Abstract
The invention provides a method for purifying green tea polysaccharides, comprising the following steps: carrying out chromatography on the crude extract of the green tea polysaccharides by DEAE C-52 cellulose columns, carrying out gradient elution on the crude extract of the green tea polysaccharides by 0.1-0.5mol/L sodium chloride solution, tracking and detecting the green tea polysaccharides, collecting and merging all peak tubes, carrying out the chromatography on green tea polysaccharides by Sephadex G-100 gel columns, further purifying the green tea polysaccharides, eluting the green tea polysaccharides by 0.1mol/L sodium chloride solution, collecting and merging all peak tubes, dialyzing the green tea polysaccharides by using deionized water at low temperature for 48 hours, freezing and drying the green tea polysaccharides, and carrying out UV (ultraviolet) full-waveband scanning and infrared spectroscopy analysis on the purity and the nature of the green tea polysaccharides.
Description
Technical field: the purification process that the invention provides a kind of green tea polysaccharide.
Background technology: green tea and extract thereof have eliminates free radical, multiple biological activity such as anti-oxidant.Tea polysaccharide be from tealeaves, extract with protein bound acidic polysaccharose or acid glycoprotein together, be one of important physiologically active ingredient in the tealeaves.Chinese scholars has been carried out big quantity research to the contained polyose mixture of tealeaves, finds that tea polysaccharide has effects such as the body immunity of increasing, hypoglycemic, reducing blood-fat, minimizing atherosclerosis, anticoagulation, anti-oxidant, radioprotective.
The invention provides the method for a kind of tea polysaccharide crude extract, and its purity and character are carried out scanning of ultraviolet all wave band and Infrared spectroscopy through anionite DEAE C-52 cellulose chromatography, Sephadex G-100 gel filtration chromatography purifying tea polysaccharide.
Summary of the invention: the purification process that the objective of the invention is to provide a kind of green tea polysaccharide.
The present invention is achieved in that the tea polysaccharide crude extract through DEAE C-52 cellulose chromatography, and 0.1～0.5mol/L sodium chloride solution carries out gradient elution, and fraction collection is followed the tracks of and detected polysaccharide content, and record data are also drawn elution curve.Collect each peak pipe of merging, the long-pending dehydrated alcohol precipitation of triploid is spent the night, and centrifugal, the dissolving back is the SephadexG-100 gel filtration chromatography upward, 0.1mol/L sodium chloride solution wash-out, and fraction collection is followed the tracks of and is detected polysaccharide content, and record data are also drawn elution curve.Collect each peak pipe of merging, low temperature deionized water dialysis 48 hours, UV spectrum and Infrared spectroscopy are carried out in freeze-drying.
Description of drawings: Fig. 1 tea polysaccharide is through the elution curve of DEAE C-52 cellulose column
The Sephadex G-100 gel filtration chromatography elution curve of Fig. 2 tea polysaccharide
The ultraviolet all wave band scintigram of Fig. 3 tea polysaccharide
The infrared spectrogram of Fig. 4 tea polysaccharide
Embodiment: get 100mg tea polysaccharide crude extract, be dissolved in the 10mL 0.1mol/L sodium chloride solution, and ultrasonic 25min (35 ℃, 80W), 4 ℃ of frozen centrifugation 20min of 10000rpm, DEAE C-52 cellulose column carries out gradient elution with 0.1～0.5mol/L sodium chloride solution on the settled solution that obtains, and eluent flow rate is 60mL/h, fraction collection, every pipe 6mL, sulfuric acid-phynol method follow the tracks of and detect (490nm), and record data are also drawn elution curve.Collect and merge each peak pipe, the long-pending dehydrated alcohol precipitation of triploid is spent the night, centrifugal, after dissolving fully with 15mL 0.1mol/L sodium chloride solution, get supernatant liquor 5mL and go up the SephadexG-100 gel column, 0.1mol/L sodium chloride solution wash-out, eluent flow rate is 30mL/h, fraction collection, every pipe 3mL, sulfuric acid-phynol method is followed the tracks of and is detected (490nm), and record data are also drawn elution curve.Collect and merge each peak pipe, low temperature deionized water dialysis 48 hours, freeze-drying.Carry out the scanning of ultraviolet all wave band (190-400nm) and KBr compressing tablet infrared scan (500-4000cm
-1).
