    • The present invention relates to a method for preparation of androst-4-ene-3,17-dione (AD) and androsta-1,4-diene-3,17-dione (ADD). More particularly, the present invention relates to a method for preparing AD/ADD, comprising the steps of: (a) heating sterols and emulsifier respectively, to dissolve completely and mixing to prepare a mixture; (b) placing the mixture in a water bath at 70˜90° C. and stirring to obtain emulsified sterols; and (c) adding the emulsified sterols to culture media of microorganism as a component. And the present invention relates to a method for preparing AD/ADD, comprising the addition of cyclodextrin-sterol complexes extracted from milk to culture media of microorganism as a component. The emulsified sterols and cyclodextrin-sterol complexes adopted in the present invention can be easily prepared and be effectively used for obtaining AD/ADD at a high yield.
    • 雄甾-4-烯-3,17-二酮(AD)和雄甾-1,4-二烯-3,17-二酮(ADD)的制备方法技术领域本发明涉及雄甾-4-烯-3,17-二酮(AD)和雄甾-1,4-二烯-3,17-二酮(ADD)的制备方法。 更具体地说,本发明涉及一种制备AD / ADD的方法,包括以下步骤:(a)分别加热固醇和乳化剂以完全溶解并混合以制备混合物; (b)将混合物置于70〜90℃的水浴中并搅拌,得到乳化甾醇; 和(c)将乳化的甾醇加入作为组分的微生物培养基中。 本发明涉及AD / ADD的制备方法,其特征在于,将从乳中提取的环糊精 - 甾醇配合物添加到微生物的培养基中作为成分。 本发明中采用的乳化甾醇和环糊精 - 固醇配合物可以容易地制备并且有效地用于以高产率获得AD / ADD。
