Technical field
The present invention relates to total reducing sugar detection technique field, in particular to a kind of measurement method of total reducing sugar.
Background technique
The concentration of total reducing sugar in solution is detected in each research field, such as petrochemical industry, medicine, food field are all particularly significant
's.At present there are many kinds of the analysis methods of detection total reducing sugar, such as chromatography, capillary electrophoresis, infra-red sepectrometry, nuclear magnetic resonance
Method, evaporative light-scattering spectroscopic methodology, colorimetric method etc..But these methods have cost more and greatly, excessively rely on expensive instrument, time-consuming, inspection
The disadvantages of surveying high operation requirements.
Colorimetric method becomes detection always because of the advantages that its operation is relatively easy, testing cost is cheap, detecting instrument is relatively cheap
The common method of sugar；The basic principle is that the product and the reaction of specific color developing agent after saccharide compound is hydrolyzed generate to have and add lustre to
The derivative compound of group, this derivative can generate absorption at the Vis scan wave band of uv-vis spectra scanner
Peak.Phenol-sulphate acid method is hydrolyzed dewatered in concentrated sulfuric acid as the most widely used colorimetric method using saccharide compound
Product can generate a kind of coloured compound with phenol reactant, and this compound has maximum absorption band, but the party at 490nm
Method still has following problems: 1) color developing agent phenol used in has very big harm to the health of human body, and phenol steam is to skin
Skin, eyes and respiratory system are all corrosive, and contact phenol will cause scytitis or second level very to skin repeatedly or for a long time
To burning for three-level；Same sucking phenol will cause pulmonary edema for a long time or repeatedly, influence central nervous system.2) reaction time
Too long, the time for generally requiring 30min or more could fully reacting.3) accuracy is low；Make standard curve with glucose, and it is practical
Carbohydrate complicated composition in the sample of life, not only contain glucose, also contain acid sugar, due to the phenol sulfuric acid of various carbohydrates
The molar absorptivity rate difference of the substance generated after derivatization is larger, and especially neutral sugar and acid sugar is the most significant, so cause
The resultant error of detection is larger.
Patent publication No. CN105510257A discloses a kind of method for measuring total sugar content in shenxiong glucose injection,
1) reference substance solution preparation step: precision weighs glucose control product 10mg, sets in 100ml measuring bottle, adds water to make to dissolve and dilutes
To scale, the reference substance solution to get 0.1mg/ml is shaken up；2) preparation step of test solution: precision measures ginseng rhizome of chuanxiong grape
Sugared injection 0.5ml, sets in 25ml volumetric flask, adds water 5.0ml, then plus 2.0ml hydrochloric acid, shake up；It hydrolyzes 1 hour, puts at 95 DEG C
It is cold, scale is added water to, is shaken up；The accurate 1.0ml that measures is set in 10ml measuring bottle again, is diluted with water to scale, is shaken up to get test sample
Solution；3) sulfuric acid solution preparation steps: 760ml sulfuric acid is diluted with water 1000ml to obtain the final product；4) Anthrone Sulphuric acid solution prepares step
It is rapid: 0.2g anthrone being taken to be dissolved in 100mL sulfuric acid solution.The same day, which prepares, to be used；5) determination step: precision measures test solution
1.0mL is set in 10mL tool plug test tube, is added Anthrone Sulphuric acid solution 8.0mL prepared by step 4) after adding water 1ml, is dipped in rapidly
It is cooling in ice-water bath, then in 100 DEG C of water-baths, accurately boil l0min taking-up, be cooled to room temperature to obtain measurement test sample with ice-water bath
Solution；Precision is measured for reference substance solution 1.0mL, is set in 10mL tool plug test tube, adds anthracene prepared by step 4) after adding water 1ml
Ketone-sulfuric acid solution 8.0mL, is dipped in rapidly in ice-water bath cooling, then in 100 DEG C of water-baths, accurately boils l0min taking-up, uses ice
Water-bath cooling to room temperature must measure reference substance solution；Its absorption value is measured in 626nm with ultraviolet-uisible spectrophotometer, calculates ginseng
Total sugar content in rhizome of chuanxiong glucose injection.But it also belongs to poisonous substance using anthrone, still without solve it is toxic harm and
The problem of multiple types sugar part influences the accuracy of measurement.
(Su Yushun et al. is in 2011 for document " application of the UV-VIS spectrophotometry in plant polyose assay "
Year deliver) and document " progress of uronic acid and neutral sugar analyzing detecting method in plant polyose " (Chen Hui et al. in
Deliver within 2011) all illustrate that the middle resulting result difference of different color developing agents is larger, and material molecule is to different wave length and spy
The radiation absorption degree of given wavelength is different and different material molecule is also different to the radiation absorption degree of certain wave strong point,
Thus illustrate that the use of color developing agent and sample multicomponent will affect the accuracy that total sugar content detects.
Summary of the invention
In order to solve the above technical problems, The present invention provides a kind of measurement methods of total reducing sugar.
