Proanthocyanidins in unripe Manilkara zapota (chiku) were isolated using solvent extraction followed by Sephadex LH-20 fractionation with a yield of 0.9%. HPLC analysis using a diol column revealed well-resolved oligomers ranging from dimer to hexamer. The majority of the proanthocyanidins

With the aim of enhancing G-quadruplex binding activity, two new glucosaminosides (16, 18) of penta-methylated epigallocatechin were synthesized by chemical glycosylation. Subsequent ESI-TOF-MS analysis demonstrated that these two glucosaminoside derivatives exhibit much stronger binding activity to human telomeric DNA and

Metabolic profiles of broiler chickens were examined after the ingestion of green tea, tea polyphenols, and (-)-epigallocatechin-3-gallate (EGCG). Solid-phase extraction of serum and litters yielded free catechins and their metabolites, which were then identified and quantified by liquid chromatography-tandem mass
