The invention provides a preparation method of an acanthopanax biochemical
capsule containing components capable of inhibiting dysmenorrhea, relates to a preparation method of a biochemical
capsule, and aims to solve the technical problem that the acanthopanax biochemical
capsule has an unobvious effect on dysmenorrhea. The method comprises the following steps of: 1,
drying ligusticum wallichii at 50-80 DEG C, controlling the
moisture to be 10% or below, and crushing into
fine powder; 2, decocting
angelica sinensis, peach kernel, liquorice and rhizoma zingiberis for 1-3 times, adding water which is 2-4 times of the total weight of the raw materials during each decoction, decocting for 1-2.5 hours, filtering in batches, combining the filtrates, performing
spray drying, and collecting the medicinal
powder; and 3,
drying acanthopanax extract under reduced pressure, and crushing into
fine powder; and 4, mixing the
fine powder obtained in the steps 1-3 with the medicinal
powder, thereby obtaining the product. According to the invention, the
ligusticum wallichii
powder and acanthopanax extract are not combined with the extracting solution of four medicinal materials, namely
angelica sinensis, peach kernel, liquorice and rhizoma zingiberis, so that the content of a component capable of inhibiting dysmenorrhea factors in the extracting solution is improved, and the
curative effect of the acanthopanax biochemical
medicine on dysmenorrhea is enhanced. The invention belongs to the field of preparation of acanthopanax biochemical capsules.
