Abstract:

Gastrodia elata Bl. is a traditional Chinese herbal medicine with special pharmacological effects on headache and numbness. However, its wild sources are now in short supply because of over-excavation. A total of 14 endophytic fungi were isolated from Gastrodia elata Bl collected from Yinjing, in which 10 strains were identified, including Neonectria, Ascomycota, Fusarium, Oidiodendron and Dothiorella. All crude extracts showed some degrees of antioxidant activities by T-AOC method and DPPH methods, especially those from Oidiodendron GeR6 and Ascomycota sp. GeR2, which might be attributed due to their high phenolic contents. However, only Oidiodendron GeR6 contained gastrodin (39.2 μg/g) as the host plant in the crude extracts. In conclusion, the notable activities of GeR6 indicated its medical use as a natural antioxidant agent, as well as substitutable use for Gastrodia elata Bl. in the future.
