Medicinal grade Dioica gum cas9000-65-1 use

Medicinal grade Erythris cas9000-65-1 use Erythorrhiza gum is a substance derived from the AstragalusgummiferLabillardiere and Astragalus genera distributed in western Asia, which is dried and coagulated as Erythorrhiza gum
.
Ashwagdalus gum consists of a mixture of water-soluble polysaccharides and non-water-soluble polysaccharides
.
60~70% of the yarrow gum sugar is composed of non-water-soluble parts; Ranthrin consists of a water-soluble part
.
After hydrolysis, yarrownose produces L-accharide, L-fucose, D-xylose, D-galactose and D-galactose acid
.
Ranunculus gum also contains small amounts of cellulose, starch, protein, and blazing residues
.
pH: 1% (w / v) aqueous solution pH is 5 ~ 6 acidity: 2 ~ 5 water content: ≤ 15% (w / w) particle size distribution: 50% (w / w) solubility of the powder pole through the 73.
7 μm mesh well: , insoluble in water, 95% ethanol and other organic solvents
.
Although insoluble in water, Cyperus sylvestris expands rapidly ten times by weight in hot and cold water, forming a viscous sol or semi-gel
.
Specific gravity: 1.

385Dynamic viscosity: The viscosity of the dispersion of Agaricus gum varies
with the grade and source of its material.
In general, at 20 °C, the viscosity of 1% (w/v) aqueous solution of Ashwagandha glue is 100~4000mPas (100~4000cP).

The viscosity increases with the increase of temperature and concentration, and decreases
with the increase of pH.
The solution has a large initial viscosity at a pH of 8 and a stable
viscosity value around pH 5.
The mucus extracted from
the legume plant Astragalus gummifer Labill.
【Properties】This product is a white or off-white translucent flat and curved ribbon sheet; Parallel fine stripes on the surface; Hard and flat and smooth; or white or off-white powder; In contact with water, it swells into colloidal mucus
.
【Identification】(1) Take an appropriate amount of this product, use 50% glycerol solution to pack tablets (General Principles 2001), add 1 drop of zinc iodine chloride test solution, place under the microscope to observe, visible round or oval starch particles, diameter of 4 ~ 10 μm, occasionally see 20 μm, mostly single particles, occasionally see polymerization particles
。 (2) Take about 0.
1g of this product, place it in a centrifuge tube, add 2ml of trifluoroacetic acid solution (6.
7→100), shake vigorously to form a gel, dense plug, place in a 120 °C oven for 1 hour, centrifuge, take the supernatant and transfer it to a 50ml round-bottom flask, add 10ml of water, and steam dry at 60 °C under reduced pressure; Add 1ml of 90% methanol solution to the residue to dissolve, filter, and take the filtrate as the test solution; Take 10mg of arabinose, rhamnose, xylose and galactose, add 5ml of 90% methanol solution to dissolve, shake well, and use it as a control solution
。 According to the thin layer chromatography (General Rule 0502) test, aspirate 5 μl of the test solution and the control solution, respectively, on the same silica gel G thin layer plate, with 1.
6% sodium dihydrogen phosphate solution - butanol - acetone (10:40:50) as the unfolding agent, secondary unfolding, the first unfolding distance is about 10cm, the second unfolding distance is about 15cm, take out, dry, spray with anisemaldehyde solution (take anisemaldehyde 0.
5ml, glacial acetic acid 10ml, methanol 85ml and sulfuric acid 5ml mixture, that is, obtained), Heat at 110°C until the spots are clearly visible and immediately inspected
.
The test solution shows spots of the same color in the corresponding positions of galactose, arabinose and xylose in the control solution, and must not show spots of the same color in the corresponding position of rhamnose
.
(3) Take about 0.
5g of this product, add 1ml of ethanol to soak in wet, add 50ml of water in divided doses, and shake while adding to form a uniform mucus
.
Take 5ml of mucus, add 5ml of water and 4.
5% barium hydroxide solution 2ml, shake well, generate white flocculent precipitation, heat, the solution and precipitate gradually appear yellow, dilute 2 drops of hydrochloric acid, shake well, precipitate dissolve, solution fade liquid paraffin Pharmaceutical grade 2020 Pharmacopoeia has a registration certificate quality inspection list Shanxi Jinyang excipient steviin Pharmaceutical grade excipient 2020 pharmacopoeia has a registration certificate quality inspection list Shanxi Jinyang excipient edetate disodium medicinal grade excipient is in line with the 2020 pharmacopoeia Part IV injection grade Shanxi Jinyang excipient triethyl citrate Pharmaceutical grade excipients 2020 pharmacopoeia has a registration certificate quality inspection list Shanxi Jinyang excipient insect ash granules pharmacopoeia filing 500g 5kg CDE filing quality inspection single business license Shanxi Jinyang excipient sorbitol 1kg 5kg pharmacopoeia filing Qualification full CDE filing quality inspection single business license Shanxi Jinyang excipient potassium dihydrogen phosphate 500g 25kg 2020 pharmacopoeia filing Shanxi Jinyang excipient sodium thiosulfate 1kg 25kg Shanxi Jinyang excipient sodium chloride 1kg Shanxi Jinyang excipient CDE filing quality inspection single business license zinc sulfate Elimination size 500g 25kg Shanxi Jinyang accessories
