灰藤黄链霉菌P510中两个活性吩嗪类物质的分离及结构鉴定（英文）

摘要

Phenazine antibiotics phenazine-1-carboxylic acid(PCA)and 1-hydroxyphenazine(1-OH-PHZ)were purified from culture broth and mycelia of Streptomyces griseoluteus P510.Both PCA and 1-OH-PHZ exhibit strong antifungal activity against six plant pathogens,especially Fusarium oxysporium,with minimal inhibition concentrations less than 1 and 2μg·ml-1for PCA and 1-OH-PHZ,respectively.The presence of PCA and 1-OH-PHZ indicates that S.griseoluteus P510 can be used as a potential source of pesticides.
