Chive (Allium schoenoprasum L.) is a small bulbous perennial which is used as a spice plant and
as a culinary herb. This plant contains compounds with potent antioxidant activity and has beneficial
effect on human health. Chive can be easily grown without special care. Accordingly, it would
be the best that people grow spice and healthy plants on their own balconies and terraces to have
fresh raw plant like chive every day. The objective of this study was to determine the impact of urban
environmental factors on the quality of chives planted at 5 different locations in Belgrade. The parameters of quality were phenolics profile and heavy metals content, while exposure to stress
was determined by measuring the activity of antioxidant enzymes, peroxidases (POX) and superoxide
dismutases (SOD) in fresh plants. The phenolics profile of plant aerial parts was characterized
by LC-MS/MS. Twelve phenolic compounds were quantified, among which kaempferol 3-O-glucoside
and quercetin 3-O-glucoside were dominant. Positive correlation between POX/SOD activity
and concentrations of the forementioned compounds was observed. The concentrations of Cd,
Cr, Cu, Pb and Zn in the leaves of investigated chives were measured using ICP-OES technique.
The levels of Cd in edible parts of chive at all investigated locations were higher than permissible
limit. Mean Cr concentration in leaves of chive was high only in central urban zone. The process of
urbanization has been expanded with the negative consequences on plants, which can be seen
from increased POX activity and high levels of heavy metals in leaves of chives.
