FUNCTIONAL CONNECTION BETWEEN INTRACELLULAR AND EXTRACELLULAR SECRETION IN SPECIES OF EUPHORBIA GENUS

In species of the Euphorbia genus the intracellular latex-secretion an d the extracellular nectar-secretion are anatomically connected. The f unctional connection of the secretional systems was proved to be proba ble by TLC and GC-MSD. The chemical composition of Euphorbia latex and honey was examined with these analytical methods. In our research, th e comparative chemical analysis of the latex and the honey of two Euph orbia species (Euphorbia cyparissias L., Euphorbia seguieriana Necker. ) was discharged. These species are unusually good melliferous plants in Hungary. Four chemical components that can be found both in the lat ex and in the honey were detected with ultraviolet light (254 nm), and three general alkaloid reagents (Dragendorff, Meyer and 1% Ce(SO4)(2) in 2n H2SO4) were detected by TLC. By means of mass spectrum generate d by GC-MSD, the following compounds of Euphorbia honey were identifie d: butyl-2-methylpropyl phtalat, hexadecane acid, diheptyl phtalat, bi s (2-ethyl-hexyl) phtalat, benzenedicarboxylic acid decyl-hexyl ester, benzenedicarboxylic acid isodecyl-octyl ester. The first compounds ca n also be found in the latex of both examined Euphorbia species. This partial correspondence in the composition of the latex and the honey l ed to results that suggest a further, functional connection between th e two, anatomically connected secretional systems.
