蜂胶及杨树胶关键气味活性成分研究

Analysis of Key Aroma-Active Components of Propolis and Poplar Tree Gum

采用固相微萃取的方法提取蜂胶及杨树胶中的挥发性成分,以气相-质谱-嗅闻仪联用对蜂胶中的挥发性成分进行分离鉴定。结果测得48种气味活性成分,包括酯、醛、醇、酮和酸。蜂胶中体现花香、果香的成分较多,从而赋予其更为清香、柔和的总体气味特征。

The volatile composition of propolis and poplar tree gum was analyzed by headspace solid phase micro-extraction followed by GC-MS coupled to olfactometry. A total of 48 aroma-active compounds were identified, including esters, aldehydes, alcohols, ketones and acids. In propolis, there were many compounds responsible for the floral and fruity aroma and providing it with delicate and mellow aroma characteristics.
