The effect of the Satureja montana ethanol extract on the morphological changes of erythrocytes
Marija Marin | Snežana Branković
The present study investigated the antioxidant activity of ethanol extracts of the leaves of Satureja montana and their influence on the membrane stability of erythrocytes ex vivo. The ethanol extracts showed a very potent antioxidant activity of EC50 = 0.055mg/ml. Rat blood samples were treated with 96% ethanol extracts in different concentrations of 100 µg/ml, 200 µg/ml, and 300 µg/ml, and morphological analyses were carried out. The results showed significant differences in the shape of the erythrocytes incubated with higher extract concentrations. Considerable morphological changes were observed at a concentration of 200 µg/ml which was characterised by the highest percentage of stomatocytes, while the highest percentage of echinocyte formation was observed at a concentration of 300 µg/ml. The results of this investigation indicated that the ethanol extracts of S. montana exhibited a possible protective effect on the membrane stability of erythrocytes.
