摘要:

对来源于药用植物三七(Panax notoginseng)根际土壤的链霉菌Streptomyces sp.KIB-QJ27进行次级代谢产物研究,利用MCI柱色谱、葡聚糖凝胶柱色谱和半制备HPLC等分离手段对其发酵产物进行分离纯化,得到7个化合物。采用MS和NMR等现代波谱技术并结合文献报道对其结构进行解析,分别鉴定为nortetillapyronpyrone(1)、tetillapyrone(2)、cyclo(L)-4-OH-Pro-(L)-Phe(3)、N1-acetyl-N5,N10-di-p-(EE)- coumaroylspermidine(4)、1H-pyrrole-2-carbothioic acid(5)、futalosine(6)和1,3,6-trihydroxy-8-n- propylanthraquinone(7)。抗菌活性筛选发现化合物7具有广谱抗菌活性,对小麦赤霉病菌、玉米弯孢病菌、棉花枯萎病菌、斜卧青霉、金黄色葡萄球菌、枯草芽孢杆菌、大肠杆菌均有抗性。

Abstract:

Seven compounds were isolated from a rhizospheric soil-derived Streptomyces species of Panax notoginseng by various chromatography methods including MCI,Sephadex LH-20 column chromatography,and semipreparative HPLC.Their structures were elucidated as nortetillapyronpyrone(1),tetillapyrone(2),cyclo(L)-4-OH-Pro-(L)-Phe(3),N1-acetyl-N5,N10-di-p-(EE)- coumaroylspermidine(4),1H-pyrrole-2-carbothioic acid(5),futalosine(6)and 1,3,6-trihydroxy-8-n- propylanthraquinone(7), respectively,based on the analyses of their MS and NMR data.Compound 7 showed a wide range of inhibitory activities against Gibberella zeae, Fusarium oxysporum Schl. f.sp.vasinfectum, Penicillum decumberns, Curvularia lunata (Walk) Boed,Staphyloccocus aureus, Bacillus subtilis and Escherichia coli.
