Fractions of laurel essential oil obtained by molecular distillation with greater antioxidant and antimicrobial activities

This study aimed to analyze the chemical composition and antioxidant antimicrobial activities of Laurus nobilis L. essential oil (LEO) its fractions obtained by short-path molecular distillation. According composition, it can be said that LEO proved have activity sinceboth a high content total phenolic (TPC). Short-path distillation was used separate with superiorantioxidant activity. Laurel residue (LR) exhibited greatest activity, higher values trolox equivalent capacity ABTS radical cation (TEAC-ABTS) assay TPC. In addition, LR had lowest value IC50-DPPH. For all natural products tested an effect on foodborne pathogenic microorganisms. LEO, as well fractions, showed antimicrobial, bacteriostatic, or bactericidal against Gram-positive Gram-negative bacteria. The antimicrobials food preservatives prevent oxidation. Also, consumers considered addition in positive.
