Study on the Anti ‐Tumor Ability of Niaowangzhong Green Tea
This study revealed a potent anti‐cancer activity of this special green tea and its promising potential as chemo‐preventive agent and proper dietary practice for prevention and control of cancers.
Practical ApplicationThis study has indicated that Niaowangzhong green tea extract caused stronger cytotoxic effects on two kinds of digestive tract tumor cells HCT‐15 and MGC‐803, suggesting that as one of the most popular medicinal beverages, this green tea extract may be more suitable for treating digestive tract cancers since it can be more accessible to the locations of digestive and intestinal tracts. Therefore, thi...

Chemical Properties and Nutritional Factors of Pressed-Cake from Tea and Sacha inchi Seeds
Publication date: Available online 21 May 2016 Source:Food Bioscience Author(s): Saroat Rawdkuen, Dena Murdayanti, Sunantha Ketnawa, Suphat Phongthai A comparative study of pressed-cake made from tea and sacha inchi seeds was performed. Sacha inchi seeds contained the largest amount of protein (62.07%) and tea seeds contained the largest amount of carbohydrates (82.68%). Lysine, leucine, histidine and phenylalanine were the main essential amino acids found. High amounts of unsaturated fats with a number of omega fatty acids (ω−3, ω−6, and ω−9) were found in the residue oil following extraction. Both se...

2-DE combined with two-layer feature selection accurately establishes the origin of oolong tea
In this study, we investigated whether two-dimensional gel electrophoresis (2-DE) and nanoscale liquid chromatography/tandem mass spectroscopy (nano-LC/MS/MS) coupled with a two-layer feature selection mechanism comprising information gain attribute evaluation (IGAE) and support vector machine feature selection (SVM-FS) are useful in identifying characteristic proteins that can be used as markers of the original source of oolong tea. Samples in this study included oolong tea leaves from 23 different sources. We found that our method had an accuracy of 95.5% in correctly identifying the origin of the leaves. Overall, our me...

Tea and Risk of Age-Related Cataracts: A Cross-Sectional Study in Zhejiang Province, China.
CONCLUSIONS: Tea ingestion was associated with reduced risk of age-related cataracts. In light of these findings, we suggest that reasonable tea consumption (ie, favoring green tea and consuming an average of over 500 mL per day at moderate concentration) should offer protection against age-related cataracts.

Critical factors determining fluoride concentration in tea leaves produced from Anhui province, China.
This study investigated the fluoride present in tea plants (Camellia sinensis (L.) O. Kuntze) and its relationship to soils, varieties, seasons and tea leaf maturity. The study also explored how different manufacturing processes affect the leaching of fluoride into tea beverages. The fluoride concentration in the tea leaves was significantly correlate to the concentration of water-soluble fluoride in the soil. Different tea varieties accumulated different levels of fluoride, with varieties, Anji baicha having the highest and Nongkang zao having the lowest fluoride concentration. In eight different varieties of tea plant ha...

Association mapping of caffeine content with TCS1 in tea plant and its related specie
The objective of this study was to investigate the genetic relationship between the TCS1 and caffeine content of tea plant and its related species using association mapping. We identified 87 single-nucleotide polymorphisms (SNPs, π = 0.00447) by resequencing the TCS1 locus of 44 tea accessions. Linkage disequilibrium (LD) analysis showed that LD did not extend over the entire gene (r 2 < 0.1, within 1000 bp). Two cleaved amplified polymorphism sequence (CAPS) markers were developed from sequence variations (SNP4318 and SNP6252). By association mapping, we identified SNP4318 associated with caffeine content in ...

Green tea (-)-epigallocatechin gallate inhibits the growth of human villous trophoblasts via the ERK, p38, AMP-activated protein kinase, and AKT pathways.
This study investigated the pathways involved in EGCG modulation of trophoblast mitogenesis. EGCG inhibited trophoblast proliferation in a dose-dependent and time-dependent manner, as indicated by the number of cells and incorporation of bromodeoxyuridine (BrdU). EGCG was more effective than other green tea catechins in inhibiting cell growth. EGCG also increased the phosphorylation of the MAPK pathway proteins, ERK1/2, and p38, but not JNK. Furthermore, EGCG had no effects on the total amounts of ERK1/2, p38 MAPK, and JNK proteins. This suggests that EGCG selectively affects particular MAPK subfamilies. Pretreatment with ...

Insecticidal activity of neem oil against Gyropsylla spegazziniana (Hemiptera: Psyllidae) nymphs on Paraguay tea seedlings.
Abstract
Gyropsylla spegazziniana (Paraguay tea ampul) is one of the most important pests of Paraguay tea plants, and prohibition of synthetic insecticide use for control of this pest has led to the search for alternative methods. This laboratory study aimed to compare different control strategies for G. spegazziniana, utilizing a commercial neem seed oil product. Paraguay tea seedlings were treated with neem oil solution both pre- and post-infestation with 5th instar nymphs. The systemic action of neem oil was also evaluated by treating plant soil with the neem oil solution, followed by transfer of the in...

Coffee and tea consumption in relation to estimated glomerular filtration rate: results from the population-based longitudinal Doetinchem Cohort Study [Renal disease]
Conclusions: Coffee consumption was associated with a slightly higher eGFR, particularly in those aged ≥46 y. The absence of an association with eGFR changes suggests that the higher eGFR among coffee consumers is unlikely to be a result of glomerular hyperfiltration. Therefore, low to moderate coffee consumption is not expected to be a concern for kidney health in the general population. (Source: American Journal of Clinical Nutrition)

Molecules, Vol. 21, Pages 479: Development of an in Vitro System to Simulate the Adsorption of Self-Emulsifying Tea (Camellia oleifera) Seed Oil
In this study, tea (Camellia oleifera) seed oil was formulated into self-emulsifying oil formulations (SEOF) to enhance the aqueous dispersibility and intestinal retention to achieve higher bioavailability. Self-emulsifying tea seed oils were developed by using different concentrations of lecithin in combination with surfactant blends (Span®80 and Tween®80). The lecithin/surfactant systems were able to provide clear and stable liquid formulations. The SEOF were investigated for physicochemical properties including appearance, emulsion droplets size, PDI and zeta potential. The chemical compositions of tea seed oil and SE...
