Nowadays different foods and vegetables are contaminated with oxalates of sodium and calcium, present in pesticides and chemical fertilisers. Even many drugs contain sodium oxalate, which is a causative agent of urolithiasis and hepatic cell damage. Herbal plant supplements may reduce this drug induced toxicity. Renal and hepatoprotective effects of the aqueous extracts of green tea (Camellia s...
Plant extracts have been widely used as topical applications for wound-healing, anti-aging, and disease treatments. Examples of these include ginkgo biloba, echinacea, ginseng, grape seed, green tea, lemon, lavender, rosemary, thuja, sarsaparilla, soy, prickly pear, sagebrush, jojoba, aloe vera, allantoin, feverwort, bloodroot, apache plume, and papaya. These plants share a common character: th...
1-Phenylethanol (1PE) is a major aromatic volatile in tea (Camellia sinensis) flowers, whereas it occurs in a much smaller amounts in leaves. Enzymes involved in the formation of 1PE in plants and the reason why 1PE differentially accumulates in plants is unknown. In the present study, enzymes in the last step leading from acetophenone to 1PE were isolated from tea flowers by traditional bioche...
PURPOSE Thirty-five commercially available Camellia sinensis (black and green) and herbal leisure teas and an assortment of Traditional Chinese medicinal teas were randomly selected and examined for their potential to inhibit the drug metabolizing enzyme cytochrome P450 3A4 (CYP3A4). The study was then extended to examine CYP2D6*1 and CYP2D6*10. METHODS Microtiter fluorometric assays were uti...
Green, black and white teas are all produced from leaves and shoots of Camellia sinensis, the only difference is how they are processed. The aim of this study was to compare the total phenols and flavonoid contents and antioxidant capacity of green, black and white tea bags of different brands. The morphodiagnosis of leaves was used to identification of plant material. HPLC-DAD fingerprinting c...
In this study, the chemical constituents of pu-erh tea, black tea, and green tea, as well as those of pu-erh tea products of different ages, were analyzed and compared using a chemical profiling approach. Differences in tea processing resulted in differences in the chemical constituents and the color of tea infusions. Human biological responses to pu-erh tea ingestion were also studied by using...
This research involved in and coordinated multidisciplinary and complementary natural resources in the area of sustainable soil and plant nutrient management as well as economic benefits of edible herb production systems. The main concern was selection of the right growing media to achieve optimum yield and growth rate while avoiding application of synthetic fertilizers.Froriepia subpinnata is ...
Compost tea describes a procedure where compost is mixed with water. The mixture may be left to stand with minimal disturbance, also called “compost extract” or “steepage”, or actively supplied with oxygen by an aquarium pump to stimulate population growth of aerobic microbes. This project examined actively aerated compost tea. Over a 3-year period, 25 experiments were conducted where a standar...
Introduction: Vaginitis is an inflammatory and infectious disease in human host that involved vaginal mucosa. Increase of resistance to various antibacterial agent has been very significant in three or four recent decades and this important subject reveals the use of new and natural sources such as plants with medical and antimicrobial property for eradication of these infections. Therefore, th...
BACKGROUND Plant polyphenols are known for their limiting of adverse effects on reactive oxygen species (ROS) in biological systems. The photochemiluminescence (PCL) assay allows to evaluate the antiradical activity of a compound in the presence of a superoxide anion-radical (O •-), which is one of the ROS directly associated with the human body. In this work, determination of the superoxide an...
