This report presents the results on the investigation of the effect of ricionoleic acid on the structures of the liquid crystal state of mixed phospholipid-cholesterol liposomes by means of the Small Angle X-ray Scattering (SAXS) and 31P Nuclear Magnetism Resomance(31P-NMR). The study shows that the ricinoleic acid helps to stabilize the structure of the mixed phospholipid-cholesterol liposomes and that the polyphase liposome with ricinoleic acid prepared from phosphoric buffer solution containing polyvinylpyrrolidone (PVP) is in the cubic-hexagonal phase.
