In the present study, effect of polyphenol rich green tea on selected metabolic biomarkers among Asian Indian women with metabolic syndrome in normal free living condition has been recorded. Thirty three Asian Indian women (>30 y) confirmed as having metabolic syndrome, were enrolled for the present study based on written informed consent. Subjects were asked to consume three cups of green tea daily for a period of four months. Regular telephonic contact and periodic visit to supply the tea were made to ensure compliance with the intervention and maintenance of lifestyle and dietary pattern, as followed before the experimental period. Parameters analyzed at baseline have been used as control data to eliminate individual variation. Double-blind analysis of selected metabolic markers was done at baseline, 2 months and 4 months of the intervention period. At four months, a significant reduction from baseline was observed in weight (2%), waist circumference (4.5%), blood sugar (4%), glycosylated hemoglobin (4%), total cholesterol (11%) and LDL cholesterol (13%) (p < 0.01). The effect of green tea consumption on BMI, fasting insulin, HDL cholesterol, triglyceride, VLDL, C-reactive protein and homocysteine levels was either inconsistent or non significant. The present study showed that green tea consumption by free living subjects with metabolic syndrome resulted in significant improvements in some of the cardiovascular risk factors including visceral fat, blood sugar and cholesterol level.展开更多
为明确印度不同产地红茶香气关键代谢物,利用非靶向代谢组学结合顶空固相微萃取、气相色谱-质谱联用技术对印度不同产地红茶香气代谢物进行分析。结果表明,在印度红茶中共鉴定出140种香气成分,根据其化学结构分为醇类、酸类、醛类、酮...为明确印度不同产地红茶香气关键代谢物,利用非靶向代谢组学结合顶空固相微萃取、气相色谱-质谱联用技术对印度不同产地红茶香气代谢物进行分析。结果表明,在印度红茶中共鉴定出140种香气成分,根据其化学结构分为醇类、酸类、醛类、酮类、酯类、烯烃类、杂环类化合物等12类物质。大吉岭红茶醇类物质相对含量为40.58%,酯类相对含量为14.33%,显著高于阿萨姆红茶;而阿萨姆红茶中醛类(13.70%)、酮类(13.51%)和烷烃类(10.47%)等物质的相对含量均高于大吉岭红茶。感官审评结果表明,阿萨姆红茶具有甜香、清香细锐及薄荷香特征,香气持久;大吉岭红茶普遍具有甜香,个别具有花香和麝香、清香特征,T2-4红茶香气感官评分最高(94.0)。正交偏最小二乘法判别分析(orthogonal partial least squares-discrimination analysis,OPLS-DA)表明,不同产地印度红茶分别聚类到不同的区域,香气代谢物差异比较明显。香气重要贡献度因子(variable importance in projection,VIP)>1的香气代谢物有27种,包括芳樟醇、(E,E)-2,4-庚二烯醛、苯乙醛、戊酸、苯甲醛、十八烷、十三烷、(E)-6,10-二甲基-5,9-十一烯-2-酮等,其中具有香气活性(气味活性值>1)的物质包括芳樟醇、苯乙醇、苯乙醛、水杨酸甲酯、戊酸、己醛、1-甲基萘、香叶醇8种。在阿萨姆红茶中己醛、苯乙醇、戊酸、苯乙醛、1-甲基萘是区别于大吉岭红茶的关键活性香气代谢物;而大吉岭红茶中,芳樟醇、水杨酸甲酯、香叶醇是区别于阿萨姆红茶的关键活性香气代谢物。展开更多
