| Abstract: | Differences were shown in histological localization of psoralensof Angelica archangelica, Daucus carota, Sium suave and Psoraleabituminosa. All the fruits examined contained furanocoumarinson the surface. Fruit tissues contained very low (Sium), medium(Angelica) or high (Psoralea) concentrations of these compounds.Seed covers showed low autofluorescence in Angelica but highin Sium . Not all the glands in fruit or seed tissue exhibitedautofluorescence. Embryos always contained furanocoumarins ontheir surface and in their tissues in varying proportions. Autofluorescencecan be homogeneously distributed among all cells of the embryo(Sium) or can be concentrated in certain cells (Psoralea).Copyright1993, 1999 Academic Press Autofluorescence, furanocoumarins |
