Abstract:
OBJECTIVE: To establish the GC fingerprints for Grassleaf sweetflag rhizome aetherolea and to control its quality .METHODS: The temperature at the mouth of the sample injector was 250℃ and that of the detector was 280℃, the carrier gas was nitrogen gas and the flow rate was 1.3ml/min, the GC of aetherolea in 10 batches of Grassleaf sweetflag rhizome was analyzed by adopting temperature programming.RESULTS:Altogether 6 peaks were marked out,the sum total of the average peak area of which made up(75.4?13.7)% of the total.CONCLUSION: The method is of high degree of precision, reproducibility,stability,the resolving of each component in the aetherolea is good,the established fingerprints can be used as one of the quality control index for Grassleaf sweetflag rhizome.
