Abstract：
:In a survey of endophytic fungal biodiversity, an antimicrobial endophytic isolate zjwcf069 was obtained from twigs of Forsythia viridissima, Zhejiang Province, Southeast China. Zjwcf069 was then identified as Pezicula sp. through combination of morphological and phylogenetic analysis based on ITS-rDNA. Zjwcf069 here represented the first endophytic fungus in Pezicula isolated from host F. viridissima. From the fermentation broth, four compounds were obtained through silica gel column chromatography and Sephadex LH-20 under the guide of bioassay. Their structures were elucidated by spectroscopic analysis as mellein (1), ramulosin (2), butanedioic acid (3), and 4-methoxy-1(3H)-isobenzofuranone (4). Compound 4 here stood for the very first time as natural product from microbes. In vitro antifungal assay showed that compound 1 displayed growth inhibition against 9 plant pathogenic fungi, especially Botrytis cinerea and Fulvia fulva with EC50 values below 50 μg/mL. Endophytic fungi in medicinal plants were good resources for bioactive secondary metabolites.
