The invention relates to the technical field of
medicine preparation, and discloses a heart-nourishing dropping
pill supercritical CO2 extraction and freeze-
drying process which comprises the following steps: S1, selecting heart-nourishing dropping
pill raw materials, cleaning, removing impurities and crushing; s2, extracting fructus choerospondiatis, fructus gardeniae,
flos carthami, radix angelicae sinensis and poria cocos through an
alcohol extraction process, extracting
semen myristicae,
ferula asafetida, agilawood, fructus tsaoko, cumin, radix aucklandiae,
calculus bovis factitius and saffron
crocus through a CO2 supercritical extraction process, and directly crushing to be used S3, uniformly stirring the extract and a dripping
pill matrix to prepare liquid
medicine; s4, preparing dropping pills from the liquid
medicine by adopting an
electrospinning-3D printing composite molding technology, and dropping the dropping pills into cooling liquid for cooling molding; and S5, atomizing the
coating material into nano-scale particles through a nano
spray dryer, uniformly
coating the surfaces of the dropping pills with the nano-scale particles, and bottling after the dropping pills are inspected to be qualified.
