摘要

This study was conducted to examine the chemical composition and antioxidant activity of the essential oils (EOs) of Borago officinalis stem during its flowering stage. The EO composition was characterised by high proportions of E,E-decadienal, the main compound of monoterpene hydrocarbon class, with values varying from 47.08% to 55.28% in two Tunisian regions. The region of Korba exhibited the highest scavenging activity (2.05 mg/mL) by comparison with Beja region. In all tests, the fructification stage showed the best antioxidant activity of all flowering stages.
