This review summarizes published in vitro, animal, and clinical studies investigating the effects of green tea (Camellia sinensis) extract and associated catechins on drug-metabolizing enzymes and drug transporters. In vitro studies suggest that green tea extract and its main catechin, (-)-epigallocatechin-3-gallate, to varying degrees, inhibit the activity of CYP1A1, CYP1A2, CYP2B6, CYP2C8, CY...

More than 20% of the world's biodiversity is located in Brazilian forests and only a few plant extracts have been evaluated for potential antibacterial activity. In the present study, 705 organic and aqueous extracts of plants obtained from different Amazon Rain Forest and Atlantic Forest plants were screened for antibacterial activity at 100 microg/ml, using a microdilution broth assay against...

Nowadays, consumers are highly worried about using chemical preservatives in foods. Thus they tend to use natural and safe food products with healthful benefits. Pomegranate and its peel can have such a role. This study aimed to determine the antioxidant activity, Total Phenolics, and Flavonoids Properties of Different Parts of Pomegranate extracts. Three types of extracts were prepared with di...

Introduction and objective: Otitis externa, commonly called ear disease, is characterized by inflammation of the external ear canal. The aim of this study was to evaluate the antimicrobial potential of Cassia fistula flowers, leaves and bark extracts against Staphylococcus aureus, Proteus mirabilis, Escherchia coli, Pseudomonas aeruginosa, Acinetobacter sp., and Candida albicans, pathogens caus...

The purpose of this study was to evaluate the beneficial effects of organic and conventional grapevine (Vitis labrusca L.) leaf extracts in reducing hydrogen peroxide-induced stress in the liver, heart and kidney of Wistar rats by measuring lipids and proteins damages (carbonyl assay), as well as the activity of the antioxidant enzymes superoxide dismutase and catalase. The preincubation with 5...

Life-detection instruments on future Mars missions may use surfactant solutions to extract organic matter from samples of martian rocks. The thermal and radiation environments of space and Mars are capable of degrading these solutions, thereby reducing their ability to dissolve organic species. Successful extraction and detection of biosignatures on Mars requires an understanding of how degrada...

[1] To study cycling of organic fractions in the ocean, relative abundances and radioand stable-carbon isotope measurements of total lipid extract, acid-soluble, and acidinsoluble fractions of suspended particulate organic carbon (POC) were made. Changes in relative abundances occurred mostly in the upper 1000 m of the water column, with a decrease in total lipid extract and the acid-soluble fr...

Organic fertilizers are generally thought to be an effective way to sustain soil fertility and plant growth. To promote the productivity of chrysanthemum, five sources of liquid organic fertilizers (L1–L5), as well as a chemical fertilizer, were applied at an early stage of the growth cycle to investigate their effects on plant growth. In the short-term pot experiment, the liquid organic fertil...

Extacts of root of Glycyrrhiza glabra linn were prepared by using n-hexan, toluene, tetrahydrofuran, ethylacetate, and ethanol and their antioxidant and antimicrobial activities were measured. Secondary metalbilites like flavonoids, alkaloids, terpenoids, glycosides, and steroids were measured and it was found that highly polar solvents ike ethyl alcohol, ethyl acetate and THF extract more meta...
