61 ABSTRACT OF THE DISCLOSURE The present invention relates to novel tocopheryl oligosaccharides, acylated tocopheryl oligosaccharides, sulfated tocopheryl oligosaccharides, and antiviral agents including the sulfated tocopheryl oligosaccharides as active ingredients. In the tocopheryl oligosaccharide, the hydrogen atom of the hydroxy group at the 1-position in the terminal sugar moiety of an oligosaccharide which consists of 3 ~ 20 of identical or different repeating monosaccharide units selected from the group consisting of glucose, galactose, mannose, talose, idose, altrose, allose, glucose, xylose, arabinose, rhamnose, fucose, and fructose, which are glycoside-linked, is substituted by a tocopherol group. In the acylated tocopheryl oligosaccharides, each of any hydroxy group of the sugar moiety, other than the hydroxy group at the 1-position in the terminal sugar moiety of the oligosaccharide described above, is protected by an acyl group. The antiviral agents including the sulfated tocopheryl oligosaccharides or the biologically acceptable salt of the same as active ingredients have low toxicities and exhibit improved antiviral action, especially against the Human Immunodeficiency Virus.
