Droseraceae plants are owned by the family of carnivorous plants, which in an unusual way adapt to environments poor in nutrients. Droseraceae obtain essential nutrients catching insects and other small invertebrantes. Plumbagin, chloroplumbagin, ramentaceon and droseron are naphthoquinones, which could be found in leaves and shoots of plants from Droseraceae family. In the literature there are a lot of information about the pharmacological properities of these secondary metabolites.

The purpose of this research was to develop optimal conditions for separation of naphthoquinones contained in extracts of insectivorous plants of the species Dionaea muscipula Ellis, Drosera aliciae Raym.-Hamet, Drosera capensis L. and Drosera binata Labill.

The experimental studies have been divided into two stages, the first included study using thin layer chromatography (TLC) and the second using high performance liquid chromatography (HPLC) technique. Both the studies by thin layer chromatography and high performance liquid chromatography was performed in normal and reversed phase system. Optimal conditions of naphthoquinones separation using TLC and HPLC in normal and reversed phase system will be presented.
