摘要: 对青海干旱生境土壤链霉菌Streptomyces pactum KIB-HL8液体发酵,应用硅胶柱色谱和高效液相色谱等方法进行分离和纯化,得到5个化合物,并用MS、NMR等方法对其结构进行解析,分别鉴定为N-乙酰酪胺(1)、N-乙酰色胺(2)、吡咯-2-甲酰胺(3)、Inthomycin C(4)和Inthomycin B(5)。对其抗真菌、细菌活性进行筛选,发现化合物4对金黄色葡萄球菌有抑制活性,化合物1和2对番茄灰霉病菌有抑制活性,化合物3对番茄早疫病菌有较强的抑制活性。

Abstract: Five compounds, N-acetyramine (1), N-acetyltryptamine (2),pyrrole-2-carboxamide (3),inthomycin C (4) and inthomycin B (5),were isolated from the fermentation broth of Streptomyces pactum KIB-HL8,and their structures were elucidated by analysis of NMR and MS data.In addition,compound 4 moderately inhibited growth of Staphylococcus aureus. Compounds 1 and 2 showed significant antifungal activity against Botrytis cinerea. Compound 3 displayed inhibitory activity against Alternaria solani.

Key words: Streptomyces, secondary metabolites, isolation and identification, antibacterial activity, antifungal activity
