Available online 22 June 2016 Edited by D De Beer Antimutagenesis studies against the tobacco-specific mutagens 4-(methylnitrosamino)-1-(3-pyridyl)-1butanone (NNK) and N-oxide, 4 (methyl-nitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), were conducted using hot water aqueous extracts of rooibos (Aspalathus linearis), honeybush (Cyclopia intermedia), and cancer bush (Sutherlandia frutescens). Aqueous...

tea leaves contain unsaturated fatty acids, key precursors of volatile compounds contributing to tea aroma quality. tea is cultivated in areas with diverse environmental conditions. nitrogenous fertilizers influence tea yields and quality. a previous single site study demonstrated that increasing nitrogenous fertilizer rates raised fatty acid levels. however it is not known if the magnitudes an...

influence of arbuscular mycorrhizal fungi (amf) (glomus etunicatum, g. intraradices and glomus versiforme) and external phosphorus supplement (8 and 35 mg p kg-1 soil) on leaf p, zn, cu and fe nutrition of 4-month-old tea(camellia sinensis) was studied in an glass house pot experiment. the highest leaf p concentration (up to 59.43% increase) was found in g. versiforme inoculated seedlings gro...

Background: Acanthamoeba is a resistant protozoan that causes severe diseases, such as GAE and CAK. Because many medications are ineffective on the parasite, the quest to find alternative drugs is in progress. Objective: This research was aim 13 ed to assess the performance of the black and green tea extracts on Acanthamoeba. Methods: The clinical isolate of Aca...

This study sought to investigate the effect of infusions from green tea (Camellia sinensis) and some citrus peels [shaddock (Citrus maxima), grapefruit (Citrus paradisi), and orange (Citrus sinensis)] on key enzymes relevant to the management of neurodegenerative conditions [monoamine oxidase (MAO) and butyrylcholinesterase (BChE)]. The total phenol contents and antioxidant activities as typifi...

In this study, we used several molecular techniques to develop a fast and reliable protocol (DNA Verity Test, DVT) for the characterization and confirmation of the species or taxa present in herbal infusions. As a model plant for this protocol, Camellia sinensis, a traditional tea plant, was selected due to the following reasons: its historical popularity as a (healthy) beverage, its high selli...

a r t i c l e i n f o Fuzhuan tea is a traditional preparation of Camellia sinensis L. (Theaceae) from Hunan, China, that is fermented with the fungus Eurotium cristatum. Metabolomic analysis was performed on fuzhuan tea extracts and compared to extracts of non-fermented green teas using ultra-performance liquid chromatography/time of flight-mass spectrometry (UPLC-ToF-MS). Principal component ...

The development in Indonesia is still focused on increasing productivity and until now there has been no study the level genetic similarity based quality characters. Therefore, purpose this was to ex...

The plant, Camellia sinensis (leaves) is popularly known for its usage as tea in many parts of the world, including Nigeria. purpose this study was to screen bioactive compositions and determine endogeneous antioxidant potentials fresh processed (tea) C. aqueous leaf extract. Phytochemicals, minerals vitamins analysis were carried out following standard procedures. extracts further administered...
