title: An N-formyl cyclopeptide alkaloid from Zizyphus nummularia bark.
abstract: A 13-membered N-formylcyclopeptide alkaloid, nummularine-T, has been isolated from the bark of Zizyphus nummularia and its structure established by spectroscopic and chemical methods. It provides the fourth example of a naturally occurring N-formyl cyclopeptide alkaloid.
