Sažetak
Chamomile tea is a remedy with a very long history of use and one of the most popular remedies in traditional medicine throughout the world. Dried leaves and tea infusions of German and Roman chamomile show some differences in phytonutrient content. Phytonutrients found in dried German chamomile include caffeic and ferulic acid [1], while catechin, gallocatechin and epicatechin were found in the tea infusion [2]. In case of Roman Chamomile, lignans were determined in the tea infusion [3]. Other than to determine phenol profile of these two plants, our aim was also to evaluate the antioxidant potential of selected compounds in silico using density-functional theory. The main focus was on thermodynamics and studied mechanisms were hydrogen atom transfer and sequential proton loss electron transfer. Based on obtained results it is clear that the studied compounds possess significant free radical scavenging potency and can efficiently deactivate various free radicals. Second hydrogen atom transfer and second sequential proton loss electron transfer processes are determined to be less energy demanding than the first ones.
