Abstract

Chrysomal and globerin complexes containing antibiotics from polyether and heptaene aromatic macrolide groups have been isolated from the mycelium of Streptomyces chrysomallus R-21 and Streptomyces globisporus L-242 strains, respectively. Physicochemical characteristics of these complexes have been investigated, including UV and NMR spectra, chromatographic parameters, etc. The fungicidal and antiviral activity of the studied complexes has been demonstrated on tomato plants. The obtained data allow us to consider the above-mentioned antibiotics to be original preparations.
