| Abstract: | Aroma components in tea samples were analyzed using SPME coupled with GC-MS method,so as to exploit Maojian Tea resources.Results:92 kinds of aroma compounds were identified in tea samples Ⅰ,including 27 hydrocarbons,17 esters,12 aldehydes,11 olefins,10 ketones,7 alcohols,5 heterocyclic,3 benzene.89 kinds of aroma compounds were identified in tea samples Ⅱ,27 alkanes,13 esters,12 olefins,11 aldehydes,10 ketones,8 alcohols,6 heterocyclic,2 benzene.Tea sample Ⅰ and Ⅱ share a total of 78 kinds of aroma components,while unique ones are 14 and 11 kinds respectively.And the terpene indexes of tea sample Ⅰ and Ⅱ were respectively 0.950 8 and 0.785 3. |
