Abstract
HS-SPME/GC-MS was used for qualitative analysis of volatile compounds emitted from four types of fresh flowers: Dok Kaew, Dok Mok, Dok Phakakrong and Dok Tanyong. Volatile compounds in headspace were absorbed on PDMS/DVB fiber at room temperature for 15 minutes, the adsorbed compounds were thermally desorbed at 200°C in an injection port of GC and analysis by GC-MS. The results showed that the emitted volatile compounds in headspace have the differences in the profiles of compounds depend on type and the time after the flowers were picked. Total 75 compounds were detected and the important groups of compound were alkene, ester, aldehyde, ketone and alcohol with various quantity. The 53, 20, 35 and 2 compounds were found in headspace of Dok Kaew, Dok Mok, Dok Phakakrong and Dok Tanyong, respectively. The main compounds of Dok Kaew were benzaldehyde (53.6%), benzene acetaldehyde (13.0%) and β-cubebene (10.3%); in Dok Mok were benzaldehyde (28.6%) and benzene acetaldehyde (28.2%) in Dok Phakakrong were trans-β-ocimene (35.0%) and trans-caryophyllene (10.7%). High level of p-methylanisole (98.90%) was found in Dok Tanyong.
