中文摘要: 为考察不同蜜源蜂蜜挥发性成分差异，采用固相微萃取结合气相色谱与质谱联用技术对8种不同蜜源蜂蜜成分进行鉴定分析。结果表明：8种蜂蜜的挥发物中共鉴定59种挥发性化合物，椴树蜜中有30种，荆花蜜中有21种，荆条蜜中有16种，苕子蜜中有18种，洋槐蜜中有24种，野山花蜜中有27种，野酸枣蜜中有24种，枣花蜜中有32种。聚类分析结果表明，不同蜜源的蜂蜜相似度不大，通过主成分分析（principal components analysis，PCA）结果表明，壬醛和生物碱乙酸甲酯作为潜在特征标记物，可以区分不同蜜源的蜂蜜，为鉴定不同蜜源蜂蜜奠定基础。
Abstract:To analysis the difference of volatile compounds from 8 kinds of different honeys，their components were extracted and identified by headspace solid phase microextraction（HS-SPME）and gas chromatographymass spectrometry （GC-MS）.The results showed that there were 59 compounds in the volatiles of 8 kinds of honey，including 30 kinds of volatile compounds in the Linden honey，21 kinds of volatile compounds in the Jing nectar，16 kinds of volatile compounds in the chaste honey，18 kinds of volatile compounds in the chaste honey，24 kinds of volatile compounds in the acacia honey，27 kinds of volatile compounds in the wild flowers honey，24 kinds of volatile compounds in the wild jujube honey，32 kinds of volatile compounds in the Chinese date honey.The result of cluster analysis showed the similarity of honey from different honey sources was not obvious.By principal component analysis （PCA），nonanal and dasycarpidan-1-methanol，acetate could be used as potential characteristic markers to distinguish honey from different sources.The results provided the basis for distinguishing honey from different sources.
