Abstract:The volatile components in ethanolic extract of propolis (EEP) from China and Malaysia were compared by head space solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrum (GC-MS). As the results, 60 components were found in EEP from China. Curcumene, himachalene, phenylethyl alcohol, phenethyl acetate and cedrene were the major components of EEP from China. 29 components were found in EEP from Malaysia. Benzaldehyde, naphthalene, 2-pentyl furan, 2-methyl naphthalene and copaene were the major components in EEP from Malaysia. The content of volatile components in EEP from China were 10 times than that in EEP from Malaysia. In 2 types of EEP, common components, including ethanol, styrene, cedrene, benzyl alcohol and 4-ethyl-2-methoxy phenol, were found with different concentration.
