Four new nanaomycins ( 1 – 4 ), together with two known compounds, nanaomycin α A ( 5 ) and nanaomycin β A ( 6 ) were isolated from a fermentation broth of Streptomyces hebeiensis derived from lichen. The structures of the new nanaomycins 1 – 4 were established using comprehensive NMR spectroscopic data analysis as well as UV , IR , and MS data. The antimicrobial activities of 1 – 6 were evaluated against Gram ‐positive bacteria and fungus. Compounds 5 and 6 showed antimicrobial activities against the test microorganisms, while 1 – 4 were inactive at 100 μg/ml.
