Objective To investigate the stability of compatible Quzhazhigan for injection with 0.9% sodium chloride injection， 5% glucose injection， 10% glucose injection， under four conditions. Methods Quzhazhigan for injection was mixed with 5% and 10% glucose infusions， and 0.9% sodium chloride Injection at the room temperature， 2～8℃ in dark， room temperature in dark， room temperature in strong light conditions， within 8h after which the changes of appearance， pH value， the changes of degradation products and the changes of Quzhazhigan contents in them were determined by HPLC. Results There are no significant changes in appearance， pH value of the mixture solutions， degradation products and Quzhazhigan contents in them within 8h after they were prepared at the 2～8℃ in dark， room temperature in dark conditions. Conclusion The test that prompts Quzhazhigan for injection can be mixed with the 3 infusions for clinical use within 8h at the 2～8℃ in dark， room temperature in dark conditions. And its are available for clinical use compatibility reference.
