Antioxidant activity of some common plants

Öz:

Çok sık kullanılan bazı tıbbi bitkilerin metanolik ham özütleri ile serbest radikal süpürme aktivitelerii standart antioksidant olarak askorbik asit kullanılarak incelenmiştir. Serbest radikal süpürücü aktivite için 1,1-difenil-2-pikril-hidrazil serbest radikali kullanılmıştır. Antioksidant aktivitesi en yüksek, yeşil çayda (Camellia sinensis Linn.) gözlenirken, siyah çay (Camellia sinensis Linn.), Eugenia caryophyllus (Spreng.) Bullock ve Harrison, Piper cubeba Linn., Zingiber officinale Roscoe ve Piper nigrum Linn, onu azalarak takip etmişlerdir. DPPH yöntemi ile, Trigonella foenum graecum Linn. ve Elettaria cardamomum (Linn.) Maton, zayıf serbest radikal süpürücü aktivite göstermiştir. Bütün metanolik özütler önemli ölçüde antioksidant aktivite göstermiştir. Metanolik özütün IC50 değeri 6.7 ± 0.1 ile 681.5 ± 8.4 μg/ml arasında değişirken, askorbik asitin değeri 8.9 ± 0.1 μg/ml bulunmuştur. Bu çalışma ile incelenen bitkilerin verimli antioksidant aktivite özelliği gösterdikleri açığa çıkarılmıştır.

Öz:

The methanolic crude extracts of some commonly used medicinal plants were screened for their free radical scavenging properties using ascorbic acid as standard antioxidant. Free radical scavenging activity was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical. The overall antioxidant activity of green tea (Camellia sinensis Linn.) was the strongest, followed in descending order by black tea (Camellia sinensis Linn.), Eugenia caryophyllus (Spreng.) Bullock and Harrison, Piper cubeba Linn., Zingiber officinale Roscoe and Piper nigrum Linn. Trigonella foenum graecum Linn. and Elettaria cardamomum (Linn.) Maton showed weak free radical scavenging activity with the DPPH method. All the methanolic extracts exhibited antioxidant activity significantly. The IC50 of the methanolic extracts ranged between 6.7 ± 0.1 and 681.5 ± 8.4 μg/ml and that of ascorbic acid was 8.9 ± 0.1 μg/ml. The study reveals that the consumption of these spices would exert several beneficial effects by virtue of their antioxidant activity.
