Abstract

New paralytic alkaloids, asperparallines A (1), B (2) and C (3), were isolated from okara (the insoluble residue of whole soybean) that had been fermented with Aspergillus japonicus JV-23. Their structures were elucidated by spectroscopic methods and X-ray crystallography. These asperparalines showed paralytic activity against silkworms.
