Objective. Aim of this work was to create a stable liposomal dosage form of native hydrophobic antitumor compound from the group of indolocarbazoles-LHS-1208. Materials and methods. Quantitative analysis of the drug content in liposomes was determined by spectrophotometry with a standard sample at λ = 320 ± 2 nm. The encapsulation was investigated as the ratio of LHS-1208 concentration in the liposomal dispersion after extrusion through nylon membrane filters 0.22 µm "Pall" to concentration LHS-1208 in liposomal dispersions before filtration. pH of the liposome was determitaned by the method of potentiometry. The size of liposomes was evaluated by nanosizer. Cytotoxic activity was studied by MTT-test.
