Method for the separation and purification of antibiotic macrolides

摘要

This case relates to a novel process which aids in the isolation and purification of novel compounds which are produced by the microorganism, Streptomyces avermitilis. The process described utilizes a non-aqueous extraction system for purifying crude extracts of the novel compounds. The compounds which are isolated and purified are described generically as C-076 and have significant parasiticidal activity.
