The transport of oleanolic acid synthesized from 14CO2 in the individual leaves of Calendula officinalis plants was investigated. It was proved that the rate and the direction of the transport depend on the stage of vegetation and the position of the leaf on the plant. The greatest transport rates of oleanolic acid were observed from the upper level leaves towards the inflorescence during the flowering period. The overblowing period was characterized by a slower migration of oleanolic acid from the leaf supplied with radioactive precursor. The migration was directed mainly to the root especially from the low level leaves. Using CH314COONa as precursor, it was established that the root is unable to synthesize oleanolic acid.
