Chemical composition, antioxidant and antibacterial activity of leaves' extracts.

is an important plant of the Rosaceae family, widely used in traditional medicine to treat various conditions such as cardiovascular diseases, cancer, diabetes, asthma, and nephritis. The aim of the current study was to assess the chemical composition, antioxidant, and antibacterial activity of leaves' extracts against The total amounts of polyphenols and flavonoids contained in the dry extracts of plants were estimated by colorimetric methods. DPPH assay was utilized to measure the antioxidant activity of .

Chemical composition and antibacterial activity of the essential oil of leaves.

Chemical composition determination and antibacterial effect of Essential Oil (EO) of leaves grown North West Algerian conditions were investigated. Antibacterial activity was evaluated by the technique of the paper disc diffusion. Extractions were carried out with Clevenger apparatus and EO compositions were investigated by gas chromatography coupled to mass spectrometry (GC-MS) analysis.
