Stoffwechselprodukte von Mikroorganismen 227. Mitteilung. Isolierung und Strukturaufklärung von Rutamycin B

Isolation and Structure of Rutamycin B Botrycidin was found to be identical with rutamycin. From the cultures of the actinomycete producing botrycidin and the venturicidines. A and B, a fourth antifungal antibiotic, rutamycin B, was isolated. Through a series of degradation products its structure could be correlated to that of rutamycin, which had been determined before by an X‐ray structural analysis. Rutamycin B has been identified as 12‐deocy‐rutamycin.
