Screening of antioxidant and radical scavenging activities of some Omani medicinal plants

Abstract EN

N-Butanol extracts of nine medicinal plants, Cressa cretica, Sisyphus spinachrist, Acacia tortillas, Tephrosia haussknechti, Aristolochiae bracteolate, Catullus colocynthis, Teucrium mascatense, Rhazya stricta and Nerium oleander, found in Oman were screened for their antioxidant activity using phosphomolybdenum complex assays and their radical scavenging activity using DPPH assays.

Osmium basilica, a plant with well documented antioxidant activity, was used as a reference.

A.

tortilis and T.

haussknechti extracts possessed very high antioxidant activity (AOA) and high radical scavenging activity (RSA).
