dcterms.abstract	The invention relates to prodrugs of 8-ss-substituted estratrienes of general formula (I) in which the Z group is bonded to the steroid, method for production thereof, pharmaceutical compositions comprising said compounds and use thereof. Said compounds of general formula (I) do not bind to a- and/or ss- estrogen receptors, but to carboanhydrases and inhibit said enzymes.	-
dcterms.abstract	已有许多关于从绿茶分离(-)-EGCG的报道。然而，许多水溶性与儿茶素相似并且结构与儿茶素类似的组分的存在使得分离纯(-)-EGCG 变得困难。缺少简单、有效和廉价的获得纯(-)-EGCG的方法妨碍了在动物和人的临床研究中对(-)-EGCG进行评估。本发明提供了分离儿茶素(包括(-)-EGCG)的方法：首先将儿茶素转化成它们各自的酯形式，然后通过色谱法分离酯化的儿茶素，并将其变回到儿茶素。本发明的方法相对简单，并且可获得大量的儿茶素。	-
