Tea polysaccharides from Camellia sinensis: chemical analysis, structural characterization, and inhibition of HeLa cells activity

Tea polysaccharides (TPS) were analyzed and characterized by HPAEC, GPC, FT-IR, AFM, HSQC, and HMBC NMR as well as methylation. The TPS mainly consisted of neutral (F0, F0.2, and F0.3) and acidic p...
