Abstract:
Objective:To establish a method for analysis of residual organic solvents (methanol, ethanol, acetone, ethyl acetate) in Ginkgo biloba Leaves for injection.Methods: The contents of residual solvents in Ginkgo biloba Leaves for injection were determined by headspace GC on HP 5 column, with FID detector, high purity nitrogen as the carries gas.Results: There was a good linearity ( r :0.9909～0.9999). The RSD of precision and accuracy was less than 5%, the average recovery rate was in the range of 93.06%～113.78%.Conclusions: The method was simple, quick and accurate and can be used for quality control of Chinese patent medicine.
