Obesity is a one of the main global public health problems associated with chronic diseases such as coronary heart disease, diabetes and cancer. As a solution to obesity, we suggest Plantago albicans, which is a medicinal plant with several biological effects. This study assesses the possible anti-obesity protective properties of Plantago albicans in high fat diet-fed rats. 28 male Wistar rats were divided into 4 groups; a group which received normal diet (C), the second group was fed HDF diet (HDF), the third group was given normal diet supplemented with Plantago albicans (P.AL), and the fourth group received HDF supplemented with Plantago albicans (HDF + P.AL) (30 mg/kg/day) for 7 weeks. Our results showed an increase in body weight of HDF rats by ∼16% as compared to the control group with an increase in the levels of total cholesterol (TC) as well as LDL-cholesterol, triglycerides (TG) in serum. Also, the concentration of TBARS increased in the liver and heart of HDF-fed rats as compared to the control group. The oral gavage of Plantago albicans extract to obese rats induced a reduction in their body weight, lipid accumulation in liver and heart tissue, compared to the high-fat diet control rats. The obtained results proved that the antioxidant potency of Plantago albicans extracts was correlated with their phenolic and flavonoid contents. The antioxidant capacity of the extract was evaluated by DPPH test (as EC50 = 250 ± 2.12 μg/mL) and FRAP tests (as EC50 = 27.77 ± 0.14 μg/mL). These results confirm the phytochemical and antioxidant impact of Plantago albicans extracts. Plantago albicans content was determined using validated HPLC methodology.
