Abstract

Streptazolin, a lipophilic neutral compound giving a yellow colour reaction with Ehrlich reagent, was isolated from cultures of Streptomyces viridochromogenes, strain Tü‐1678. On the basis of a “chemical screening”. Its structure, 1, was determined by spectroscopic investigations and chemical degradations. Dihydrostreptazolin 3 exhibits limited antimicrobial activities. Pharmacological investigations are in progress.
