Chelidonium majus L., celandine is part of the Papaveraceae family. In our country celandine is the component of hepatic teas, as well as frequently encountered as the formula of homeopathic drugs. Nowadays, it is recommended as a remedy in case of more than 150 diseases. In the period of 2014-2015 were collected samples of celandine from two populations, Oradea’s area and Ștei’s area and we making a comparison between the two populations. Our results show that the largest differences appear on the level of main stems. In case of the samples from Ștei the latex is present in very small quantities. These results are important, especially if we take into account the fact that it is a widely used medicinal plant. Key words: Chelidonium majus L., latex, hepatic teas INTRODUCTION Chelidonium majus L., celandine is one of Romanian spontaneous flora herbs that has been used since antiquity (Toma et al, 1998). Celandine is part of the Papaveraceae family, Rhoeadales order, subclass of Magnoliidae, class Dicotyledonatae. The Papaveraceae family, groups 300 of herbaceous annual, biannual or perennial species, widespread in spontaneous flora and other crops. It is characterized by pivotant root, branched stems and sessile- or short petiole leaves. Flowers are grouped in inflorescences. They consist of two lapsed sepals, four brightly colored petals, numerous stamens and carpels. The gynoecium consists of 6-12 intergrown carpels. The stigma has a varied form, lobed or star shaped. The androecium may be formed from numerous stamens or reduced to 6-4 stamens (Tamas, 1990, Toma et al, 1998, Oroian, 2004). The fruit is a globular capsule, oblong or silique, mono- or multisperma. The seeds have oily endosperm. It features the presence of laticifers in organs, secreting colored latex. From the chemical
