초록
이전 연구에서 저자들은 사자발쑥 추출물의 항산화, 항노화 및 항균활성에 대한 결과를 보고한 바 있다. 본 연구에서는 사자발쑥 추출물의 피부 전달시스템으로 에토좀을 제조하고 입자크기, 포집효율 및 피부 투과를 평가하였다. 0.06% 사자발쑥 추출물의 에틸아세테이트 분획을 담지한 에토좀은 3주 동안 보다 더 안정하였고 일정한 입자크기를 유지하였다. 0.06% 에틸아세테이트 분획을 함유한 에토좀의 입자 크기는 287.05 ± 0.25 nm, 포집효율은 51.96 ± 0.01%였다. 피부 투과 실험 결과, 에토좀 제형은 일반 리포좀이나 20% 에탄올 용액에서 보다 큰 피부 투과능을 보여주었다.
In our previous studies, the antioxidant, anti-aging, and antibacterial activities of Artemisia princeps Pampnini (A. princeps Pamp.) extract were reported. In this study, ethosome formulations for the enhanced transdermal delivery of A. princeps Pamp. extract were prepared. The particle size, loading efficiency and skin permeation of them were evaluated. The ethosome loaded with 0.06% ethyl acetate fraction of A. princeps Pamp. extract was more stable and maintained the constant particle size for 3 weeks after being prepared. The particle size of ethosome containing 0.06% ethyl acetate fraction was 287.05 ± 0.25 nm and the loading efficiency was 51.96 ± 0.01%. The ethosome formulation exhibited the greater enhancement of skin permeation than of general liposome and 20% ethanol solution in skin permeability experiments.
