Embodiment 1

[0017] The preparation of embodiment 1 paulownia tomentosa (original variant) paulownia total ethanol glycosides

[0018] The first step, with 5kg dried, pulverized Paulownia tomentosa (original variety) paulownia as raw material, add 20 liters of acetone aqueous solution with a volume ratio of 70%, extract 4 times with Soxhlet extraction, each 48h, filter, and the filtrate reduces Concentrated under pressure and freeze-dried to obtain the crude extract;

[0019] In the second step, add water with 2 times the mass of the crude extract, stir, add n-hexane with 3 times the mass of the crude extract for extraction, extract 4 times, separate, add chloroform with 3 times the mass of the crude extract to the remaining phase of the normal hexane extraction Extracting, extracting 4 times, separating to obtain the chloroform extraction phase and the chloroform extraction remaining phase;

[0020] In the third step, the remaining phase of the chloroform extraction is concentrated under...

Embodiment 2

[0021] The preparation of embodiment 2 paulownia tomentosa (original variant) paulownia total ethanol glycosides

[0022] The first step is to use 3 kg of dried and crushed paulownia tomentosa (original variety) paulownia as raw material, add 15 liters of acetone aqueous solution with a volume ratio of 80%, extract 3 times at room temperature, each time for 72 hours, filter, and concentrate the filtrate under reduced pressure , freeze-dried crude extract;

[0023] In the second step, add water with 3 times the mass of the crude extract, stir, add n-hexane with 4 times the mass of the crude extract for extraction, extract 5 times, separate, add chloroform with 4 times the mass of the crude extract to the remaining phase of the normal hexane extraction Extracting, extracting 5 times, separating to obtain the chloroform extraction phase and the chloroform extraction remaining phase;

[0024] In the third step, the remaining phase of the chloroform extraction is concentrated unde...

Embodiment 3

[0025] The preparation of embodiment 3 paulownia tomentosa (original variant) paulownia total ethanol glycosides

[0026] The first step is to use 1.5kg dried and crushed paulownia tomentosa (original variety) paulownia as raw material, add 5 liters of acetone aqueous solution with a volume ratio of 75%, ultrasonically assisted extraction 4 times, each time for 30min, filter, and the filtrate is concentrated under reduced pressure , freeze-dried crude extract;

[0027] In the second step, add water with 2.5 times the mass of the crude extract, stir, add n-hexane with 3 times the mass of the crude extract for extraction, extract 3 times, separate, add chloroform with 3 times the mass of the crude extract to the remaining phase of the normal hexane extraction Extracting, extracting 4 times, separating to obtain the chloroform extraction phase and the chloroform extraction remaining phase;

[0028] In the third step, the remaining phase of the chloroform extraction is concentrat...

Abstract

The invention belongs to the technical fields of natural medicines and natural foods, in particular to a method for preparing total glycollic glucoside by using royal paulownia (original variety) fortune paulownia wood as raw material and applications of the same to foods and medicines. The total glycollic glucoside of royal paulownia (original variety) fortune paulownia wood with the purity of 40-60 percent is prepared by using the royal paulownia (original variety) fortune paulownia wood as the raw material and extracting, leaching and separating the raw material, can remarkably eliminate DPPH free radicals and can be used for preparing oxidation-resistant foods and oxidation-resistant medicines.

Description

technical field [0001] The invention belongs to the technical field of natural medicine and natural food, and in particular relates to a method for preparing total ethanol glycosides from paulownia tomentosa (original variety) paulownia wood and its application in food and medicine. Background technique [0002] Reactive oxygen species (Reactive Oxygen Species, ROS) is one of the hotspots of current research. Active oxygen is the product of normal metabolic activities of cells, which can improve the bactericidal ability of phagocytes and neutrophils, regulate the body's metabolism, and participate in immune activities. Under normal circumstances, the production and elimination of active oxygen are in a state of balance. When the balance is broken, excessive reactive oxygen species will cause damage to macromolecules such as DNA and protein in the cell, resulting in cell and tissue damage, resulting in pathological conditions, and causing cardiovascular and cerebrovascular d...
