TAILIEUCHUNG - Comparative antioxidant activity of some edible plants

Terminalia chebula, Salvia officinalis L., Calamintha incana, Thymus vulgaris L., Matricaria chamomilla, and Nigella sativa are commonly used spices. In the present study the methanolic extracts of these spices were evaluated for their antioxidant activity by the 1,1-diphenyl-2-picryl-hydrazyl (DPPH) free radical scavenging method. | Turk J Biol 32 (2008) 193-196 © TÜBİTAK Comparative Antioxidant Activity of Some Edible Plants Zaha A.

In the present study the methanolic extracts of these spices were evaluated for their antioxidant activity by the 1,1-diphenyl-2-picryl-hydrazyl (DPPH) free radical scavenging method. All the methanolic extracts showed significant antioxidant activity. The IC50 of the methanolic extracts ranged between ± and ± μg/ml, and that of ascorbic acid was ± μg/ml. The study revealed that the consumption of these spices could exert several beneficial effects by virtue of their antioxidant activity. Key Words: Terminalia chebula, Salvia officinalis L., Calamintha incana, Thymus vulgaris L., Matricaria chamomilla, Nigella sativa, antioxidant activity, DPPH, ascorbic acid, methanolic extract Bazı Yenilebilen Bitkilerin Antioksidant Aktivitelerinin Karşılaştırılması Özet: Terminalia chebula, Salvia officinalis L., Calamintha incana, Thymus vulgaris L., Matricaria chamomilla ve Nigella sativa baharat olarak sık kullanılan bitkilerdir. Bu çalışmamızda bu baharatların metanolik özütleri 1,1-difenil-2-pikrill-hidrazil serbest radikal süpürücü etkisi yöntemi ile antioksidant etkileri incelenmiştir. Metanolik özütlerin tamamı önemli ölçüde antioksidant aktivite göstermişlerdir. Metanolik özütlerin IC50 değerleri 3,8 ± 0,1 ile 168,8 ± 2,1 μg/ml arasında değişirken askorbik asidin değeri ise 8,6 ± 0,1 μg/ml olarak ölçülmüştür. Bu baharatların kullanımı antioksidant aktiviteleri nedeniyle insanlara bir çok faydaları olabilir.
