Abstract：The method of IR was used to study GB spectrum variety with different water ratio, and it was showed that GB IR spectrum only changed in the absorption strength at 3 452, 1 793, 1 780 and 1 630 cm-1. The reason is that the water was concealed by GB cage skeleton and formed hydroxyl bond with GB hydroxyl groups, and the structure of GB remained unchanged and accorded with standardized GB. With the help of DSC and LC-MS, the subtle relations between GB and water were explained, GB is lipophilic and can not be dissolved by water, but in general, GB is easy to absorb the water of environment, and can be dehydrated under particular conditions.
