摘　　要：五倍子蜂蜜是一种特色中草药蜂蜜,是重庆地区秋季主要蜜种,对发展农村经济、促进农民增收有着重要价值。该研究采用顶空-固相微萃取结合气相色谱质谱联用技术对重庆市6个产地的五倍子蜂蜜挥发性成分进行分析。结果表明,从五倍子蜂蜜中共鉴定出83种挥发性化合物,主要包括17种醇类、10种酯类、13种醛类、11种酮类、6种萜烯类、16种烷烃类等,香气活度值>1的化合物共有20种。不同产地样本之间挥发性物质组成存在差异,采用化学计量学分析筛选出反-α,α-5-三甲基-5-乙烯基四氢化-2-呋喃甲醇、橙花醚、二十烷、苯乙醛、壬醛、庚醛、叔丁基对苯醌和十一醛等17种化合物对五倍子蜂蜜地理来源判别模型及独特风味有贡献。绘制聚类热图,发现这17种差异化合物能够进一步将不同组样本区分开,可能作为判别重庆市五倍子蜂蜜地理来源的指标。该研究揭示了重庆市五倍子蜂蜜的挥发物组成和香气特征,为重庆市特色五倍子蜂蜜的开发提供理论支持。Rhus chinensis honey,a distinctive Chinese herbal honey predominantly produced in Chongqing during autumn,holds significant value in fostering rural economic growth and augmenting the incomes of farmers.This research employed headspace-solid phase microextraction coupled with gas chromatography-mass spectrometry(HS-SPME-GC-MS)to analyze the volatile components of Rhus chinensis honey from six Chongqing-based production regions.The findings revealed 83 volatile compounds,including 17 alcohols,10 esters,13 aldehydes,11 ketones,6 terpenes,and 16 alkanes.Notably,20 of these compounds possessed odor activity values exceeding 1.Variations in volatile compositions were observed among samples from different locales.Chemometric analysis techniques,specifically designed to analyze complex data sets,were applied to identify 17 compounds,such as trans-linalool oxide,2-methoxynaphthalene,eicosane,phenylacetaldehyde,nonanal,heptanal,2-tert-butyl-1,4-benzoquinone,and undecanal,that contributed significantly to the geographical origin discrimination model and unique flavor profile of Rhus chinensis honey.A cluster heat map was created,highlighting how these 17 compounds could effectively distinguish between different sample groups and potentially serving as markers for identifying the geographical origin of Chongqing Rhus chinensis honey.This study sheds light on the volatile composition and aroma characteristics of Chongqing Rhus chinensis honey,thereby providing theoretical foundations for the development of unique Rhus chinensis honey product in this region.
