Zizyphus amphibia contains small amounts of nuciferine in addition to the amphibines (47). Discaria crenata (Clos.) Regal yielded armepavine, A-methylcoclaurine, and a peptide alkaloid which may be identical with scutianine-B (46). [Pg.203]

Rhamnaceous plant Discaria pubescens, differs from melonovine A only in its melting point and its optical rotation, and is thus considered to be diastereo-isomeric with respect to the amino-acid chain.19... [Pg.295]

A number of new 14-membered-ring alkaloids incorporating the p-hydroxy-styrylamine and j8-hydroxyphenylalanine structural features have been isolated and structurally elucidated, mainly by application of high-resolution mass spectrometry. Cre natine A (55) has been obtained from Discaria crenata while alkaloid A, (feretine) (56) and alkaloid A2 (57) have been isolated from Feretia apondanthera. In addition to four known alkaloids, the root bark of Zizyphus nummularia has yielded nummularine-D (58) and nummularine-E (59). ... [Pg.306]

From Discaria febrifuga (Rhamnaceae), four new cyclopeptide alkaloids, discarines F (72) (55), G (73) (56), H (74) (57), and E (71) (58), have been isolated. These cyclopeptide alkaloids are 14-membered cyclic peptides. A new 14-membered ring peptide alkaloid discarine I (75) and its known relative discarine B (68) have been isolated from D. febrifiiga (59). Further studies on the peptide alkaloids produced by D. febrifuga have resulted in the characterization of the tryptophan-containing alkaloid discarine K (76) (60). H- and C-chemical shift assignments of the cyclopeptide alkaloid discarine B (68) were completed based on 2D-NMR experiments such as H- H and COSY spectra (61). From the methanol extract of the...
