| Abstract: | "The present study is focused on the antioxidant capacity and chemical profiling of eight Croatian Satureja montana L. honey samples. Among the 20 compounds obtained by headspace solid-phase microextraction (HS-SPME) and identified by GC-FID and GC/MS analyses, hotrienol was predominant (75.9-81.7%). The honey matrix volatile/semivolatile profile was investigated by ultrasonic solvent extraction (USE) followed by GC-FID and GC/MS analyses. The major compounds identified by this latter method were the sinapic-acid derivatives methyl syringate (36.2-72.8%) and syringaldehyde (2.2-43.1%). Direct, targeted HPLC-DAD analyses of the native honey samples revealed the presence of methyl syringate (7.10-39.60 mg/kg) and syringic acid (0.10-1.70 mg/kg). In addition, the total phenolic content of the samples was determined by the Folin?╖?Ciocalteu assay (311.0-465.9 mg GAE/kg), and the antioxidant capacity was evaluated by the DPPH radical-scavenging activity (0.5-1.0 mmol TEAC/kg) and the ferric reducing antioxidant power (2.5-5.1 mmol Fe(2+) /kg)" |
