【Abstract】 AIM:To study various properties of pre-nanoliposomes and to establish quality evaluation methods. METHOD:The form of the nanoliposome was observed with transmission electron microgram and the particles size,polydispersity,Zeta potential,entrapment efficiency,stability,blood vessel stimulating test and haemolyticus of the nanoliposome were evaluated . RESULT:The mean particle size of the nanoliposomes was 20.2 nm with polydispersity of 0.552. The Zeta potential was-74.5 mV. The entrapment efficiency was more than 70%.The liposomes prepared were stable and safe. CONCLUSION:The above-mentioned methods were suitable for the quality evaluation of breviscapine pre-nanoliposmes,and they can effectively express their properties.更多还原
