Abstract

The invention relates to an extract of lycium barbarum polysaccharide and a preparation method of the extract. The lycium barbarum polysaccharide obtained by the preparation method of cleaning, drying, crushing, removing impurities, extracting, decoloring, deproteinizing, condensing and purifying has the efficacies of reducing blood fat, reducing blood sugar, protecting liver, resisting tumor, resisting aging and the like; meanwhile, the preparation method of the lycium barbarum polysaccharide, disclosed by the invention, has the advantages of simple process, easiness in operation, higher yield and good quality, and facilitates the realization of industrial production and processing.

Description

technical field [0001] The invention relates to the field of plant extracts, in particular to a method for extracting wolfberry polysaccharides with various physiological functions such as lowering blood fat, lowering blood sugar, protecting the liver, anti-tumor, and anti-aging. Background technique [0002] Lycium barbarum (FructoLxcii) was first recorded in "Shen Nong's Materia Medica", which is the dry and mature fruit of Lycium barbarum. It is mainly distributed in Ningxia, Gansu, Shanxi, Xinjiang, Qinghai, Shaanxi, Inner Mongolia and other places. Lycium barbarum is a traditional Chinese medicinal material in my country. It plays an important role in traditional medicine in China, and its medicinal value has been highly praised by doctors of all ages. Li Shizhen of the Ming Dynasty recorded in "Compendium of Materia Medica" that "goji berry controls five internal evils, quenches thirst in heat, strengthens muscles and bones after long-term use, lightens body and does no...
