Tea plants (Camellia sinensis) are well known for their ability to accumulate high concentrations of aluminium (Al). Aluminium distribution in tea leaves has been previously estimated on a qualitative basis using energy dispersive X-ray microanalysis (EDXMA). However, no comprehensive studies have been carried out to quantitatively determine the distribution of Al, especially in young leaves wh...

In the current work, Punica granatum L. peel, Artemisia herba-alba Asso., Matricaria chamomilla L., and Camellia sinensis extracts were used to prepare manganese dioxide (MnO2) nanoparticles utilizing a green method. Energy-dispersive X-ray (EDX) analysis, Fourier Transform Infrared Spectroscopy (FTIR) Filed emission-scanning electron microscopy (FE-SEM) analysis evaluate produced MnO2 NPs. FE-...

Effect of aqueous extracts of Ocimum sanctum and Camellia sinensis on restraint stress-induced oxidative damage in the central nervous system (CNS) of R. norvegicus were evaluated in terms of lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT). Restraint stress was used for 3h/day for 6 days consecutively, caused a significant elevation in LPO and ...

many species of tea (camellia sinensis) and cowslip (echium amoenum) are used in iranian traditional medicine. the aim of this study was to conduct the survey on the ability of iranian black tea and cowslip extracts on secretion of tumor necrosis factor-alpha (tnf-alpha) by non-infected and infected mouse macrophages. a macrophage infection model with legionella pneumophila and enzyme linked im...

Amplified fragment length polymorphism (AFLP) analysis was conducted on the wabisuke camellia and its relative species. Genetic identified among ‘Uraku’ camellia, offspring ‘Tosa-uraku’ Camellia japonica, whereas two accessions of old showed monomorphism in all fragments. The results suggested that trees are asexually-propagated clonal strains. genetic distance between cultivars Chinese camelli...

Protease was isolated from Sporosarcina RRLJ1 which was collected from acid tea (Camellia sinensis) plantations. It showed potential for production of the enzyme for commercial purposes. The study revealed that optimum pH for growth of the organism was 6.5-7 and supplement of casein (1%) in the medium was required for production of protease. Enzyme production and enzyme activity was maximum in ...

Epigallocatechin gallate (EGCG) (Figure 1a) is the major catechin component of green tea (Camellia sinensis). It has been shown to have antiviral properties against DNA viruses such as herpes simplex virus (HSV; Herpesviridae) [1], adenovirus (Adenoviridae) [2], human papilloma virus (HPV; Papovaviridae) [3], and hepatitis B virus (HBV; Hepadnaviridae) [4], and RNA viruses such as influenza vir...

Anthracnose caused by Colletotrichum is one of the most severe diseases that can afflict Camellia sinensis. However, research on the diversity and geographical distribution of Colletotrichum in China remain limited. In this study, 106 Colletotrichum isolates were collected from diseased leaves of Ca. sinensis cultivated in the 15 main tea production provinces in China. Multi-locus phylogenetic ...
