Several commercial varieties of tinctures were analyzed for determining their antioxidant potential, since most knowledge relating to therapeutic properties of medicines are obtained from folk phytomedicine. Antioxidant potential was determined by the scavenging activity of 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3- ethylbenzothiazoline-6-sulphonic acid) (ABTS) free radicals, reducing power, and chelating activity. The best results against scavenging of free radicals were obtained with tincture from Vaccinium vitis-idaea,followed by Capsicum annuum and Melissa officinalis. There were obvious significant differences between the free radicals’ scavenging activities. Results were correlated with values obtained for reducing power and chelating ability. This finding was also confirmed by the low values of the EC50. Also, the results were positively high when correlated with total phenolic and flavonoidic contents from the tinctures. The results given herein are the scientific proof that confirms the empirical medical knowledge on how to use the three tinctures in oxidative dysfunctions.
