The chemical profiling of Teucrium luteum subsp. flavovirens (Batt.) Greuter & Burdet harvested on 10 stations from Southern Morocco (Errachidia), was studied for the first time. The GC and GC/MS analysis of essential oils allow the identification of 63 compounds, which represent 98.1% of the total oil composition. The main components were lemol (16.4%), -pinene (12.0%), trans-caryophyllene (7.0%), -humulene (6.4%), -pinene (5.7%), -eudesmol (5.3%). The antioxidant assays revealed a strong activity using DPPH (IC50=13.75µg/mL), FRAP (IC50=235.45µg/mL), and β-Carotene tests (IC50=275.45µg/mL). It can be concluded that this plant material has significant potential which can be used in the cosmetics industry.
Key words: Teucrium luteum subsp. flavovirens, essential oil, GC/GC-MS, antioxidant activities.
