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 ##STR1## wherein X is carbonyl group or ##STR2## R.sub.10 is hydroxyl group or glycosyloxy group, and R.sub.2 is a hydrogen atom or ethynyl group; R.sub.11 is a hydrogen atom, hydroxyl group, or glycosyloxy group; R.sub.12 is hydroxyl group or glycosyloxy group; and R.sub.13 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 R.sub.10, R.sub.11, R.sub.12, and R.sub.13 is glycosyloxy group as defined above.
