Chemical Make-up of Green Tea Liquor

Effects of Green Liquor Pretreatment on the Chemical Composition and Enzymatic Hydrolysis of Several Lignocellulosic Biomasses

Pretreatment of biomass is an extremely important step in a commercial biorefinery. For realization of lignocellulosic biomass as an alternative fuel source to occur, a fundamental understanding and critical investigation of the chosen pretreatment are essential. In this work, green liquor (GL) pretreatment of four plant species, namely Masson pine, poplar, moso bamboo, and miscanthus, was inve...

The effects of whole green tea infusion on mouse urinary bladder chemical carcinogenesis

Objective(s):Green tea (GT) is one of the most popular beverages worldwide whose beneficial effects on health have been demonstrated. Recent studies suggest that GT may contribute to reduction of cancer risk and progression. The aim of this study was to evaluate the effects of whole GT on urinary bladder chemical carcinogenesis in male and female ICR mice. Materials and Methods: The GT charact...

Green tea: a tea or a remedy?

Green tea polyphenol sensing

Green tea polyphenols have emerged over the past two decades as an important dietary factor for health promotion. There is considerable evidence that tea polyphenols, in particular (-)-epigallocatechin-3-gallate (EGCG) inhibit carcinogenesis. However, the mechanisms for the cancer-preventive activity of EGCG are not completely characterized and many features remain to be elucidated. Recently we...

Green tea gets molecular.

Green tea and its major polyphenolic flavonoid, epigallocatechin gallate (EGCG), have been credited with cancer chemopreventive activity for many years; the mechanism for this activity, however, has remained obscure. Now, as reported in this issue of the journal (beginning on page 1366), Urusova and colleagues showed direct binding of EGCG to the peptidyl prolyl cis/trans isomerase Pin1, which ...
