title: Ethosomes and Transfersomes for Topical Delivery of Ginsenoside Rhl from Red Ginseng: Characterization and In Vitro Evaluation.
abstract: Red ginseng (the steamed root of Panax ginseng C. A. Mayer), which contains ginsenosides as its main constituents, is frequently used to treat tumor, inflammation, diabetes, stress and acquired immunodeficiency syndrome in Asian countries. Ginsenoside Rhl, a bacterial metabolite of ginsenoside Rgl, is a protopanaxatriol type of ginsenosides. Liposomes do not deeply penetrate the skin and remain confined to the stratum corneum.Thus, new vesicular colloidal carriers such as ethosomes and transfersomes have been developed as an enhanced type of liposomes, recently. The aim of this study was to improve the topical delivery of ginsenoside Rhl isolated from red ginseng employing new vesicular system of ethosomes and transfersomes compared to conventional liposome. Characterization of ginsenoside Rhl-loaded vesicles were prepared and evaluated for particle size, zeta potential, entrapment efficiency (% EE), and transmission electron microscopy (TEM) studies. In addition, skin permeation profile was obtained using frantz diffusion cells and rat dorsal skin treated with ethosome and transfersome compared with conventional iposome. The size of vesicles range from 108.5 to 322.9 nm, and negatively charged from -20.95 to -31.37 mV. The % EE of ginsenoside Rh1 was obtained between 45.0 to 65.0%. Transfersomes provided a significantly higher skin permeation of ginsenoside Rhl compared to ethosome and conventional liposome. Therefore, based on the current study, ginsenoside Rhl-loaded transfersomes can act as a topical therapeutic effects potential.
