Composition of the oil and supercritical fluid CO2 extract of sweet gale (Myrica gale L.) fruits

Volatile compounds were isolated from air-dried fruits of sweet gale (Myrica gale L.) using supercritical fluid extraction with CO2 (SFE) and simultaneous distillation and extraction (SDE) micromethod. Extracts were analyzed using GC/FID and GC/MS methods. Sixty compounds were identified representing over 90% of the oil, of which 1,8-cineole (25.7%) and alpha-pinene (20.6%) were the major components. Two flavonoid compounds were identified in SFE extracts. The composition of SFE extracts under mild conditions did not have great distinctions compared with SDE.
