Patent number: 8002987Abstract: Provided are a stationary phase and a column using a cucurbituril-bound silica gel, and a method of separating taxane using the column. The taxane separation method includes: preparing a column for taxane separation, the column being packed with a stationary phase including a cucurbituril-bound silica gel in which a cucurbituril represented by Formula 1 or 2 is covalently bound to a modified silica gel represented by Formula 3; dissolving a taxane powder in a solvent to prepare a taxane-containing solution; applying the taxane-containing solution to the column; supplying a mobile-phase solvent to the column to obtain a taxane extract from the column; and purifying taxane from the taxane extract. Therefore, highly purified taxane can be separated from a low-purity crude taxane extract.Type: GrantFiled: March 24, 2006Date of Patent: August 23, 2011Assignee: Postech Academy-Industry FoundationInventors: Kimoon Kim, Kyeng-Min Park, Young-Ho Ko, Narayanan Selvapalam, Erumaipatty R Nagarajan
