Antitumor and antimetastatic activities of rhamnogalacturonan-II-type polysaccharide isolated from mature leaves of green tea via activation of macrophages and natural killer cells

To investigate the antitumor and antimetastatic polysaccharide from the mature leaves of green tea, GTE-II was purified using size exclusion chromatography. GTE-II consisted of 15 different sugars including rarely observed sugars such as 2-O-methyl-fucose, 2-O-methyl-xylose, apiose, aceric acid, 3-d...
