Abstract: Tecoma stans is a flowering perennial plant characterized by the presence of yellow colored trumpet-shaped flowers. The various parts of the plant possess several medicinal properties due to the presence of diversified group of biologically/ pharmacologically active phytochemicals and are used therapeutically for the treatment of various diseases such as diabetes, cancer, yeast infections etc. The plant is reported to hold the medicinal value as a powerful diuretic, vermifuge, cardiotonic, anti-spasmodic agent apart from its use as an ornamental, fuel, timber, shade/shelter, and barrier. Based on the consideration of these facts, we engaged to study in-vitro antioxidant activity, determination of total phenolic and flavonoid content of different extracts of T.stans. The antioxidant activity was observed to be high in stem methanolic extract. The leaf methanolic extract tends to contain more phenolic content (60.24 mg GAE/ gr. Ext.). The total flavonoid content was observed to be high in leaf methanolic extract (324.80 mg QE/gr. Ext.) and leaf aq. methanolic extract (127.18 mg CE/gr.Ext.) in terms of quercetin and catechin equivalents respectively.
