The present study described the phytochemical profile of Lavandula stoechas essential oils, collected in the area of Ain-Draham (North-West of Tunisia), as well as their protective effects against alloxan-induced diabetes and oxidative stress in rat.


Essential oils samples were obtained from the aerial parts of the plant by hydrodistillation and analyzed by GC–MS. Rats were divided into four groups: Healthy Control (HC); Diabetic Control (DC); Healthy + Essential Oils (H + EO) and Diabetic + Essential Oils (D + EO).

Antidiabetic and antioxidant activities were evaluated after subacute intraperitoneally injection of Lavandula stoechas essential oils (50 mg/kg b.w., i.p.) to rats during 15 days.


The principal compounds detected are: D-Fenchone (29.28%), α-pinene (23.18%), Camphor (15.97%), Camphene (7.83%), Eucapur (3.29%), Limonene, (2.71%) Linalool, (2.01%) Endobornyl Acetate (1.03%). The essential oils also contained smaller percentages of Tricyclene, Cymene, Delta-Cadinene, Selina-3,7(11)-diene. Furthermore, we found that Lavandula stoechas essential oils significantly protected against the increase of blood glucose as well as the decrease of antioxidant enzyme activities induced by aloxan treatment. Subacute essential oils treatment induced a decrease of lipoperoxidation as well as an increase of antioxidant enzyme activities.


These findings suggested that lavandula stoechas essential oils protected against diabetes and oxidative stress induced by alloxan treatment. These effects are in partly due to its potent antioxidant properties.
