Analysis of Volatile Components of Propolis from Different Geographical Origins
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.
