文摘
- •
Reaction between DPPH and trans-aconitic acid (TAA) is explained by a joint experimental/theoretical study.
- •
Hydrogen atom abstraction by DPPH
should be located on methylene bridge in TAA.- •
Trans-aconitic acid (TAA) alone is an antioxidant with low efficiency.
- •
In combination with vitamin C, trolox, gallic, caffeic acids, TAA provides an antioxidant synergistic or additive effect depending on TAA concentration.
