Determination of antioxidant activities of different extracts of in vitro plantlets of Murraya koenigii L. Spreng

Abstract

Murraya koenigii (L) Spreng, locally known as “curry patta” or “mithaneem” (curry leaf tree) belonging to family Rutaceae, is commonly used as raw material for traditional medicinal formulation in India. Its aromatic leaves contain essential oil and is used as condiments. The fresh leaves of Murraya koenigii have been reported to possess anti-microbial, mosquitocidal, topo-isomerase inhibition and antioxidant properties. The present paper aims to undertake a comparative study of antioxidant potential of extracts of in vitro plant parts. Four different plant materials were tested for the determination of antioxidant activity. These plant materials include ADVS, ADVR, AXLS and AXLR. The stable DPPH was used for in vitro determination of free radical scavenging activity of the extracts. The strongest DPPH radical scavenging activity was exhibited by extract of AXLS and lowest activity was found in the ADVR. Present investigation reports first on comparative in vitro analysis of antioxidant potential of extracts ADVS, ADVR, AXLS and AXLR of M. koenigii.
