A new antibiotic, designated mumiamicin, was isolated from the cultured broth of the rare actinomycete strain, Mumia sp. YSP-2-79, by Diaion HP-20, silica gel and ODS column chromatography, followed by HPLC purification. The chemical structure of mumiamicin was elucidated as a new furan fatty acid by nuclear magnetic resonance and mass spectrometry. Mumiamicin showed antimicrobial activity and antioxidative activity.
