Medicines from yarrow have medicinal properties and render styptic, spazmolitic, wound healing, bile-expelling action. They also show antioxidant, antibacterial and antifungal activity. Medicinal properties of these medicines are caused by existence in them of phenolic compounds (flavonoids, tannins, vitamin C). The purpose of this work is a research of antioxidant properties of ethylacetate extracts preparing from different types of yarrows growing in a South-East part of the Republic of Armenia. Experimental data of antioxidant activities (AOA) and effective content of antioxidants (AO) in the ethylacetate extracts of three tipes of yarrows are given in this study on the example of model reaction of cumene oxidation. It is shown that the studied yarrows are distributed in a row by the effective content of antioxidants: Achilleaaurea>Achillea nobilis>Achillea ...
