The invention belongs to the field of preparations, and particularly relates to radix salviae miltiorrhizae extract nanocrystalline self-stabilization
Pickering emulsion and preparation method thereof. According to the radix salviae miltiorrhizae extract nanocrystalline self-stabilization
Pickering emulsion disclosed by the invention, a radix salviae miltiorrhizae extract of which the salvianolicacid B content is 60-100mg / g, the tanshinol content is 3-10mg / g, the
rosmarinic acid content is 3-10mg / g, the tanshinone II A content is 5-20mg / g, the cryptotanshinone content is 2-10mg / g and the
tanshinone I content is 3-10mg / g is used as a
raw material medicine, and the radix salviae miltiorrhizae extract, an
oil phase and an aqueous phase are prepared into oil-in-water
Pickering emulsion. The nanocrystalline self-stabilization Pickering
emulsion having stability properties is prepared through using the radix salviae miltiorrhizae extract containing water-soluble
medicine effect ingredientsand insoluble
medicine effect ingredients of radix salviae miltiorrhizae at the same time as the
raw material medicine, wherein the water-soluble ingredients of
salvianolic acid B and the like are distributed in the aqueous phase, and insoluble ingredients of tanshinone and the like are partially distributed in the
oil phase and are partially adsorbed on an
emulsion droplet interface, so that theemulsion is stabilized.
