Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The present study is focused on the antioxidant capacity and chemical profiling of eight Croatian <italic>Satureja montana</italic> 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 <italic>Folin</italic><italic>Ciocalteu</italic> 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 Fe²⁺/kg).</p> </abstract>
