ABSTRACT
OBJECTIVE:
To analyze the volatile components in the Eriobotrya japonica by headspace solid-phase microextraction-gas chromatography-mass spectrometry(SPME-GC-MS) and to optimize the operating conditions for SPME.METHODS:
DB-5 MS elastic silica capillary column(30.0 m?250 ?m?0.25 ?m) was used as the chromatographic column with helium of high purity(99.999%) as carrier gas at a flow rate of 1.0 mL?min-1.The injector temperature was 250 ℃;MS condition ionization mode was EI with electron energy of 70 eV and the mass scan range of 30~440 amu.RESULTS:
After headspace absorption for 30 min at 80 ℃ using 65 ?m polydimethylsiloxane-divinyl-benzene extraction head followed by desorption for 1 min at 250 ℃,the E.japonica sample was separated and identified by GC-MS analysis.A total of 34 peaks were obtained and 29 components were identified which accounted for 97.42% of the total peak area,topping the list were benzaldehyde and 4-methoxybenzaldehyde.CONCLUSION:
HS-SPME-GC-MS can be used for the rapid analysis of the volatile components in E.japonica.
