✦ Synopsis

Metabolites from Microorganisms, 6‐Chlorogenistein and 6,3′‐Dichlorogenistein

A strain of Streptomyces griseus produced chlorinated metabolites in media containing soybean meal. Two of these metabolites were isolated together with a chlorine free compound which could be identified as the isoflavone genistein (I) by its spectral properties and by comparison with an authentic sample. By NMR. and mass spectroscopy the chlorinated compounds were shown to be 6‐chlorogenistein (II) and 6,3′‐dichlorogenistein (III).

The 7‐glucoside of genistein is a constituent of soybean meal; it is hydrolysed and chlorinated by Streptomyces griseus.
