts from three different age classes, showed total means of 16.67 % TPC and 3.12% TTC. In addition, bark extracts from three different age classes also showed high antioxidant activity (AA) with mean IC 50 values of 0.04g/ml.
