Analysis of Volatile Organic Compounds in 6 Garden Plants
To investigate the composition of volatile organic compounds(BVOCs)in 6 normal nursery plants in Beijing,we utilized powerful headspace stowing assortment and warm desorption-gas chromatography-mass spectrometry(TDS-GC-MS)to BVOCs in Platycladus orientalis,Cedrus deodara,Taxus cuspidata,Ginkgo bi-loba,Syringa beijingensis and Rosa chinensis.We also uesd particle top region standardization to normalize the peak areas of volatile organic compounds released from plants as a percentage to gauge the overall items in com-pounds.The results showed that the BVOCs released from P.orientalis included 8 classes of 62 species,C.deodara BVOCs included 8 classes of 64 species,T.cuspidata BVOCs included 7 classes of 65 species,G.bi-loba BVOCs included 8 classes of 56 species,S.beijingensis BVOCs included 8 classes of 57 species,and R.chinensis BVOCs included 9 classes of 56 species.All 6 nursery plants contained 7 sorts of builds including:ol-efins,alkanes,fragrant hydrocarbons,alcohols,aldehydes,ketones,and esters.However the general items in each kind of build differed significantly.All of them contained 5 common components of(+)-α-pinene,(+)-limonene,toluene,hexanal,and trans-3-hexen-l-old in their BVOCs.Their items accounted for 12.24％,40.1％,2.44％,10.74％,24.32％,and 4.65％of the absolute unstable parts of P.orientalis,C.deodara,T.cuspidata,G.biloba,S.pekinensis and R.chinensis,respectively.The results of the review have significant hypothetical implications for the objective determination and scientific allocation of tree species for unban landscaping in Beijing.
