Analysis on Volatile Constituent of Ocimum basilicum Based on Gas Chromatography-Mass Spectrum

[Objective] The aim was to detect volatile constituent of Ocimum basilicum.[Method] The gas chromatography-mass spectrum technology was used to analyze the volatile constituent of Ocimum basilicum.[Results] 53 chemical compositions were identified,among which estragole occupied most(64.55%),followed by methyl eugenol(12.16%),1,8-Cineole(8.355%),T-cubebol(1.50%),E-asarin(1.412%),(E)-β-ocimene(1.028%).[Conclusion] Volatile constituent of Ocimum basilicum were complex,among which 4 kinds of ethers compounds occupied 74.455%,3 kinds of phenol compounds accounted for 12.208%,22 kinds of alkene occupied 5.401%,9 kinds of alcohol compounds accounted for 1.751%,and there were also few ketones,the ester,the acids material and so on.
