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
