Problems solved by technology

At present, there are hot water extraction, organic solvent extraction, supercritical carbon dioxide extraction or ultrasonic-assisted extraction to extract the active ingredients of bamboo leaves. Although the existing supercritical carbon dioxide extraction or ultrasonic-assisted extraction can improve the extraction rate of active ingredients, However, there are still some beneficial ingredients remaining in the residue. If this part of the residue can be further utilized, the utilization rate of bamboo leaf resources will be greatly improved.

Abstract

The invention discloses a bamboo leaf extract and a preparation method and application thereof, and relates to the technical field of natural product extraction. The bamboo leaf extract comprises a primary bamboo leaf extract obtained by primary extraction with bamboo leaves as raw materials, and a secondary bamboo leaf extract obtained by carrying out secondary processing extraction on primary extraction residues serving as raw materials. The bamboo leaf extract comprises the following raw materials: bamboo leaves, compound enzyme, amino acid, reducing sugar and auxiliaries. The compound enzyme comprises one or more of acidic cellulase, pectinase, beta-glucanase, acidic xylanase, beta-glucosidase and neutral protease, and the amino acid comprises one or more of phenylalanine, tyrosine and proline. According to the bamboo leaf extract and the preparation method and application thereof, secondary processing extraction is carried out on residues obtained after primary extraction of bamboo leaves, resources are fully utilized, and meanwhile the quality of the extract is improved to a certain degree.

Description

technical field [0001] The invention relates to the technical field of natural product extraction, in particular to a bamboo leaf extract and its preparation method and application. Background technique [0002] Bamboo is a perennial evergreen plant of the Poaceae Bambooideae. There are more than 60 genera and more than 1,200 species of bamboo plants in the world. China is the main production area of ​​bamboo in the world and one of the countries with the richest bamboo resources in the world. The types, area and volume of bamboo forests are all in the forefront of the world, and the utilization value of bamboo leaves has gradually been recognized by people. Bamboo leaves are rich in various active substances such as polysaccharides, flavonoids, polyphenols, proteins, amino acids and mineral elements, and also rich in cellulose components. [0003] There are many researches on the extraction and functional activity of plant active ingredients in China, but most of the resea...
