Embodiment 1

[0007] Embodiment 1, the production technique of purslane polysaccharide, wherein: production technique is as follows:

[0008] (1) Get purslane, remove impurities, wash, cut into sections, and dry;

[0009] (2) soak in water for 30 minutes, and use microwave-assisted extraction for 3 times;

[0010] (3) Under vacuum heating conditions, concentrate under reduced pressure to purslane extract, add a small amount of ethanol, stir and mix, let stand for 24 hours, and take the precipitate; add appropriate amount of water to dilute the precipitate, add chloroform and n-butanol to mix Shake for half an hour;

[0011] (4) Dilute the purslane crude polysaccharide from which protein has been removed with an appropriate amount of water, and add it to the macroporous adsorption resin for eluting;

[0012] (5) Add activated carbon to the polyamide eluent for adsorption to remove activated carbon; then add hydrogen peroxide to mix, decolorize, heat to remove residual hydrogen peroxide; va...

Abstract

The invention relates to a production technology of purslane polysaccharide. The production technology comprises the following steps that: impurities in purslane are removed; purslane is washed, cut into segments, and dried; processed purslane is immersed in water for 30 minutes, and is extracted 3 times through microwave auxiliary extraction; in a vacuum heating condition, pressure reduction concentration is carried out on the purslane extract, such that a condensed purslane extract is obtained; a small amount of ethanol is added to the condensed purslane extract, and the mixture is stirred and well-mixed; the mixture is then stood for 24 hours, and a precipitate is obtained; the precipitate is diluted with a proper amount of water; chloroform and n-butanol are added to the diluted precipitate, and the mixture is mixed and oscillated for 30 minutes. Obtained protein-removed crude purslane polysaccharide is diluted with a small amount of water, and the diluted crude purslane polysaccharide is eluted in macroporous adsorption resin; active carbon is added to a polyamide eluate for adsorbing, and active carbon is removed; hydrogen peroxide is added to the obtained material, the mixture is well-mixed, decolored, and heated; residual hydrogen peroxide is then removed; the obtained material is vacuum-dried, such that purslane polysaccharide with a relatively high purity is obtained. The produced purslane polysaccharide has functions of immunity improving, tumor resisting, oxidation resisting, and aging resisting. The purslane polysaccharide has a hypoglycemic effect, and can be used for changing diabetes symptoms. Purslane polysaccharide has a good anti-tumor function, and can be applied in the development of anti-tumor medicines.

Description

Technical field: [0001] The invention relates to purslane, in particular to a process for producing purslane polysaccharide. Background technique: [0002] Purslane is an annual herbaceous plant of the genus Portulaca oleracea. Commonly known as longevity food, horse food and so on. Purslane is originally produced in temperate and tropical regions, and it is distributed all over the world except in alpine regions. It is a typical embodiment of the homology of medicine and food in my country. Not only has rich nutritional value, but also has various pharmacological functions such as antibacterial, blood lipid lowering, anti-oxidation, enhancing immunity, and anti-tumor. Polysaccharides are one of the four basic substances that constitute life and have important biological activities. Due to the fact that there are many research reports on purslane flavonoids in recent years, purslane polysaccharides are rarely reported. Invention content: [0003] The object of the prese...
