Embodiment 1

[0028] The extraction steps of the present invention are as follows:

[0029] 1. Collect dead or fallen walnut leaves in Jinan or Tai'an area, clean them, dry them naturally until they are yellowish-brown, and store them in a dry place for later use;

[0030] 2. Weigh 2.5kg of walnut leaves and put them into the heating container (reactor), compact them so that the waste leaves are tightly placed in the heating container. After pressing the waste leaves, add water until the walnut leaves are covered by 10-20cm, generally about 15cm , soaked at room temperature for 2 hours;

[0031] 3. Install a condenser on the heating container, pass condensed water, pass nitrogen gas to the heating container, replace all the air in the container, and start heating the container in a nitrogen atmosphere until it boils, maintain the boiling state, and start Collect the distilled components; when the water level in the heating container drops to 2-4cm below the walnut leaves, add water to the ...

Abstract

The invention discloses a preparation method of an aqueous walnut leaf extract, a walnut leaf alcohol solution obtained by using the preparation method and an application of the walnut leaf alcohol solution. The preparation method comprises the following steps: drying walnut leaves, soaking the walnut leaves with water, then, heating, boiling, and collecting distilled components to obtain the aqueous walnut leaf extract. Aiming at the problems of many walnut waste leaves and insufficient utilization of the walnut waste leaves, the invention provides a simple, feasible, clean and efficient preparation method for the research of effective medicinal components of the walnut leaves, wherein in the method, the waste walnut leaves are used as raw materials, the effective components in the walnut leaves are extracted by using a simple boiling and distilling method, and waste materials are changed into the things of value. The obtained walnut leaf alcohol solution is proved to have the effects of inhibiting bacteria and inhibiting the regeneration of cancer cells, and can be used in the field of anticancer drugs.

Description

technical field [0001] The invention relates to a method for extracting effective components of walnut leaves, in particular to a method for preparing water extract of walnut leaves, the obtained walnut leaf alcohol solution and the application of the walnut leaf alcohol solution, belonging to the technical field of plant effective component extraction. Background technique [0002] Walnut, also known as walnut and Qiang peach, is a deciduous tree of the genus Juglandaceae. Because of its nutritious kernels and unique flavor, it is one of the four major dried fruits in the world; and because of its high oil content and delicate oil taste, it has become a high-grade edible and industrial oil, and it also has medical and health care functions. The wood texture of walnut is hard and beautiful, and it is a precious wood for military industry, high-end furniture, carving crafts, musical instruments, etc. Its bark, fruit peel, root bark, branches and leaves all contain a large am...
