There are described novel glycosides of catechol estrogen, a method of preparing the same, and a medicament comprising one of the glycosides as an active ingredient. The glycosides are shown by the formula of
wherein X is carbonyl group or
R₁₀ is hydroxyl group or glycosyloxy group, and R₂ is a hydrogen atom or ethynyl group; R₁₁ is a hydrogen atom, hydroxyl group, or glycosyloxy group; R₁₂ is hydroxyl group or glycosyloxy group; and R₁₃ is hydroxyl group or glycosyloxy group,
in which glycosyloxy group is selected from the group consisting of glucosyloxy, galactosyloxy, mannosyloxy, arabinosyloxy, ribosyloxy, xylosyloxy, fructosyloxy, rhamnosyloxy, fucosyloxy, maltosyloxy, cellobiosyloxy, lactosyloxy, sucrosyloxy, maltotriosyloxy, maltotetraosyloxy, maltopentaosyloxy, maltohexaosyloxy, maltoheptaosyloxy, and sialosyloxy, and in this case, at least one of R₁₀, R₁₁, R₁₂, and R₁₃ is glycosyloxy group as defined above.
