VAMIKAAbstract Antioxidants play a vital role in the prevention of various diseases. In this background, methanolic flower extract of Tabernae montana heyneana was evaluated for the antioxidant properties. Significant metal ion (ferric, cupric and ceric) reducing power was observed in the methanolic extracts. Appreciable ferrous ion chelation (74.55% ± 4.62; IC50 = 589 μg/mL) and poor hydroxyl ion scavenging (28.53% ± 6.53; IC50 = 639 μg/mL) properties were recorded. Similarly, one way ANOVA results of ABTS and DPPH assays proved that there is no significant difference at 5% (p > 0.05) between the extracts and standard molecules, and the results were also supported by substantially recorded IC50 values. Hence, the flower extract of T. heyneana may be considered as a promising herbal medicine to cure a wide spectrum of diseases.
