Abstract

The invention provides a preparation method of a traditional Chinese medicine extract. The raw materials of the Chinese medicine extract are composed of: 30-60 parts by weight of astragalus, 9-15 parts by weight of Ligustrum lucidum, 9-30 parts by weight of motherwort, 3-10 parts by weight of black plum parts by weight, 2-9 parts by weight of Coptidis Rhizome, 1-5 parts by weight of Cinnamon, and 3-9 parts by weight of Budhimonica; the preparation method includes: extracting volatile oil from cinnamon, and inclusion of volatile oil with β-cyclodextrin; astragalus, privet Seed and Budapest japonica are extracted with ethanol solution I of 10%-100% concentration by volume; Ume and cinnamon dregs, astragalus, Ligustrum lucidum and Budmija flower dregs are extracted with water; Motherwort and Coptis chinensis use volume percentage concentration 10%‑100% ethanol solution II for extraction; the extracted extracts of each part are combined and dried to obtain dry extract powder, added with volatile oil clathrate, mixed evenly, and obtained. The preparation method of the invention significantly improves the content of active substances and pharmacological effects of the traditional Chinese medicine extract.
