摘要
(CN105218601) 本​发明​公开​了​一种​从​柿子​中​提取​单宁​的​方法,包括​以下​步骤:1)将​柿子​去皮,破碎,加入​乙醇​提取,将​提取​液​过滤,取​滤液​备用;2)将​滤液​浓缩,加入​95v%乙醇,放置​过夜,离心,取​上​清液;3)将上​清液​过​AB-8​大​孔​树脂,先用​水洗​柱​至​无色,然后​用​乙醇​洗脱,收集​乙醇​洗脱​液;4)将​乙醇​洗脱​液​浓缩​回收​溶剂,得到​浸膏,加水​溶解,过滤,取​滤液​通过​截留​分子量​为​400~500​的​中空​纤维​膜,收集​截留​液​备用;5)将​截留​液​通过​截留​分子量​为​13000~15000​的​中空​纤维​膜,收集​透过​液,干燥,即为​柿子​单宁​粉末。本​发明​提取​的​柿子​单宁​具有​很好​的​抑制​变形​链球菌​的​作用,可用​于​防龋​齿。

(CN105218601) 1. A method for extracting tannin from persimon, characterized in: comprising the steps of: 1) will be persimon peeling, crushing, ethanol was added to extract, the extract is filtered, take the backup; 2) the filtrate was concentrated, added 95v % ethanol, allowed to stand overnight, centrifugation, the supernatant; 3) the supernatant was too AB -8 macro porous resin, to a colorless column was washed with water, followed by ethanol eluted, collecting ethanol eluent; 4) recovering the eluate was concentrated ethanol solvent will, Gnetum extract obtained, adding water was dissolved, filtered, take the filtrate by molecular weight cutoff of 400-500 of hollow fiber membranes, standby retention liquid collected; 5) will concentrate by fractional molecular weight of 13000-15000 of hollow fiber membranes, the permeate was collected, dried, powdered tannin is the persimon.
