[0018] 4. The preparation method of compound danshensu injection
[0019] (1) In parts by weight, take 1 part of paeonol and dissolve it with 20 parts of absolute ethanol; take another 6 parts of hydroxypropyl-β-cyclodextrin, add water for injection in a water bath at 50°C to make a saturated solution; Slowly add paeonol absolute ethanol solution dropwise to hydroxypropyl-β-cyclodextrin at a rate of 3 drops / min, keep stirring at the temperature of the water bath until the absolute ethanol evaporates, sonicate for 1 hour, and refrigerate at 4°C Overnight, filter, and dry the filter residue at 40°C to obtain paeonol-hydroxypropyl-β-cyclodextrin inclusion compound; measure the encapsulation efficiency and the content of paeonol in the inclusion compound.
[0020] (2) Weigh danshensu, paeonol inclusion compound and excipients according to the weight indicated on the prescription, mix them, dissolve them with water for injection, filter, adjust the pH of the filtrate to 6.8-7.2, st...
