Chemical profiling study and antioxidant activity of wild Teucrium luteum subsp. flavovirens essential oil from Morocco

The chemical profiling of Teucrium luteum subsp. flavovirens (Batt.) Greuter & Burdet (TLSF) harvested on 10 stationsfrom Southern Morocco (Errachidia) was studied for the first time. The GC and GC/MS analysis of essential oilsallow the identification of 63 compounds, which represent 98.1% of the total oil composition. The main componentswere elemol (16.4%), α-pinene (12.0%), trans-caryophyllene (7.0%), α-humulene (6.4%), β-pinene (5.7%), andγ-eudesmol (5.3%). The antioxidant assays revealed a strong activity using DPPH (IC50 = 13.75 µg/ml), Reducingpower determination (IC50 = 235.45 µg/ml), and β-Carotene tests (IC50 = 275.45 µg/ml). This plant material shows asignificant potential which can be used in the cosmetics industry.
