Effects Of Storage Conditions On Volatile Components Of Dingtan Zanthoxylum Bungeanum And Analysis Of Volatile Components Of Several Spices Produced In Guizhou

Objective: To investigate the effects of the storage condition on the volatile components of Zanthoxylum planispinum var.dintanensis Yu-Lin Tu.Methods: To analyze the volatile components of Zanthoxylum planispinum var.dintanensis Yu-Lin Tu and the change of those components under five storage conditions during the 12 months using gas chromatography-mass spectrometry coupled to solid phase microextraction.Results: Linalool(43.00%),sabinene(20.71%)and limonene(20.62%)were found to be the main components of the volatile components.The relative contain of the terpene in Zanthoxylum planispinum var.dintanensis Yu-Lin Tu decreased and the alcohol increased during 12 months of storage.Results showed the storage condition influenced remarkly the content of the volatile components and the time was an important factor.At the begin of 4 months of the storage,all the terpene and the olefin decreased beyond the alcohol,and the storage condition has little effect on the content of the volatile components.While after 4 months,the effects of the storage condition was remarkly.The good the airtight seal was,the less change the volatile components was.Similarly,the lower temperature was,the the less the volatile components changed and new component produced.Conclusion: Linalool(43.00%),sabinene(20.71%)and limonene(20.62%)were the main components of the volatile components of Zanthoxylum planispinum var.dintanensis Yu-Lin Tu.The good airtight seal and the low temperature were the effective condition to suppresse the change of those volatile components.Objective: To analysis the volatile components of Kaempferia galanga L.from Guizhou and compared with these of Guangxi.Methods: The volatile components of Kaempferia galanga L.from Guizhou were analyzed by using gas chromatography-mass spectrometry(GC-MS)coupled to solid phase microextraction(SPME).For the further analysis of the volatile components,the volatile components of Kaempferia galanga L.from Guangxi were also analysed by using SPME and FTIR spectrum.Results: The main components in Kaempferia galanga L.from Guizhou were estragole(6 1.5 3 %),5(1 H)-a z u l e n o n e,2,4,6,7,8,8 a-h e x a h y d r o-3,8-d i me t h y l-4-(1-methylethylidene)(15.54%)and seychellene(7.19%),three components of total content reached 84.26%.The total volatile components identified in Kaempferia galanga L.from Guizhou was 47,including 4 ethers,3 ketone,28 terpenoids,3 phenolic,2 alcohols,2 esters,2 aldehyde and 3 hydrocarbon.Among them,ethers,ketone and terpenoids had higher total percentage composition,reaching to 62.22%,15.83% and 13.68%,respectively.Conclusion: The volatile components of Kaempferia galanga L.from Guizhou were differented from those of Kaempferia galanga L.from Guangxi.Objective: To study the volatile component changes of Foeniculum vulgare mill.during storage.Methods: The volatile components of Foeniculum vulgare mill.during the 12 months storage were analyzed using gas chromatography-mass spectrometry(GC-MS)coupled to solid phase microextraction(SPME).Results: It was found that besides the main ingredient trans-anethole and estragole(the relative total content of them was 72.2%,85.49%,93.06%,95.89% and 90.13% in the origin,and 3,6,9 and 12 months storage sample,respectively),the content of others changed significantly.The relative content of anisealdehyde increased to 6.1% from 0.47% after the storage of 12 months.The relative content of linalool reduced to 0.28% from 9.72% at the time of 6 month storage.At the same storage time,the relative total content of the terpenoids reduced to 2.51% from 14.87%(main ingredient limonene reduced to 1.52% from 7.98%).Besides this,small amounts of esters(at the medium of storage),acids and alcohols(at the end of storage)were also detected in the storage.Conclusion: The volatile component of Foeniculu vulgare mill.during storage have obvious changes.
