Problems solved by technology

Burdock is planted in a large area in my country, mainly using the fruit and roots, but there are few reports on the use and research of burdock leaves, especially about the essential oil of burdock leaves. Most of the burdock leaves are discarded as waste, resulting in a waste of resources and environmental pollution

Abstract

The invention relates to a method for simultaneously extracting burdock leaf essential oil and chlorogenic acid. The method comprises the following steps: (1) obtaining burdock leaf slurry; (2) performing ultrasonic wave-enzymolysis; (3) performing CO2 supercritical fluid extraction, wherein the collected extract is burdock leaf essential oil; (4) adding the liquid extracted in the step (3) into a D101B resin adsorption column for adsorption; and (5) carrying out macroporous resin adsorption according to the method in the step (4), collecting the eluent of the target product, concentrating under reduced pressure, and recrystallizing the concentrated solution to obtain the chlorogenic acid product. The invention provides the method for simultaneously extracting the essential oil and the chlorogenic acid from the burdock leaves, the yield of the essential oil and the yield of the chlorogenic acid are high, and the maximum resource utilization is realized.

Description

technical field [0001] The invention relates to a method and application for simultaneously extracting burdock leaf essential oil and chlorogenic acid. Background technique [0002] The information disclosed in this background section is only intended to increase some understanding of the general background of the present invention, and is not necessarily to be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Burdock is a biennial herbaceous plant of Compositae, also known as mouse sticky grass, bullwhip, bat thorn, oriental radish, etc. Burdock is rich in nutrition, rich in cellulose, inulin, protein, calcium, iron, phosphorus and other minerals, multivitamins and a variety of biologically active substances, and has excellent health care functions. Fruits, roots, stems and leaves can be used. Burdock is planted in a large area in my country, mainly using the fruit and...
