Abstract: YY26,YG42 and YG71 were three endophytic fungi strains isolated from Cinnamomum longepaniculatum. With C.longepaniculatum oil as inductor,GC-FID and GC-MS were used to analyze the accumulation of 1,8-cineole, terpinen-4-ol, a-terpineol and r-Terpinene in YY26,YG42,and YG71 strains under different media conditions. The experimental results indicated that in PDB medium C.longepaniculatum oil can promote accumulation of 1,8-cineole inYY26,YG42 strains and the content of 1,8-cineole increased by 1.41 and 1.30 times respectively,while 1,8-cineole were repressed in strains YG71 in PDB medium. C.longepaniculatum oil had no obvious promotion effect on the 4 compounds in czapek′s medium.This study provided scientific basis for the large-scale production of natural metabolites.

Key words: Cinnamomum longepaniculatum oil, endophytic fungi, GC-FID, GC-MS, 1,8-cineole
