Polymer Chemistry in Sustained-Release Herbal Composites: Designing a Stable Euphorbia tithymaloides Topical System with Phospholipid and Polymer Matrices
Abstract: Polymer chemistry enables the stabilization and sustained release of herbal actives, critical for topical therapeutic applications. This study explores a novel process for preparing a stable, sustained-release topical composition of Euphorbia tithymaloides, leveraging polymer-based systems. Ethanolic extract (50 mg) of the plant, rich in unstable sugar moieties (e.g., D-ribose) and sterols (e.g., stigmasterol), is encapsulated within a phospholipid matrix of phosphatidylcholine (50–100 mg) and cholesterol (50–100 mg). This lipid-polymer complex, …

The Role of Cholesterol in Biological Membranes
Abstract: Cholesterol plays the role of a regulator that ensures the correct packaging of the lipid part of the membrane, which is necessary for its normal operation, by influencing on the mobility of the fatty acid tails of membrane lipids: if the membrane is too rigid and there is a danger of "freezing" of fatty acid chains, cholesterol causes it to liquefy, since the chains in its presence become more mobile; …

Formulation and Evaluation of Aqueous Azadirachta indica Phytosome
Abstract: A phytosome is a complex created through the union of a natural compound, typically a plant extract, with a phospholipid. Phospholipids play a crucial role in cell membranes, possessing a structure comprising a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tails. This distinctive structure enables phospholipids to construct lipid bilayers, fundamental elements of cell membranes. Phytosome increases the bioavailability, and absorption of active chemical constituents in the extract with the help …

Liposomes Innovative Role as a Drug Delivery System: A Detailed Analysis
Abstract: The first nanomedicine to be approved for use in clinical settings was liposomes. These are the spherical vesicles with a bilayer of phospholipids enclosing a middle empty aqueous region. Because of their extraordinary potential to stop medication deterioration and lessen unwanted effects, liposomes are being utilized more and more for targeted drug distribution. For targeted drug delivery, the pharmaceuticals can be integrated into the liposomes' aqueous space or phospholipid bilayer. …
