Problems solved by technology

[0006] Sodium selenite is a typical selenium supplement health product, but due to its single ingredient, the liver protection effect is limited, and the range between its efficacy dose and toxic dose is narrow, which has certain safety hazards
Selenium-enriched plants and selenium-enriched yeast on the market are mainly organic selenium components with high safety, but a single component has limited effects on comprehensively regulating human health and protecting the liver

Abstract

The present invention provides a selenium-enriched extract of the broken cordyla leaf of the catalina, which is extracted from the above-ground part of the stem-leaf of the cordy-leaf broken planta. , add water to extract, and filter to obtain the filter residue and filtrate. The filter residue was extracted again under the same conditions, and the filter residue and filtrate were obtained by filtration. The two extracted filtrates were combined and concentrated to obtain a concentrate. Add ethanol to the concentrated solution, and let the alcohol settle overnight. The liquid phase and solid phase after alcohol precipitation were separated by filtration. The solid phase was dissolved in water, ethanol was added, and the alcohol precipitation was allowed to stand overnight. The liquid phase and solid phase after alcohol precipitation are separated by filtration, and the solid phase is dried to obtain the target product. By adopting the two-step alcohol precipitation method, the total selenium content in the obtained selenium-enriched Viola leaf broken rice chestnut extract reaches more than 2800 mg / kg, and the organic selenium content reaches more than 97%. Further, the present invention also provides the application of the above selenium-enriched Corydalis cordylae broken rice chestnut extract in liver protection, which has remarkable curative effect and can be used to develop a series of functional foods with a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a selenium-enriched extract of Corydalis chinensis and its application in liver protection. Background technique [0002] The selenium-accumulating plant Violet-leaf scutellaria is a perennial plant of the family Cruciferae. It is mainly distributed in alpine areas. Its tender stems and leaves are edible, and the taste is fresh and delicious. It is an excellent wild vegetable resource. In recent years, in the typical selenium-enriched area of ​​Enshi, natural Viola-leaved plants with high selenium content have been found, and the selenium content can reach hundreds of ppm. [0003] Selenium is an essential trace element for the human body. It has long been considered as an important food source of antioxidants. It is known as "the fire of life", "the king of anti-cancer", "the patron saint of the heart" ". There are many physiological functions of selenium, and they can...
