Acridone Alkaloids and Coumarins from the Stem Bark of Citropsis articulata (Rutaceae)

Meva'a LM, Songue JL, Wansi J, et al. Acridone Alkaloids and Coumarins from the Stem Bark of Citropsis articulata (Rutaceae). Zeitschrift für Naturforschung B. 2010;65(4):525-527.A new acridone alkaloid, citropsine A (1), and thirteen known compounds (2-14) were isolated from the MeOH extract of the stem bark of Citropsis articulata. Structures of all compounds were determined by detailed analyses of their ID and 2D NMR spectra, mass spectrometric data and by comparison with previously known analogs
