The invention discloses
eucommia ulmoides
fine powder and a preparation method thereof. The
eucommia ulmoides
fine powder comprises the following components: larger than or equal to 15 percent of total
sugar, larger than or equal to 5 percent of
chlorogenic acid, larger than or equal to 15 percent of total flavone, larger than or equal to 1.8 percent of
geniposidic acid, larger than or equal to 0.8 percent of
aucubin, less than or equal to 6.0 percent of water and trace elements such as B, Ca, Cu, Mg, Mn, P, Se, Zn, Na, K and Fe. According to the preparation method, the
eucommia ulmoides
fine powder is efficiently extracted from
eucommia ulmoides leaves and
eucommia ulmoides bark and a
membrane technology is introduced for separation, concentration, decoloration and the like, so that the labor and time are reduced, the product quality and yield can also be improved, the temperature of the extraction process is low, and the damage of high temperature heating on effective components is avoided. In addition, the phenomenon that the
eucommia ulmoides fine
powder is insoluble in water the second time is avoided. The eucommia ulmoides fine
powder belongs to a natural
health food preparation, is safe and non-toxic, and is suitable for the industries such as
medicine, health care products and food antioxidants.
Eucommia ulmoides gum can be continuously extracted out from extractive residue after extraction of the eucommia ulmoides fine
powder, and the economic benefit of high-value using of eucommia ulmoides is effectively improved.
