Structure (85) for a new alkaloid of Atalantia monophylla was based on the n.m.r. spectrum.An alkaloid obtained from Boenninghausenia albiflora, formerly regarded as 1,7-dihydroxy-N-methylacridone, has now been shown from the n.m.r. spectrum to... 

A preliminary study of the acridone alkaloids of the roots of Boenninghausenia albiflora resulted in the identification of 1-hydroxy-N-methylacridone (41 R = Me) now the Ruta alkaloid rutacridone (42) (c/. Vol. 8, p. 84) and noracrony-cine (43) have been isolated from this species. Of two new alkaloids obtained from B. albiflora, one was shown to be 1-hydroxyacridone (41 R = H) by methylation to (41 R = Me). The n.m.r. spectrum of the other new alkaloid suggested that it was a dihydroxy-N-methyl-acridone in which ring B contained a 1-hydroxy-group and three adjacent aromatic hydrogen atoms structure (44) was proposed.
