Since the natural antioxidants do not cause any undesirable side effects, they have more preferences in comparison to those synthetic. Today, the scientists‘ attention is more and more drawn to P-active substances of phenolic origin (bioflavonoids): catechinins, anthocyanins, leucoanthocyanins, flavone glycosides, chlorogenous acid and others. There are many evidences advocating this fact. The objectives of this work are to choose the optimum parameters of maximal
bioflavonoid extraction from 10 samples of medicinal herb with subsequent practical use in production of natural food additives.
