Description

technical field [0001] The invention belongs to the technical field of extracting Chinese medicinal materials, and in particular relates to a preparation method of Lingxiaohua extract. Background technique [0002] Lingxiaohua is not only an ornamental flower, but also a medicinal plant. Lingxiaohua, bitter and sour in taste, slightly cold in nature, returns to liver and pericardium meridians. [0003] The appearance of Lingxiaohua extract is brown solid powder, soluble in water, methanol, ethanol, etc., but insoluble in solvents such as ether, petroleum ether, etc. The chemical composition of Lingxiaohua extract is relatively complex, and the identified ones are: apigenin, β -Sitosterol, etc., oleanolic acid, cinnamic acid, triuncontanol, 15-mercapto-2-pentadecanone, etc. [0004] Lingxiaohua extract is an environmentally friendly product that is beneficial to human health. It has the effects of promoting blood circulation and removing blood stasis, cooling blood and expe...
