环糊精Cyclodextyin,又称“Sckardingerdertrin”,以其独特的结构和性能吸引了许多人的注意。是一种良好的药用新型包合材料。环糊精,1891年由villers所发现,在本世纪初又分离成功α及β—环糊精。于50年代初期,确定了环糊精的化学结构。1968年,美国CPC公司开始小规模生产β—环糊精,但价格昂贵1972～1973年,日本帝人公司发现制环糊精酵素(即环糊 Cyclodextyin, also known as “Sckardingerdertrin”, has attracted the attention of many people for its unique structure and properties. Is a good new medicinal inclusion materials. Cyclodextrin, discovered by villers in 1891, succeeded in isolating α and β-cyclodextrin again early this century. In the early 1950s, the chemical structure of cyclodextrins was determined. 1968, the United States CPC company began small-scale production of β-cyclodextrin, but expensive 1972 to 1973, Japan’s Teijin found that cyclodextrins enzymes (ie, cyclodextrin
