Abstract
There is provided an unbranched cyclodextrin or a branched cyclodextrin inclusion complex of taxol. The complex is produced by adding an unbranched cyclodextrin of a branched cyclodextrin to taxol at a molar ratio of 1-20 times with respect to taxol. A method is provided for the improvement of the solubility of taxol in water by adding an unbranched cyclodextrin or a branched cyclodextrin thereto at a molar ratio of 1-20 times with respect to taxol. The solubility of taxol in water is improved by the present invention. A cyclodextrin inclusion complex of taxol according to the present invention serves to make taxol more easily absorbed when administered to a cancer patient, which is beneficial to cancer patients and the physiological effects of taxol may therefore be more effectively induced.
