Abstract:

In this work, propolis essential oil was obtained by steam distillation extraction and supercritical CO2 extraction, respectively. Added together, 50 components in resulting propolis essential oils were identified by GC-MS method. Propolis essential oils extracted by both methods exhibited strong inhibition effects against Staphylococcus aureus, Bacillus subtilis and Pseudomonas aeruginosa in vitro. Stronger inhibition effect of propolis essential oil extracted by supercritical CO2 extraction on the three species of bacteria than that of propolis essential oil extracted by steam distillation extraction was observed.

Key words: supercritical CO2 extraction, steam distillation extraction, propolis, antibacterial activity
