Combinatorial Interactions of Essential Oils Enriched with Individual Polyphenols, Polyphenol Mixes, and Plant Extracts: Multi-Antioxidant Systems.

ABSTRACT: With the aim to develop essential oil (EO) multi-antioxidant systems, combinatorial interactions of selected phenol and terpene-rich EOs (from Pimento Berry, Ceylon Cinnamon, Clove, Sage, White thyme; Oregano) enriched with individual polyphenols, crude plant extracts, and mixtures of their major polyphenols were investigated using single electron transfer (SET)-based DPPH and hydrogen atom transfer (HAT)-based ORAC assays. Polyphenols that enriched Eos the most favorably were rosmarinic acid (IC₅₀ of 0.0891-0.1448 mg enriched EO/mg DPPH; 5772-17,879 µmol TE/g enriched EO) and quercetin (IC₅₀ of 0.0682-0.1060 mg enriched EO/mg DPPH; Trolox Equivalents (TE) of 9776-14,567µmol /g enriched EO), whereas p-coumaric acid (IC₅₀ of 0.1865-1.1424 mg enriched
