Abstract:Twenty-four isolates of endophytic fungi were isolated from the rhizomes of Polygonum cuspidaturn Sieb. et Zucc.. The antibiotic activity of these endophytic fungi was tested through antirnicrobial experiments in the exterior body. The result showed that three isolates of them were able to produce antibiotic active substances. The three antirnicrobial fungi were identified as Aspergillus, Penicillium and Mycelia sterillia respectively.
Keywords:Polygonum cuspidatum  endophytic fungi  antibiotic active substance
