PHYTOCHEMICAL SCREENING, ANTIBACTERIAL AND ANTIOXIDANT ACTIVITIES OF Ocimum Basilicum L. CULTIVATED IN BISKRA, ALGERIA

Abstract

Algerian flora contains a wide range of aromatic plants of great therapeutic interest thanks to their biologically active secondary metabolites which makes them a subject of scientific interest. In this work, we were interested in Ocimum basilicum L. of Lamiaceae family cultivated and harvested in Biskra city located at South-East of Algeria. Phytochemical screening has been performed to reveal the presence of flavonoids, tannins, coumarins, essential oil, and other phytochemicals. The contents of total polyphenols, total flavonoids and total tannins have been determined. The obtained essential oil and extracts have been the subject of antibacterial and antioxidant assays. Our outcomes confirmed that Ocimum basilicum L. has a multiplicity of potential phytochemicals with a considerable amount and can be used as an alternative natural source of antioxidant and antibacterial components.
