Abstract:
This paper demonstrates for the first time that plant metabolites of the phenylamide type, conjugates of putrescine with hydroxycinnamic acids (p-coumaric, caffeic and ferulic), possess 1 O 2 quenching properties. Data were obtained confirming that their acidic parent compounds were also able to quench 1 O 2 , as did polyamines (putrescine, spermidine and spermine), and that this ability depends on the number of amino groups. Potentiation of the 1 O 2 quenching ability of the conjugates relative to both parent components was established. The importance of polyamines and phenylamides in the plant non-enzymatic antioxidant defence at sites of intensive 1 O 2 generation, such as the photosynthetic centers, was suggested.
