Abstract
The invention provides a polygonatum canaliculatum polysaccharide and a preparation method thereof. The polygonatum canaliculatum polysaccharide is extracted from the perennial liliaceae herbal plant of polygonatum canaliculatum and has the molecular weight of 5,000 to 100,000 Daltons. The solid polygonatum canaliculatum polysaccharide is off white or white. The monosaccharide consists of pyrane type beta-D-galactose, D-glucose and D-mannose. The product can be developed into medicines capable of reducing blood sugar and blood fat. The preparation method is reliable and feasible, and is suitable for the volume product without environmental pollution. The preparation method has low cost.
Description
Technical field
The present invention relates to a kind of polygonatum polysaccharide, relate in particular to its preparation method and medicinal use.
Background technology
Sealwort another name celestial being surplus grain, Rhizome of Tendrilleaf Solomonseal, chicken head ginseng etc. are Liliaceae Polygonatum per nnial herbs.Smell is gentle, and quality is moistened, and the moon of tonic lung is arranged, moisturize the effect of promoting the production of body fluid.In recent years, many to the active substance of sealwort research report, as polygonatum polysaccharide hypoglycemic, delay function such as life span of drosophila melanogaster.The sealwort main component has three major types: 1. be fat-soluble steroid saponin thing; 2. be flavones, green onion quinones; 3. be water soluble component-polygonatum polysaccharide.
Sealwort is widely used in clinically, and has got better therapeutic effect for traditional Chinese medicine commonly used.Control that cough, leprosy are itched, aspect such as diabetes, cerebral arteriosclerosis dizziness, anti-ageing, reducing blood-fat has good effect.And these effects be unable to do without water soluble component-polygonatum polysaccharide.As a kind of biological activity conditioning agent, polygonatum polysaccharide has great exploitation prospect.
Chinese patent literature CN1178799A discloses a kind of extracting method of polygonatum polysaccharide, is that filtrate adds organic deposition with sealwort lower alcohol lixiviate, filtration, and throw out is through getting the polygonatum polysaccharide crude product behind the filtering drying; The polygonatum polysaccharide crude product carries out chromatography three times with weak basic anion exchange resin and polyacrylamide gel again, gets the polygonatum polysaccharide elaboration through concentrated, freeze-drying again.This preparation method's technology is loaded down with trivial details, the equipment complexity, and the treatment time is long, and yield is low, and the cost height is not suitable for industrialization production.
Chinese patent literature CN1363611A discloses a kind of extracting method of polygonatum polysaccharide, is to extract with poach earlier, and centrifugal, the supernatant liquor concentrating under reduced pressure is used the ethanol alcohol precipitation again, and the ethanol alcohol precipitation is used in the throw out washing again, throw out with washing with alcohol after, vacuum-drying is pulverized again.The polygonatum polysaccharide purity that this kind method is extracted is not high, and impurity is more, influences the medicinal effect of polygonatum polysaccharide.
Summary of the invention
