Abstract:
The volatile components of 3 kinds of fresh leaves and 4 kinds of brewed Duyun Maojian tea were extracted by SPME,then analyzed by GC-MS referring to spectral library Nist 2005 and Wiley 275.Further more,the relative content of each component was determined by area normalization.The results showed that the volatile components of Duyun Maojian tea were mostly alcohols,aldehydes and hydrocarbons.There were different volatile components between fresh leaves and brewed tea,between growth stages and grades of tea.This manuscript will provide further development for characteristic aroma substance and application of Duyun Maojian tea.
