This research highlights the chemical composition, antioxidant and antibacterial activities of essential oils and various crude extracts (using methanol and methylene chloride) from Syzygium cumini leaves. Essential oils were analyzed by gas chromatography-mass spectrometry (GC-MS).The abundant constituents of the oils were: α-pinene (32.32%), β-pinene(More)
Aromatic gum from Boswellia carteri (olibanum oleogum) has long been used in Egyptian traditional medicine. Cyclooxygenase-1 (COX-1) enzyme inhibitory assay guided purification of the extracts of this resin resulted in five bioactive compounds, 3alpha-O-acetyl-8,24-dien-tirucallic acid (1), verticilla-4(20),7,11-triene (2), cembrene A (3), incensole acetate(More)
The present work was undertaken to evaluate the polyphenolic content, antioxidant and antiviral properties of two wild medicinal plants; Achillea fragrantissima and Nitraria retusa. The crude extracts of both plants were prepared using methanol and ethyl acetate solvents. Generally, total phenolic content ranged from 0.31 to 15.05 mg gallic acid equivalents(More)
