Flavonoids are phenolic compounds widely present in plants as secondary metabolites. They exhibit a wide range of biological effects arising mainly from their ability to modulate several enzymes or nuclear receptors, alter gene expression, chelate bivalent metals. Quercetin is the most abundant of the flavonoid molecules in plants and it is the most studied one. Quercetin effect on Polycelis felina (Daly.), which is convenient test organism in such studies, has not been analyzed in laboratory yet. In these tests it is determined that implemented concentration of quercetin cause behevioral changes of treated animals, morphological changes in depigmentation of certain body parts and histopathological-cytological structure of treated planarian. The most exceptional changes are noticed on totipotent cells of neoblasts and reticular cells. Determined changes were most intensive on the third day after treatment, and above mentioned cells were represented in higher number compared to control group of animals.
