Abstract
Objective:To prepare baicalin flexible nano-liposomes.Method:By film dispersion method to prepare flexible nano liposome suspension to the content of baicalin in encapsulation efficiency as the technology of the evaluation index
particle size
particle size dispersion coefficient
Zeta potential and entrapment efficiency of the indexes
the best prescription by orthogonal test and the preparation conditions
and studied its physical and chemical properties.Result:The best prescription and conditions for the preparation of lecithin and sodium cholate mass ratio of 6 :1
lecithin and baicalin is a 10 :1 ratio
ultrasonic probe time is 15min.The encapsulation efficiency was 60.11%
from the flexible nano-liposomes are spherical solid particles
average particle size of 175 nm
the average Zeta potential was-78.9 mV.Conclusion:Baicalin flexible nano-liposomes formulation and preparation process are basically feasible.
