Abstract: Unique flavor and elements components of wild Tremellodon gelatinosum in Yunnan were investigate by using GC-MS, amino acid analyzer and ICP-MS analysis. The results showed that under room temperature there are 42 volatile aroma matters(mainly alkyl alcohols, alkenes and heterocyclic compounds), 17 non-volatile active matters (amino acid), 10 microelements and 9 rare-earth elements in wild T.gelatinosum. This indicates that T.gelatinosum possesses high nutritional value and medicinal value.

Key words: wild Tremellodon gelatinosum, aroma matter, amino acid, microelements, rare-earth elements
