Phenolics content and antioxidant activity of some organic extracts of endemic medicinal plant Anabasis aretioides Coss. & Moq. from Algerian Sahara

Abstract

Anabasis aretioides Coss. & Moq. is one of the endemic medicinal plants from Algerian Sahara. It's used for many traditional therapies of various diseases. In this study, we investigate the content of different organic extracts on phenolics and flavonoids, and also their antioxidant activities. Two conventional methods were used to carried out the antioxidant activity: the DPPH and hydrogen peroxide scavenging activities. From the obtained results, we found that the ethanolic extract presented the high level of phenolic and flavonoid contents (231.85 ± 20.59 mg GAE/g and 132.8 ± 24.58 mg CEQ/g). The EC50 of different extracts were arranged between 47.71 and 86.73 μg/mL. A highest hydrogen peroxide activity was observed in ethyl acetate extract compared to antioxidants used as positive control (BHA and α-tocopherol).
