title: Two new quinoline and tris(4-hydroxycinnamoyl)spermine derivatives from Microdesmis keayana roots.
abstract: Purification of a Microdesmis keayana hydromethanolic root extract led to the isolation of two new natural compounds, xanthoquininamide (6-hydroxyquinoline-4-carboxamide) and tris(4-hydroxycinnamoyl)spermine (N(5)-(p-coumaroyl)-N(1),N(14)-diferuloylspermine) which was named keayanine. Their structures were determined using spectroscopic analyses (ESI-MS, 1D- and 2D-NMR).
