A checklist is presented of floral scent compounds retrieved by head-space techniques and separated and identified mainly by gas chromatography and mass spectrometry. The checklist is based on reports presented in 118 original articles between the years 1966 and 1992. The emphasis in our discussion is on comparison of identified chemical substances as a basis for studies of pollination attractants. Isolation techniques, systematic implications of floral scents and structure-activity relationships are briefly discussed. In all over 700 identified compounds are listed from 441 taxa in 174 genera in 60 families of plants. They mainly represent fatty acid derivatives, benzenoids, phenylpropanoids, isoprenoids, nitrogen- and sulphur-containing compounds. |
