Among the plants studied, Melissa officinalis L. showed the highest values in total phenolic content (0.985 ± 0.001 mg caffeic acid/mL) and antioxidant activity (6.61 ± 0.04 mol Trolox/mL) independently of the extraction process. Toxicity evaluation of the infusions prepared in concentrations contained in commercial portions showed that inhibition values of Origanum vulgare L. and Origanum dictamnus L. were greater than 20% thus further research is necessary. Although toxicity of plant extracts examined is not correlated to their total phenolic content and antioxidant activity, it was linked to the interaction of water soluble and volatile organic compounds. Interaction of water soluble and volatile organic compounds was evaluated through the estimation of synergism ratios (SR), where Origanum vulgare L., presented the maximum synergism (SR = 4.2) in toxicity. 9 pp. LOMv1.0 creator LOMv1.0 publisher LOMv1.0 Project Final Beneficiary LOMv1.0 Project Executing Organisation 2014 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text Toxicity Lamiaceae Synergism Total phenolic content Antioxidant activity Health quality improvement Phenolic compounds irakleitos2.aua.gr/sites/default/files/ΔΗΜΟΣΙΕΥΣΗ_0.pdf 431438 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/2788/2/2788_Document-007.pdf URI http://hdl.handle.net/10795/2788 LOMv1.0creator 2016-04-20T12:55:50Z LOMv1.0validator 2016-04-20T12:55:50Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
