Study on the Chemical Components of Volatile Oils from Tongling Ginger by GC-MS

[Objective] To study ginger volatile oil from Tongling and provide theoretical basis for development and utilization.[Method] Using gas chromatography mass spectrometry,Tongling ginger essential oil components were separated and identified and each component content was calculated by the method of peak area normalization.[Result] 12 major ingredients were identified,accounting for 67.356% of the total volatile oil content,and 5 ingredients were first found in ginger.In addition,zingiberene was the highest content,up to 16.730%.[Conclusion] The results indicated that Tongling ginger was different in category and content of their chemical composition from other producing areas ginger,which has the development and utilization value.
