Full-component extract of and its effect on epidermal regeneration.

As a well-known aromatic herb rich in various bioactive molecules, the extract of is widely used in cosmetics. However, the extraction process for is far from perfect. Moreover, the water- and oil-soluble components are too complex to be compatible with each other. Thus, the traditional water- or oil-based extracts of encompass only water- or oil-soluble components, respectively. The effective components being incomplete results in significantly reduced effects. Therefore, obtaining a full-component extract of is imperative to ensure its full functionality. Herein, a full-component extract of based on miscibility between polyol and oil was developed by extracting water-soluble active substances with a ternary solvent, followed by mixing them with oil extracts of . In ternary solvents, most water-soluble compounds of can be extracted by ethanol. During evaporation, the water-soluble components are transferred and dissolved in hexanediol from the solvent. Thus, by blending hexanediol with caprylic/capric triglyceride (GTCC), we successfully created a potent full-component extract of . Through the study of the barrier-weakening 3D full-skin model, it was found that the full-component extract of , rich in chlorogenic acid, could significantly promote the epidermal regeneration of UV-induced skin damage compared to the oil-based extract components.
