摘要：目的研究不同透皮促渗剂对淫羊藿苷体外经皮渗透的影响,筛选出最佳促渗剂。方法选用氮酮、薄荷脑、冰片为促渗剂,采用Franz扩散池法,考察单一促渗剂及三元复合促渗剂对淫羊藿苷体外透皮吸收的影响,采用正交设计,选用L_(9)(3^(4))正交试验表,以淫羊藿苷累积渗透量为指标,优选出三元复合促渗剂。以雄性小鼠离体皮肤作为渗透屏障,含20%乙醇的PBS溶液为接收液,HPLC法测定淫羊藿苷的含量。结果促渗剂以1%氮酮、2%冰片及2%薄荷脑为组合时促渗效果最佳。结论三元复合促渗剂可显著提高淫羊藿苷的经皮渗透性,为后续将淫羊藿及以淫羊藿为主要的方剂制备成经皮制剂提供促渗物质。
Objective To study the effects of different transdermal enhancers on the percutaneous penetration of icariin in vitro, and select the best enhancer. Methods Azone, menthol and borneol were selected as penetration enhancers. Franz diffusion cell method was used to investigate the effects of single penetration enhancer and ternary composite penetration enhancer on the percutaneous absorption of icariin in vitro. Orthogonal design was adopted, L_(9)(3^(4)) orthogonal test table was selected, and the cumulative penetration amount of icariin was taken as the index to screen out the best ternary penetration enhancer. The content of icariin was determined by HPLC with the isolated skin of male mice as permeation barrier and PBS solution containing 20% ethanol as receiving solution. Results The combination of 1% azone, 2% borneol and 2% menthol had the best permeation promoting effect. Conclusion Ternary penetration enhancers could significantly improve the transdermal permeability of icariin, and provide penetration enhancers for the subsequent preparation of epimedium and epimedium-containing prescriptions into transdermal preparations.
