新乌头碱脂质体制备工艺的研究
Preparation technology for liposome of new aconitine
摘要
Abstract
Objective To study and optimize the preparation technology and prescription of liposome of new aconitine aiming at reducing toxicity, improving efficiency, and being suitable for industrial production with higher stability. Methods The liposome of new aconitine was prepared by using freeze-drying method, and its prescription and preparation technology were optimized by using single-factor experiment. The encapsulation efficiency(EE) and particle size were taken as review indexes,the EE of liposome of new aconitine was determined by using centrifugation and centrifugation conditions were investigated. Results The best prescription included that ratio of lecithin to cholesterol was 3:1,ratio of drug to lipid was 1:20,ratio of sugar to lipid was 5:1,and ratio of organic solvent to water was 1:3. The centrifugal conditions for determining EE were 2 000 r/min and centrifugation time was for 5 min. Under these conditions,the free drug could be separated from the drug-containing liposome. Conclusion The liposome of new aconitine obtained by this technology has reasonable prescription, feasible process and higher EE and stability.关键词
