Abstract

n-Butanol extracts of nine medicinal plants, Cressa cretica, Ziziphus spina-christ, Acacia tortilis, Tephrosia haussknechti, Aristolochiae bracteolata, Citrullus 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. Ocimumi basilicum, 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).
