The structural features of rehmannan SA, a polysaccharide with remarkable reticuloendothelial system-potentiating activity obtained from the root of Rehmannia glutinosa, were investigated by methylation analysis and periodate oxidation. Rehmannan SA is mainly made up of arabino-3, 6-galactan type structural units. Both rehmannan SA and rehmannan SB showed pronounced anti-complementary activity.
