Comparative study on Allium schoenoprasum cultivated plant and Allium schoenoprasum tissue culture organs antioxidant status.

This study was designed to examine Allium schoenoprasum tissue culture organs antioxidant and scavenging activity and to make a comparison between Allium schoenoprasum cultivated plant and Allium schoenoprasum tissue culture organs antioxidant activity. This study reports the results on the root, stalk and leaf antioxidant enzyme activities (superoxide dismutase, catalase, guaiacol peroxidase and glutathione peroxidase), reduced glutathione quantity, flavonoids and soluble protein contents and quantities of malonyldialdehyde and ·OH radical. In Allium schoenoprasum tissue culture organs the total antioxidant capacity was determined by the FRAP method and scavenger activity by the DPPH method. The present results indicated that the crude extract of Allium schoenoprasum tissue culture exhibited antioxidant and scavenging abilities in all investigated plant parts, especially in the roots. According to our results, the tissue culture plants exhibited the highest activities in the roots in contrast to the cultivated plants where highest activities were observed in the leaves.
