Embodiment 1
[0046] Embodiment 1, the establishment method of polysaccharide standard fingerprint of Ganoderma lucidum spore powder
[0047] 1. Instruments, reagents and samples
[0048] 1.1 Instrument
[0049] Agilent 1100 HPLC equipped with diode array detector (DAD) and Agilent chromatography workstation.
[0050] 1.2 Reagents and samples
[0051] Monosaccharide standard products: glucose (Glc, 99%), mannose (Man, 99%), galactose (Gal, ≥99%) were purchased from Shanghai Chemical Reagent Company; rhamnose (Rha, ≥99%), Fucose (Fuc, ≥99%), glucuronic acid (GlcUA, ≥99%), and galacturonic acid (GalUA, ≥97%) are all products of Sigma-Aldrich in the United States; xylose (Xyl, 98%) , glucosamine (GlcN, 98%), and galactosamine (GalN, 99%) are all products of ACROS ORGANICS in the United States; ribose (Rib, >99.0%) and arabinose (Ara, 99%) are all purchased from Xiamen Xinglong Da Biochemical Reagent Co., Ltd. Derivatization reagents: 1-phenyl-3-methyl-5-pyrazolinone (PMP), purity 99% (Acr...
Embodiment 2
[0077] Example 2, polysaccharide fingerprint analysis of Ganoderma lucidum spore powder sample from a certain origin in Shandong
[0078] 1. Extraction of Ganoderma lucidum spore powder polysaccharide
[0079] Accurately weigh 700 mg of the broken Ganoderma lucidum spore powder sample into a 50 mL centrifuge tube, add 30 mL of ultrapure water, ultrasonicate for 60 minutes in a water bath at 60°C (power 300 watts), and centrifuge after cooling. The residue is washed with a small amount of ultrapure water and centrifuged. The two supernatants were combined, dialyzed with ultrapure water for 12 hours, concentrated in vacuo at 60° C., added ultrapure water to 5 mL as a crude polysaccharide aqueous solution, to be tested.
[0080] 2. Partial acid hydrolysis of Ganoderma lucidum spore powder polysaccharide
[0081]Draw 100 μL of the crude polysaccharide aqueous solution into a 5 mL stoppered graduated test tube, add 100 μL of 0.5 mol / L TFA, fill with N 2 Seal the tube, hydrolyze a...
Embodiment 3
[0088] Example 3, Fingerprint analysis of unbroken Ganoderma lucidum spore powder sample from a place in Jilin
[0089] 1. Extraction of Ganoderma lucidum spore powder polysaccharide
[0090] Accurately weigh 500mg of unbroken Ganoderma lucidum spore powder sample into a 50mL centrifuge tube, add 30mL ultrapure water, oscillate in a water bath at 95°C for 2 hours at a constant temperature, then ultrasonicate for 50 minutes in a water bath at 70°C (power 300 watts), and centrifuge after cooling , the following operations are the same as the extraction steps of Example 1.
[0091] 2. Partial acid hydrolysis of Ganoderma lucidum spore powder polysaccharide
[0092] Draw 100 μL of the crude polysaccharide aqueous solution into a 5 mL stoppered graduated test tube, add 100 μL of 0.5 mol / L TFA, fill with N 2 Seal the tube and hydrolyze at 100°C for 1 hour; after cooling, open the cap, dry in vacuum at 50°C to remove TFA, add 200 μL of ultrapure water to dissolve the residue (hydro...
