This work describes antioxidant effect of 15 kinds of herbs. Three different antioxidant assays were used, Trolox equivalent antiradical activity (TEAC), test based on deoxyribose oxidation and DPPH method. The TEAC values ranged from 0.38mM to 0.77 mM. Deoxyribose assay showed antioxidant activity of selected extracts expressed as the inhibition of formation of oxidative products of deoxyribose from 2.68 to 50.05 %.<span style="mso-spacerun: yes;">&nbsp; </span>The DPPH method values ranged from 6.47 to 73.80 %. </span></span></span></p><p class="MsoNormal" style="margin: 0cm 0cm 0pt; line-height: 150%; text-align: justify;"><span style="font-size: small;"><span style="font-family: Times New Roman;"><span style="mso-ansi-language: EN-US;" lang="EN-US">Extracts of <em>Prunus spinosa</em> L., <em>Euphrasia rostkoviana Hayne</em> were the best antioxidants confirmed by all methods. <em>Scrophularia nodosa</em> L. extract showed the weak antioxidant effect<span style="mso-spacerun: yes;">&nbsp; </span>determined by all selected methods. Phenolic content was in relation to the antioxidant effect of herbs, </span>very high significancy between DPPH and polyphenols content was found. To improve selected properties of apple juice (taste, smell, functional properties) by addition of medicinal herbs was achieved in this work. Antioxidant effect<span style="mso-spacerun: yes;">&nbsp; </span>of <span style="mso-spacerun: yes;">&nbsp;</span>apple juice variants with herbs additions determined by DPPH method was high and ranged from 73 to 78.49 %. Herbal extracts can be utilised in selected combinations to improve sensory and functional properties of some kinds of beverages.</span></span></p><p class="MsoNormal" style="margin: 0cm 0cm 0pt; line-height: 150%; text-align: justify;">&nbsp;</p><p class="MsoNormal" style="margin: 0cm 0cm 0pt; line-height: 150%; text-align: justify;"><span style="font-size: small;"><span style="font-family: Times New Roman;"><span style="line-height: normal; font-size: 12px; font-family: Verdana, Arial, Helvetica, sans-serif;"><strong>doi:10.5219/75</strong></span></span></span></p>
