Composition of Seed Flour of Selected Nigerian Tea (Camellia sinensis) Clones – A Comparative Study
In the present article, six clones of Nigerian Tea (Camellia sinensis) were selected for comparative study. Proximate, phytochemical and functional characterization of the whole Tea seed flour (TSF) was examined. The characteristics of the expressed oil from the seed of the different clones were also carried out. Results shows that oil content ranged between 22.9% (C318) to 28.9% (C228...
متن کاملElucidation of Differential Accumulation of 1-Phenylethanol in Flowers and Leaves of Tea (Camellia sinensis) Plants.
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...
متن کاملAccumulation and distribution of aluminium and other elements in tea (Camellia sinensis) leaves
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...
متن کاملExpression of caffeine biosynthesis genes in tea (Camellia sinensis).
Using semi-quantitative reverse transcription-PCR, we studied the expression of genes encoding caffeine synthase (TCS1), inosine-5'-monophosphate dehydrogenase (TIDH), S-adenosyl-L-methionine synthase (sAMS), phenylalanine ammonia-lyase (PAL) and alpha-tubulin (Tua1) in young and mature leaves, stems and roots of 4-month-old tea seedlings and young and old tea tissue cultures. The amounts of tr...
متن کاملChemopreventive effect of green tea (Camellia sinensis) among cigarette smokers.
Chemopreventive effects of green tea and coffee among cigarette smokers were examined in 52 clinically healthy male subjects between 20 and 52 years of age. Blood specimens were obtained from nonsmokers (group I), smokers (group II), smokers consuming green tea (group III), and smokers drinking coffee (group IV). The mean number of cigarette smoking years (> 10 cigarettes/day) in groups II-IV r...
