Abstract

The invention discloses a separation and extraction method and application of thick root nettle polysaccharide, the molecular weight range of the thick root nettle polysaccharide is 11000-20000, and the thick root nettle polysaccharide is composed of rhamnose, semi Lacturonic acid, galactose and arabinose form; The mass ratio of rhamnose, galacturonic acid, galactose and arabinose in the described thick root nettle polysaccharide is 1:1.0-1.4:0.4-0.8:0.4-0.8 ; the total sugar content in the thick root nettle polysaccharide is 40-90%; the uronic acid content in the thick root nettle polysaccharide is 20-50%. The present invention relates to the technical field of extracting nettles with thick roots, and specifically provides a method for separating and extracting nettles with thick roots polysaccharides and its application. For the first time, nettles with thick roots is separated, extracted and purified to obtain a nettle with thick roots polysaccharides. It is found that it has the effect of activating immune cells and enhancing immunity.

Description

technical field [0001] The invention relates to the technical field of crude root nettle extraction, in particular to a separation and extraction method and application of crude root nettle polysaccharide. Background technique [0002] Nettle (Urtica L.) is an annual or perennial herb of the Angiosperm family, Urtica, and Urtica, and is a commonly used ethnic medicine and folk medicine. This genus has a long history of medicinal use in my country. It has been recorded as early as in "Compendium of Materia Medica", "Ben Cao Jing", "Supplement to the Compendium", and "Brief Notes on Prescriptions of the Ministry of Yi". It has the functions of calming shock, eliminating accumulated laxatives, and detoxifying. Nettles are abundant in my country. Among the 36 species of nettles known in the world today, 23 are distributed in various regions of my country. Among them, the rough root nettle (Urticamacrorrhiza Hand.-Mazz.) is unique to Yunnan. The variety, commonly known as tiger h...
