[Study on liposome preparation technique of Bupleurum chinense volatile oil for injection].
OBJECTIVE
To study the preparation technique of the liposome of Bupleurum chinense volatile oil.


METHODS
The composition, entrapment ratio of volatile oil, availability of freeze-drying and the changes of finger prints were studied.


RESULTS
Entrapment ratio reached 81.9%. After freeze-dried, the remaining ratio of the oil entrapped in the liposome reached 88.6%.


CONCLUSIONS
It is practicable to make B. chinense injection into freeze-dried liposome powder.
