Problems solved by technology

②When concentrated to a certain extent, the feed liquid is very easy to produce foam and run out of material
Different concentration methods have different advantages and disadvantages, but their overall characteristics are high energy consumption and easy loss of active ingredients in the extraction process of active ingredients of Eucommia, which not only reduces the enrichment of active ingredients of Eucommia, but also increases the extraction of active ingredients of Eucommia. The cost in the process also hinders the effective absorption of the active ingredients of Eucommia by the human body

Abstract

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.

Description

Technical field: [0001] The invention belongs to the field of natural product extraction, and in particular relates to eucommia fine powder extracted from eucommia bark and leaves, which can be used as medicine and health products and feed additives, and also relates to a preparation method of the eucommia fine powder. Background technique: [0002] Eucommia ulmoides Oliv. is a rare and precious woody medicinal plant unique to my country. It is called a "living fossil plant" and is also a relict plant of the Tertiary Period that only exists in my country. , mainly located in Gansu, Shaanxi, Shanxi, Henan, Hunan, Hubei, Sichuan, Yunnan, Guizhou, Guangxi, Jiangxi, Fujian and other provinces and autonomous regions from plains to hills and mountains at an altitude of 1,690 meters. The natural center is in central China. Since the 1980s, driven by the production upsurge of Eucommia, various places have taken the development of Eucommia as an important measure to adjust the structu...
