Method for preparing aucubin by adopting decoction dregs after extracting chlorogenic acid from folium cortex eucommiae

Abstract

The invention relates to a method for preparing aucubin by adopting decoction dregs after extracting chlorogenic acid from folium cortex eucommiae. The method comprises the steps: extracting an aucubin crude extract from decoction dregs of folium cortex eucommiae after extracting chlorogenic acid by utilizing edible ethanol, and separating and purifying the aucubin crude extract by utilizing NKA-2 macroporous resin to obtain an aucubin extract. According to the method, the aucubin is safely and toxicity-freely extracted and separated by adopting edible ethanol, so that can the aucubin extracts in different purity specifications be safely and effectively produced in an industrialization manner and can the waste be changed into treasure, but also the high-value utilization of safe, simple, reasonable and economical eucommia ulmoides resource and the industrialized production of series products can be actually realized, and the green production concept and strategy of cycling economy can be adequately reflected.

Description

technical field [0001] The invention relates to a green chemical process technology for preparing aucubin from the dregs of eucommia leaves after extracting chlorogenic acid, especially a kind of aucubin in the dregs after extracting chlorogenic acid from eucommia leaves by using edible ethanol Then use the NKA-2 macroporous resin to separate and purify the green separation and purification method of aucubin. Background technique [0002] Eucommia (Eucommia Ulmoides Olive) is a plant of the genus Eucommia in the Eucommia family, a deciduous tree. my country has a very wide area suitable for the growth of Eucommia, and more than 10 million hectares of land can be used to plant Eucommia. At present, the national Eucommia cultivation area is about 350,000 hectares, accounting for More than 99% of the total planting area of ​​Eucommia ulmoides has unique resource advantages. Our country can produce 4 million tons of leaves every year. [0003] The chemical name of aucubin (aucub...

AI Technical Summary

Problems solved by technology

Obviously, although the above-mentioned extraction, separation and purification method of Eucommia leaf aucubin can prepare Eucommia leaf aucubin extract with a certain purity and yield, due to the limitation of technical means and the use of a large amount of toxic Organic solvents or chemical preparations make the product obviously have defects such as poor safety or low purity and yield, high equipment cost, and insufficient product quality and market competitiveness.

[0009] At present, most of the utilization of eucommia leaves is limited to the extraction and utilization of eucommia chlorogenic acid, and the residual medicine residue after extraction is directly discarded, which not only fails to make full, efficient and reasonable use of eucommia leaf resources, but also causes serious environmental pollution.
