In-Vitro antioxidant potential and phytochemical screening of Tectona grandis Linn. leaves


Tectona grandis Linn. belongs to family Verbenaceae commonly known as Teak and is found in India and South-East Asian countries. It is known for its medicinal value traditionally to cure diseases such as diabetes, anti-inflammatory and infectious diseases and has its timber value too. In-vitro antioxidant activity and phytochemical investigation was carried out for successive solvent extracts such as petroleum ether, chloroform, ethyl acetate, methanol and water. The reducing power assay and nitric oxide inhibition assay and DPPH assay demonstrate that the methanolic extract have higher antioxidant activity than others when compared with ascorbic acid as standard. The Phytochemical investigation of methanolic extract also reveals that it has tannins, flavonoids and phenolic contents present in it which are responsible for its antioxidant activity. Thus methanolic extract of the plant will be suggested for futher investigation to determine in-vivo antioxidant activity for diseases in which oxidative stress play a major role.
