摘要：
This invention relates to Alpha -glucosides of steroids containing hydroxy groups in both the 16 Alpha - and 17-positions and the method for preparing them by reacting with a polysaccharide or an oligosaccharide, such as maltose, in the presence of a source of the enzyme: amylase or transglucosylase. The Alpha -glucosides are new compounds that possess estrogenic activity. They may be used, therefore, as antifertility agents.
