Objective: To screen and identify endophytic fungi producing podophyllotoxin compounds from Sinopodophyllum hexandrum stems
and to provide the reference for protection of S. hexandrum plant resources and discovery of new natural active strains. Method: The endophytic fungi from S. hexandrum stems was isolated by tissue block method
the metabolites of podophyllotoxin compounds were detected by TLC and HPLC
combination of morphology and molecular biology was adopted to identify endophytic fungi producing podophyllotoxin compounds. Result: Nine strains of endophytic fungi were isolated
which J-1
J-2 and J-3 strains in the fermentation broth contained podophyllotoxin compounds
they were identified as Chaetomium globosum strain MF564
C. sp. 4RF3 and Pseudallescheria sp. T55. Conclusion: Three strains of endophytic fungi producing podophyllotoxin compounds are isolated from S. hexandrum stems
