摘要: 从我国黑龙江漠河泥土中分离得到一株放线菌,通过16S rRNA基因测序分析,鉴定该菌株为Streptomyces nojiriensis SCSIO m34-1。采用摇瓶发酵方法对该菌株进行发酵,发酵产物经硅胶柱色谱及半制备高效液相分离得到7个化合物,利用HR-MS、1D和2D NMR波谱数据分析,鉴定其结构分别为izuminoside D(1)、izuminoside A(2)、solphenazine E(3)、solphenazine D(4)、solphenazine A(5)、6-羟基吩嗪-1-羧酸甲酯(methyl 6-hydroxyphenazine-1-carboxylate,6)和diastaphenazine(7),其中izuminoside D(1)是新化合物。抗真菌活性测试结果表明izuminoside D(1)在浓度为50 μg/mL时,对苹果腐烂病菌(Valsa mali)和小麦赤霉病菌(Gibberella sanbinetti)有微弱抑制活性。

Abstract: An actinomycetes strain SCSIO m34-1 was isolated from soil sample collected from Mohe,Heilongjiang province,China.The strain was identified as Streptomyces nojiriensis SCSIO m34-1 by analysis of its 16S rRNA gene sequence.The strain SCSIO m34-1 was fermented on rotary shakers.Seven compounds were purified from the organic extract using silica gel column chromatography and semi-preparative HPLC.Their structures were identified to be izuminoside D (1),izuminoside A (2),solphenazine E (3),solphenazine D (4),solphenazine A (5),methyl 6-hydroxy phenazine-1-carboxylate (6) and diastaphenazine (7) based on analyses of their HR-MS,1D and 2D NMR data.Izuminoside D (1) was found to be a new compound.Izuminoside D (1) showed weak antifungal activity against Valsa mali and Gibberella sanbinetti at the concentration of 50 μg/mL.

Key words: Streptomyces, secondary metabolite, alkloaid, phenazine
