From the mycelia of Streptomyces mediocidicus four metabolites teleocidin B-1, B-2, B-3 and B-4 were isolated in crystalline states and their structures were determined by comparison with the known des-O-methylolivoretin B, and olivoretin D (teleocidin B of Hirata), and by studying the 13C-nuclear magnetic resonance (NMR) spectra.
