An N-formyl cyclopeptide alkaloid from the bark of zizyphus sativa

Abstract

From the bark of Zizyphus sativa, previously undescribed cyclopeptide alkaloid, sativanine-F has been isolated. The structure was deduced by spectroscopic methods and chemical degradation. It is a 13-membered cyclopeptide alkaloid and provides the first example of such a naturally occurring N-formyl cyclopeptide alkaloid. © 1985.
