摘要
采用顶空固相微萃取-气质联用技术分析5个省(安徽、吉林、河北、河南、甘肃)37个蜂胶样品的挥发性成分。结果共测出49种化合物,包括醇、酯、醛以及萜烯类化合物;对37个蜂胶样品的挥发性组分的相对含量进行主成分分析,结果通过这种方法能够对不同地域的蜂胶进行一定的区分,其中甘肃省的蜂胶样品与其他4省的差别最大,而河南、河北和安徽3省的蜂胶样品未能区分开。
The volatile components of 37 propoli samples from five provinces (Anhui, Jilin, Hebei, Henan and Gansu) in China were analyzed by headspace solid phase micro-extraction combined with gas chromatography-mass spectrometry (HS-SPME-GC-MS). A total of 49 compounds were identified including alcohols, esters, aldehydes and terpenoids. The relative contents of the components were analyzed by principal component analysis (PCA). The results showed that propoli samples from different regions could be discriminated by this method. Gansu samples exhibited the largest difference from samples from other four provinces. However, samples from Hebei, Henan and Anhui could not be discriminated.
