Abstract

The invention provides a buckwheat composition extract with broad-spectrum antibacterial property, which is prepared from the following components in parts by weight: 20 to 30 parts of buckwheat, 5 to 8 parts of radix zanthoxyli, 10 to 12 parts of folium crataegi and 5 to 8 parts of folium hippophae rhamnoides. The extract is a water extraction product. The invention further provides a method for preparing the buckwheat composition extract and application of the buckwheat composition extract. The buckwheat composition has the advantages of being wide in antibacterial spectrum and excellent in antibacterial performance, has an efficient antibacterial effect on more than 30 kinds of bacteria, and has the application potential as an efficient antibacterial agent. According to the invention, the antibacterial defects of the buckwheat extract are overcome, and the application value of buckwheat is expanded.

Description

technical field [0001] The invention belongs to the field of antibacterial technology, and in particular relates to a broad-spectrum antibacterial buckwheat composition extract, preparation method and application. Background technique [0002] Buckwheat is a dicotyledonous plant, which has the characteristics of strong adaptability, can grow in a variety of environments, short growth cycle, and can be planted in spring, summer and autumn. Its shape is different from that of wheat, with erect stems, longitudinal ribs, and leaves Triangular or egg-shaped, corymb-shaped flowers, triangular grains, and black hard shell bran outside. As a small grain crop, buckwheat can be used to make noodles, jelly and other foods. [0003] The cultivation of buckwheat is widely distributed in my country, and it is planted in the southeast and northwest. The perennial planting area in my country is about 1 million square hectares, and the output is about 700,000 tons. Not only the annual outpu...
