background: in current study, chemical composition and antibacterial activity of leaves and flowers essential oils of origanum vulgare ssp. gracile against four food-borne pathogens including  escherichia coli, listeria monocytogenes, salmonella thyphimurium and staphylococcus aureus were examined. methods: the different organs (leaves and flowers) of o. vulgare ssp. gracile were harvested at f...

phytochemicals are good sources of natural antioxidants and have beneficial effects on human health. many of phenolic phytochemicals have shown antimicrobial and antifungal activity. anise hyssop ( agastache foeniculum [pursh] kuntze ) is a perennial aromatic plant of the lamiaceae family with antimicrobial and antifungal properties and useful for gastrointestinal problems. in this investigatio...

Plants are recognized in the pharmaceutical industry for their broad structural diversity as well as their wide range of pharmacological activities. The biologically active compounds present in plants are called phytochemicals. These phytochemicals are derived from various parts of plants such as leaves, flowers, seeds, barks, roots and pulps. These phytochemicals are used as sources of direct ...

Phytochemicals are biologically active compounds, found in plants in small amounts, which are not established nutrients but which nevertheless seem to contribute significantly to protection against degenerative disease. At present, most interest in phytochemicals is focused on the polyphenolic flavonoids and on the carotenoids, although allium compounds, glucosinolates, indoles and coumarins ha...

A wide variety of phytochemicals are consumed for their perceived health benefits. Many of these phytochemicals have been found to alter numerous cell functions, but the mechanisms underlying their biological activity tend to be poorly understood. Phenolic phytochemicals are particularly promiscuous modifiers of membrane protein function, suggesting that some of their actions may be due to a co...

The nervous system is of fundamental importance in the adaptive (hormesis) responses of organisms to all types of stress, including environmental "toxins". Phytochemicals present in vegetables and fruits are believed to reduce the risk of several major diseases including cardiovascular disease, cancers and neurodegenerative disorders. Although antioxidant properties have been suggested as the b...

The objective of this study was to determine the effects of muscadine grape or wine (cv. Noble) phytochemicals on obesity and associated metabolic complications. Muscadine grape or wine phytochemicals were extracted using Amberlite FPX66 resin. Male C57BL/6J mice were given a low-fat diet (LF, 10% kcal fat), high-fat diet (HF, 60% kcal fat), HF + 0.4% muscadine grape phytochemicals (HF+MGP), or...

It is generally accepted that nutritional behaviors constitute decisive components of human health. Phytochemicals (small, nonenergetic molecules of vegetal origin) are overall inhibitory on the expression of gene products promoting proliferation and resistance to apoptosis. On the contrary, phytochemicals stimulate the synthesis of adaptive proteins that favor resistance to cellular stress (de...

Phytochemicals are an important part of traditional medicine and have been investigated in detail for possible inclusion in modern medicine as well. These compounds often serve as the backbone for the synthesis of novel therapeutic agents. For many years, phytochemicals have demonstrated encouraging activity against various human cancer models in pre-clinical assays. Here, we discuss select phy...

Phytochemicals are potential cancer chemopreventive agents, based partly on cellular research establishing that phytochemicals inhibit the proliferation of cancer cells. To elucidate the mechanism of phytochemicals, a basic understanding is needed of what stimulates cancer cell proliferation. Cancer cells, particularly those that are highly invasive or metastatic, may require a certain level of...
