Abstract

A novel antibiotic α, β-unsaturated sesquiterpene ketone, albaflavenone with a zizaene skeleton was isolated from a morphologically novel, highly odorous Streptomyces species which was identified with the species group S. albidoflavus, cluster 1. The new compound, partly responsible for the odour, was assigned the structure of 2R', 6, 7, 7-tetramethyl-1S', 8R'-tricyclo-[6.2.1.0^{1, 5}]undec-5-en-4-one based on spectroscopic studies including 2D NMR (COSY, HETCOR, ROESY, NOE-difference) experiments.
