The Dynamic Analysis Of Volatile Organic Compounds From Four Kinds Of Garden Plants

To explore the Garden Plant Volatile Organic Compounds and its dynamics characteristics, Osmanthus fragrans,Cinnamomum camphora,Phyllostachys viridis and Myrica rubra were selected as the research object, because they were frequencly used in greening. This study use dynamic headspace collection and thermal desorption / Gas chromatography / mass spectrometry (TDS / GC / MS) to analysis volatile organic constituents and its dynamics characteristics, The purpose of this study is to provide a theoretical basis for the scientific disposition and management of the Garden Plant .The main results are following:1. Osmanthus fragrans volatilize seven types of compounds which include aldehydes,alkenes,alcohols,ketones,esters,terpenoids,and acids. The esters accounted for the highest proportion of all compounds in day and May-September, followed by terpenoids. Esters were mainly consisted of (Z)-acetate -3-Hexen-1-ol, terpenoids were mainly consisted of dihydrocitr- onellol,hexa-hydro- farnesol in day and dihydrocitronellol,Z-ocimene in May-September. Osmanthus fragrans the most important release of esters to (Z)-acetate-3-Hexen-1-ol-based species.2. Cinnamomum camphora volatilize seven types of compounds which include aldehyde, alkenes, alcohols, ketones, esters, terpenoids, and acids. The terpenoids occupy an absolute superiority in day and May-September. In the 9:00-17:00 diurnal dynamics, terpenoids mainly consisted ofπ-ocimene,(E)-ocimene,(+)-2-camphor and dihydrocitronellol ; In May-September dynamics, its mainly consisted ofπ-ocimene,(Z)-ocimene,(E)-ocimene,(+) -2-camphor,1R-πPinene,camphene. Cinnamomum camphora is the most important release of terpenoids to ocimene and camphor-based species.3. Phyllostachys viridis volatilize seven types of compounds which include aldehydes,alkenes,alcohols,ketones,esters,terpenoids and acids. The Phyllostachys viridis mainly released terpenoids, followed by alcohols and aldehydes in day and May-September, terpenoids was mainly consisted of ocimene,dihydrocitronellol and alloaromadendrene; alcohols was mainly consisted of (Z)-3-hexene- 1-ol, aldehydes was mainly consisted of 2-methyl-4-Pentenal,decanal in day and nonanal,Decanal in May-September. Phyllostachys viridis is the most important release of terpenoids to ocimene and dihydrocitronellol-based species.4. Myrica rubra volatilize seven types of compounds which include aldehyde,alkenes,alcohols,ketones,esters,terpenoids and acids, In the 9:00-17:00 diurnal dynamics, Myrica rubra To explore the Garden Plant Volatile Organic Compounds and its dynamics characteristics, Osmanthus fragrans,Cinnamomum camphora,Phyllostachys viridis and Myrica rubra were selected as the research object, because they were frequencly used in greening. This study use dynamic headspace collection and thermal desorption / Gas chromatography / mass spectrometry (TDS / GC / MS) to analysis volatile organic constituents and its dynamics characteristics, The purpose of this study is to provide a theoretical basis for the scientific disposition and management of the Garden Plant .The main results are following:mainly released terpenoids which were mainly consisted ofπ-ocimene,caryophyllene,πcaryophyllene,dihydrocitronellol and (Z)--ocimene, followed by alcohols which were mainly consisted of 2-ethyl-1-hexanol; In May-September dynamics, its mainly released terpenoids which were mainly consisted of caryophyllene,πcaryophyllene,π-ocimene,(Z)-ocimene,(E)-ocimene,dihydrocitronellol and (+)-πSelinene. Myrica rubra is the most important release of terpenoids to caryophyllene and ocimene-based species.5. The types and concentration of VOCs from plants is mainly determined by their genetic characteristics. That the same species released the VOCs components and concentration was different when was at different times of day and in different months during the growing season, That four plants released VOCs components and concentration is different when belong to the different kinship.
