|Title:||Peptide Alkaloids Of Scutia Buxifolia|
Van Fossen Bravo R.
de A.M. Reis F.
|Abstract:||From the bark extract of S. buxifolia, the known alkaloids scutianines B, C, D and E, and the new one, scutianine H, have been isolated. The structure of scutianine H, based mainly on its MS fragmentation and on the MIKES (mass-analysed ion kinetic energy spectrum) of the base ion peak, is suggested. From the 13C NMR spectral analysis of the diastereoisomeric scutianines D and E, information for the assignment of the stereochemistry of the β-hydroxyleucine unit in related alkaloids was also obtained. © 1979.|
