| titleOfInvention | A method of preparation has the polyphenol polymer of alpha-glucosaccharase enzyme inhibition activity from vine tea |
| abstract | A method of preparation has the polyphenol polymer of alpha-glucosaccharase enzyme inhibition activity from vine tea, technical solution of the present invention main points are: a method of preparation has the polyphenol polymer of alpha-glucosaccharase enzyme inhibition activity from vine tea, (1) prepared by vine tea water extract, vine tea is placed in boiling water, it is soaked for a period of time, filtrate is freeze-dried by filtered through gauze, obtains vine tea water extract；(2) column chromatography for separation: 50% methanol aqueous solution of Ampelopsis grossedentata extrat obtained by step (1) is dissolved, use upper chromatographic column, impurity first is washed away with certain density methanol aqueous solution, is then eluted with certain density aqueous acetone solution, and collect eluent；(3) film is dialysed, and elution solution rotary evaporation in vacuo obtained by step (2) is removed acetone, obtained aqueous solution is put into bag filter, is dialysed certain time with water, and the sample liquid in collecting bag, freeze-drying obtains polyphenol polymer.Simple production process of the invention, cost is relatively low. |
