Flavonoids are ubiquitous in photosynthesising cells and are commonly found in fruit, vegetables, nuts, seeds, stems, flowers, tea, wine, propolis and honey. For centuries, preparations containing these compounds as the principal physiologically active constituents have been used to treat human diseases. Increasingly, this class of natural products is becoming the subject of anti-infective rese...

Phytomedicine such as tea tree (melaleuca) oil have become increasingly popular in recent decades. This essential oil has been used for almost 100 years in Australia but is now available worldwide both as neat oil and as an active component in an array of products. The primary uses of tea tree oil have historically capitalized on the antiseptic, antifungal, antiviral and anti-inflammatory actio...

Methods A new series of Nheterocyclic compounds has been derived from benzimidazole and pyrimidine nuclei optimized with the Discovery studio 3.0 software to investigate the interactions between the target compounds and the amino acid residues of Escherichia coli PDF Ni (PDB: ID 1G2A), and then synthesized. Further, all compounds were examined for their antibacterial activities against Gram-pos...

Plant essential oils are widely used as fragrances and flavours in the cosmetic, perfume, drug and food industries. Oxygenated monoterpenes are widespread components of the essential oils, usually occurring in high amount. In this paper, the antibacterial activities of twenty-one oxygenated monoterpenes (borneol, borneol acetate, camphor, carvone, 1,8-cineole, citronellal, beta-citronellol, dih...

PURPOSE Two plant essential oils (EOs), including those from Heracleum transcaucasicum and Heracleum anisactiss (Umbeliferae) were studied to detect the chemical constituents and evaluated for their antibacterial activities against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli and Pseudomonas aeruginosa. METHODS The EOs of H. transcaucasicum and H.anisactis (Apiacae) wer...
