摘要
采用顶空固相微萃取-气相色谱-质谱(HS-SPME/GC-MS)联用方法对湖南省10种籼稻谷挥发性成分的相似性进行了研究。结果表明,该方法可以很好地分离籼稻的挥发性成分;通过对10种籼稻的GC-MS图谱分析,共确定了12个色谱峰为这10个品种籼稻挥发性成分的特征指纹峰,建立了籼稻挥发性成分的GC-MS指纹图谱,并对该图谱进行了相似度分析,结果显示10种籼稻相似度很高。建立的籼稻GC-MS指纹图谱,具有重复性和稳定性,可用于评价相关籼稻质量,为进一步研究稻谷挥发性成分提供参考。
The fingerprint on volatile constituents of indica rice was investigated using HS-SPME/GC-MS.Results showed that the volatile constituents of indica rice can be well seperated using HS-SPME/GC-MS.Based on the analysis of GC chromatogram of 10 paddy samples collected from Hunan province,it was confirmed that 12 peaks in chromatogram can be selected as the fingerprint of peaks of volatile constituents,and it was established as the fingerprint chromatogram for indica rice.Moreover,the GC fingerprint was analyzed by similarity analysis.There is a high similarity among 10 kinds of indica rice.The method is of high degree of reproducibility and satability,thus the established fingerprints could be used in quality assessment of paddy and provided helpful information for the comprehensive study of volatile consitituents of indica rice.
