Novel antioxidants, derivatives of trolox, and selected phenolic acids have been prepared in good yields and fully characterized by 1H NMR, 13C NMR, and MS. Their antioxidant activities have been assessed by DPPH and ORAC assays, and during frying and accelerated storage tests. Novel phenolic compounds exhibited higher radical scavenging activities than both trolox and R-tocopherol. Trolox hydroxybenzoate showed a significantly higher protection than R-tocopherol under storage conditions. All new antioxidants performed better than R-tocopherol under frying conditions. Moreover, their outstanding thermal stability makes them more valuable than R-tocopherol for frying applications.

scheme or table, p. 1355 - 1363 (2011/01/04)
Heterodimers were synthesized of pharmacologically important α-tocopherol synthetic analogs with triterpene acids(betulonic, betulinic), potential polyfunctionsl drugs possessing antioxidant activity. The combination of the fragments of biologically active substances was performed through linkers (residues of succinic acid, hydrazine, glycine, tetramethylenediamine) binding the side chain of the antioxidant molecule with atoms C3 or C28 of the terpenoid.
