Quantification Of Total Phenolics And Flavonoids And Evaluation Of In Vitro Antioxidant Properties Of Methanolic Leaf Extract Of Tarenna Asiatica – An Endemic Medicinal Plant Species Of Maruthamali Hills, Western Ghats, Tami Nadu.

Transcript

The present study was aimed at to determine the preliminary phytochemical screening, quantification of total phenolics and flavonoids and to evaluate the antioxidant activities of an endemic medicinal plant species, Tarenna asiatica. The antioxidant activity of methanolic leaf extract of this species was assessed by DPPH•, ferrous ion chelating, reducing power and ABTS•+ radical scavenging activities. The total phenolics and flavonoids content of the extract were found to be 16.95μg of GAE/100mg extract and 3.72μg of QE/100mg extract respectively. The present study revealed that the methanolic leaf extract of this speices showed potent in vitro antioxidant activities and so it may be useful for their nutritional and medicinal properties.
