Embodiment 1
[0075] Preparation of the active ingredient of the present invention:
[0076] Salvia miltiorrhiza extract: obtained according to the preparation method of Chinese patent application (application number 02117923.9). The specific extraction method is as follows: 5 kg of Salvia miltiorrhiza are crushed into coarse powder, and deionized water is added to heat and extract 3 times in a slightly boiling state at 100°C. The first time is 5.5 times the water, heating for 1 hour; the second and third times, each adding 3 times the amount of water to heat for 0.5 hours. After the extract was adjusted to pH 2 with 10% hydrochloric acid, it was filtered, and the filtrate was applied to a polyamide column (the amount of dry resin is 2 / 3 of the crude drug amount). Wash with 5 times the amount of deionized water, and continue to elute with 0.1% sodium bicarbonate aqueous solution, the amount is 5 times the column volume. Collect the eluent, adjust the pH to 2 with 10% hydrochloric acid, and then...

[0083] Preparation of the active ingredient of the present invention: take 1000 g of Salvia miltiorrhiza extract of Example 1, 2000 g of Panax notoginseng extract of Example 1, and 100 g of Dalbergia odorifera oil of Example 1 and mix them uniformly to prepare the active ingredient of the present invention;
[0084] Preparation of masterbatch: take a mixture of micronized silica gel and chitosan with a weight ratio of 1:1 and pass it through a 200-mesh sieve, of which 65% is used as the bottom material into the spray pot on the side of the fluidized bed, and PVP K30 is added with water, extract, and preparation Viscosity-forming agent-sprayed in as a slurry, and screened out small particles with a particle size of 120-180μ as the mother core, then put the mother core into the pot, continue to spray the starch slurry, and at the same time, the remaining 35% from the dusting gun The fine powder of silica gel and chitosan are sprinkled in to increase the particle size of the core, an...
