In-Vitro Antioxidant potentials in leaves of Coleus aromaticus Benth and rhizomes of Zingiber zerumbet (L.) SM.

ABSTRACT

Antioxidant activity of aqueous extracts of two common plants, Parnayavani- leaves of Coleus aromaticus Benth and Sthulagranthi- rhizomes of Zingiber zerumbet (L.) Sm. was investigated by adopting various in vitro models such as DPPH assay and Nitric oxide radical scavenging assay. The results of the study show that both plants possesses significant free radical scavenging properties and a clear correlation exists between the antioxidant activity.
