Abstract

The invention relates to the technical field of medicine, in particular to a preparation method of wild pineapple polysaccharide. The preparation method comprises the following steps: steaming and drying the wild pineapple fruit to obtain dried wild pineapple fruit; pulverizing the dried wild pineapple fruit, and extracting the dried fruit powder with water, concentrating, drying and pulverizing to obtain the wild pineapple water extract; The pineapple water extract is dissolved in water, centrifuged, and the supernatant is filtered to obtain a clear liquid; the clear liquid is subjected to alcohol precipitation, the precipitate is dried, crushed and sieved to obtain the primary product; the primary product is dissolved in water, and after filtration Use neutral protease to carry out enzymatic hydrolysis, inactivate the enzyme, and obtain the retentate after ultrafiltration; concentrate the retentate, carry out alcohol precipitation again, dry and pulverize. The purity of the wild pineapple polysaccharide extracted by the invention reaches more than 90 percent, the biological activity of the wild pineapple polysaccharide is improved, and the effect of lowering blood sugar and blood fat of the wild pineapple polysaccharide is enhanced.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a preparation method of wild pineapple polysaccharide. Background technique [0002] Wild pineapple is the fruit of the pandanus plant. Because the shape is similar to pineapple, Lingnan folks call it wild pineapple. Wild pineapples are widely distributed in Hainan and are rich in resources. They can be eaten as wild fruits among the people. The pulp is sweet, but the pulp is rich in vascular tissue and has a poor taste. Therefore, it is not very popular. It is used for the treatment of diseases and coughs in Hainan . The roots, leaves and other parts of Pandanus can be used for medicinal purposes. It has the functions of clearing away heat and dampness, diuresis, relieving the exterior, promoting qi and calming the liver. Modern pharmacological studies have shown that the active ingredients of wild pineapple can regulate lipid metabolism in diabetic mice, reduce fat accumula...
