Chemical Constituents from Stem Bark and Roots of Clausena anisata
Songue, Jules Lobe; Kouam; Dongo, Etienne; Mpondo, Theophile Ngando; White, Robert L.
Phytochemical investigations on the stem bark and roots of the tropical shrub Clausena anisata
led to the isolation and characterization three carbazole alkaloids: girinimbine, murrayamine-A and
ekeberginine; two peptide derivatives: aurantiamide acetate and
N-benzoyl-L-phenylalaninyl-N-benzoyl-L-phenylalaninate; and a mixture of two phytosterols:
sitosterol and stigmasterol. The structures of these compounds were established by nuclear magnetic
resonance (H-1-NMR, C-13-NMR, COSY, HSQC, HMQC, HMBC and NOESY) spectroscopy and electrospray
ionization mass spectrometry (MS).
