Total phenolic content and peroxidase activity in Salanova lettuce
Апстракт
Lettuce (Lactuca sativa L.) belongs to a group of leafy vegetables commonly used as a salad
in human nutrition. As minimally processed food product, it is an important source of vitamins,
minerals and various antioxidative compounds. In our greenhouse experiment, two Salanova let tuce cultivars (‘Aquino‘ RZ- green and ‘Gaugin‘ RZ- red multi-leaf butterhead) were grown in the
fertile soil during three successive seasons (autumn, winter and spring). The aim of the study was
to examine the effect of different microbiological fertilizers (EM Aktiv, Vital Tricho and combination
of EM Aktiv and Vital Tricho), cultivars and growing seasons on the total phenolic content and
peroxidase activity. Our results showed that in all seasons red cultivar ‘Gaugin‘ had higher total
phenolic content compared to green cultivar ‘Aquino‘. Their highest level was measured in au tumn with fertilizer Vital Tricho (549.14 µg GAE g-1 FW). The elevated phenolic status of red versus
green cultivar w...as further strengthened by its higher level of peroxidase with the highest activity
measured in spring with combination of fertilizers EM Aktiv and Vital Tricho (0.43 U mg-1 prot). The
higher peroxidase activity and content of UV-absorbing phenolics, as plant-borne substrates of
these enzymes, in the red cultivars indicate that the red leaves are better equipped to combat
oxidative stress. Consequently, red cultivar ‘Gaugin‘, with increased synthesis of health-promoting
antioxidants, could be considered as functional food in human diet.
