Embodiment 1
[0069] Example 1 Determination of the composition of the polysaccharide of sagebrush by high performance liquid chromatography
[0070] Specific steps are as follows:
[0071] (1) Preparation of the sample loading solution for the polysaccharide sample of the grass to be tested:
[0072] The polysaccharide of the grass polysaccharide was purchased from Wuhan Yuancheng Gongchuang Technology Co., Ltd. (CAS: 542-40-5, standard: enterprise standard, grade: food grade, content: 99%). Put 10 mg of grass polysaccharide sample into a 10 ml ampoule, add 2.0 mL of 2 mol / L trifluoroacetic acid into a 5 mL ampoule, seal the tube, hydrolyze with acid at 110 °C for 8 h, take out the trifluoroacetic acid to evaporate dry, and add 2.0 ml of water to reconstitute.
[0073] Sample solution derivatization: accurately pipette 250uL sample solution into 5mL EP tube, add 250uL 0.6 mol / L NaOH, 500 uL 0.4mol / L 1-phenyl-3-methyl-5-pyrazolone-methanol, react at 70℃ for 1h . Cool in cold water for 10...
Embodiment 2
[0081] Example 2 Preparation of celery microgel spheres by inverse emulsion method
[0082] Accurately weigh 50 mg of the polysaccharide from the grass, dissolve it in 0.5 mL of pH 3 water, and vortex until the polysaccharide is completely dissolved; accurately weigh 5 mg of ferric chloride metal ions. The sagebrush polysaccharide solution is mixed with metal ions.
[0083]Weigh 40 g of liquid paraffin and 1 g of Span80 into a 50 mL beaker, add a fully mixed solution of polysaccharide and iron, and stir magnetically for 1 h to fully crosslink polysaccharide and metal ions.
[0084] After 1 h, centrifuge at 1000 rpm for 2 min, separate the oil phase and the water phase, discard the upper oil phase, wash the microspheres with n-hexane and methanol each for 3 times in the lower water phase, and finally reconstitute the microgel spheres to 1 mL pH3. Distilled water.
[0085] The fairy grass microgel spheres were scanned by scanning electron microscope SEM. figure 2 As shown, t...
Embodiment 3
[0087] Example 3 Preparation of gel microspheres embedded with probiotics
[0088] 0.5 mL of 6×10 10 Cfu / mL probiotics were centrifuged at 3000 rpm at 4°C for 10 min, washed twice with normal saline, and reconstituted into 0.5 mL of normal saline. Dissolve 50 mg of grass polysaccharide in 0.5 mL of pH3 water, vortex until the polysaccharide is completely dissolved; accurately weigh 5 mg of ferric chloride, fully mix the grass polysaccharide solution, bacterial liquid and metal ions, and add 40 g of liquid paraffin. and 1 g Span80 in a 50 mL beaker, magnetically stirred for 1 h to fully cross-link the polysaccharides and metal ions, and centrifuged at 1000 rpm for 2 min after 1 h to separate the oil phase and the water phase, discard the upper oil phase, and use n-hexane for the lower water phase. The microspheres were washed three times with alkane and methanol each, and finally the microgel spheres embedded with probiotics were reconstituted into 1 mL of distilled water wit...
