The invention discloses
saussurea involucrate nano particles and a preparation method and an application of the prepared
saussurea involucrate nano particles. The
saussurea involucrate nano particles in the invention is prepared by the following steps: taking
oil phase W emulsified particles as the carrier, taking the
aqueous solution of the effective component in the saussurea involucrate or the
alcohol solvent O as the internal aqueous phase carrying on the
oil phase W emulsified particles by stirring at a high speed to form W / O particles, and
coating a covering layer of emulsifier outside the W / O particles to form W / O / W multiple
emulsion nano particles. Measurements and tests prove that the grain
diameter of the saussurea involucrate nano particles in the invention is in a range of 60-800 nm, the average grain
diameter is 134.6nm; saussurea involucrate nano particles in the invention have a shape of quasisphere,
smooth surface, even size, no bond between particles, high
drug-
loading rate, good encapsulating rate and releasing effect and stable releasing rate, can be prepared into oral liquid, tablets, various capsules such as soft capsules, hard capsules and microcapsules, and can be prepared into parenteral solution,
lotion, embrocation, patch or electuary.
