| Abstract: | Fermentation broth of endophytic fungus Trichoderma taxi ZJUF0986 has high antifungal activity to the common 15 species of phytopathogenic fungi. Three bioactive metabolites I, II and III were obtained by extracted with petroleum ether, ethyl acetate and n-butanol and subsequent silica gel column chromatography and preparative HPLC. Among them, compound I, the main metabolite, has strong broad-spectrum antifungal activity, especially to Botrytis cinerea, Rhizoctonia solani and Sclerotinia sclerotiorum with IC50 1.06, 1.08 and 1.13 mg/L, respectively. |
