The article presents information on the rules for the nomenclature of steroids. The rules of steroid nomenclature originate from a discussion held at the Chemical Industry in Basle Foundation in London, England, in 1950 among the representatives of many schools. In 1960, a group of specialists under the chairmanship of scientist T. Reichstein, including representatives of the International Union of Pure & Applied Chemistry Commissions of the Nomenclature of Organic Chemistry and of Biochemical Nomenclature, met in Basle, Switzerland, for discussions of amendments and additions to the rules. The present rule include all the original rules, mostly renumbered along with additions and amendments arising from the Basle Proposals or from current practice in the literature.
