Abstract: A saccharide derivative represented by Chemical Formula (1) or (2), or a salt thereof, includes units of a monosaccharide linked to each other in a chainlike or cyclic manner through glycosidic bonding and has antimicrobial action. In the formulae, R1 represents an amino-containing structure; and n represents an integer of 3 or more. A saccharide derivative represented by Chemical Formula (5) or (6), or a salt thereof, includes units of a monosaccharide linked to each other in a chainlike or cyclic manner through glycosidic bonding and has antimicrobial activity enhancing action. In the formulae, R3 represents an amino-containing structure; R4 is selected from acetyl and propanoyl; and n represents an integer of 3 or more.
