Objectives: Liposomes are reported as penetration enhancers for dermal and transdermal delivery. However, little is known about their percutaneous penetration and as to at which level they deliver encapsulated drugs. The penetration of multilamellar vesicles (MLVs) and small unilamellar vesicles (SUVs), in comparison to one of their lipid components, was investigated. Methods: Using the fluorescent lipid, Lissamine Rhodamine B-PE (R), as a constituent, MLV and SUV liposomes were prepared, tested, and R, MLV, or SUV were applied in vivo on the back of hairless mice. Absorption of each was evaluated at the levels of stratum corneum, living skin, and blood by fluorometry. Results: Penetration of the lipid R in stratum corneum in the nonliposomal form exceeded that in the liposomal form and only R penetrates the living skin in a statistically significant manner. No statistical significant absorption into blood was observed with either form. Conclusions: Liposomes size did not play an important role in penetration to stratum corneum. The lipid constituent in the nonliposomal form penetrated at higher rates into stratum corneum and living skin. Even though these liposomes entered stratum corneum, they were not significantly absorbed into viable skin or blood.

Specific volume of 1,2-dioleoyl-sn-glycero-3-phosphocholine and 1,2-dioleoyl-sn-glycero-3-phospho-l-serine mixtures in bilayers linearly depends on the molar fraction of the constituents, indicating an ideal volume mixing.

Encapsulation of bioactive compounds s been considered a promising tool for preserving these compounds. Several studies on dietary sources and health benefits of flavonoids, their chemical and stability properties, and encapsulation methods used for delivery of flavonoids were reviewed. Flavonoids comprise the main group of polyphenols widely found in fruits and vegetables responsible for numerous biological activities. They have a flavan nucleus with 15 carbon atoms organized in three rings and are categorized into six subgroups. The main dietary sources of flavonoids are fruits, vegetables, cereals, tea, and some herbs such as Viola odorata Linn. These compounds can prevent diseases such as cardiovascular, cancers, neurodegenerative, diabetes, and inflammatory bowel disease. Despite these beneficial biological activities, flavonoids are not stable against environmental conditions, have low water solubility and low bioavailability after oral administration, which restricts their application. Accordingly, encapsulation has been utilized in order to improve the stability and solubility of flavonoids. Various approaches such as spray drying, molecular complexes, liposomes, nanoparticles, emulsification, and multilamellar vesicles have been applied in the entrapment of flavonoids. Encapsulation can improve the stability of flavonoids as well as solubility, controlled release, and bioavailability.
