Abstract
The structure of breynogenin (C22H26O9S), an aglycone of breynin A, was established as III on the basis of chemical and spectral investigations. The structure of isobreynogenin (C22H26O9S), a secondary degradation product from breynin A, was determined as IV. Partial structure for breynin A has been presumed.
