The qualitative and quantitative changes in the composition of the combined bases in Reseda luteola during the vegetation periods have been studied. From the epigeal part of the plant we have isolated cinnamamide and two new alkaloids: lutine and lutinine. A study of the spectral characteristics and the mechanism of fragmentation has shown that lutine has the structure of 2-anilino-1,4-naphthoquinone and lutidine that of 4-anilino-2-phenylamino-1,2-dihydronaphthalen-1-one. © 1978 Plenum Publishing Corporation.
