Embodiment 1
[0013] Embodiment 1: the preparation of yam glycoprotein
[0014] Take 1000g of yam raw medicine and crush it into fine powder, add 2 times the amount of water to heat, the temperature is 50°C, extract twice, each time for 2 hours, filter and combine the two extracts, concentrate the extract to 50%, and the concentration to 95 Add % ethanol to the concentrated solution to make the alcohol content reach 60%. After the white precipitate appears, let it stand for 3-6 hours, separate the precipitate from the supernatant, and continue to add 95% ethanol to the supernatant to make it Its alcohol content reaches 90%, and a brown precipitate appears. After standing for 3-6 hours, the supernatant is removed to collect the precipitate, dried, and brown or dark brown viscose solid thick yam glycoprotein can be obtained.
Embodiment 2
[0015] Embodiment 2: the preparation of yam glycoprotein
[0016] Take 1000g of the original Chinese yam and crush it into a coarse powder, add 3 times the amount of water to heat, the temperature is 70°C, extract twice, each time for 3 hours, after filtering, combine the two extracts, concentrate 50%, add ethanol with a concentration of 95% Make the alcohol content reach 70% in the concentrated solution, white precipitate appears, let it stand for 3-6 hours, separate the precipitate from the supernatant, and continue to add ethanol with a concentration of 95% to the supernatant to make the alcohol content reach 90% %, a brown viscose precipitate appears, the supernatant is removed, the precipitate is collected, and vacuum-dried to obtain the purer yam glycoprotein in brown or dark brown solid.
Embodiment 3
[0017] Embodiment 3: the preparation of yam glycoprotein
[0018] Take 1000g of yam raw medicine and crush it into large particles, add 5 times the amount of water to heat, the temperature is 100°C, extract 3 times, each time for 2 hours, after filtering, combine the two extracts, concentrate to 50%, and dilute the concentration to 95% ethanol Add it to the concentrated solution to make the alcohol content reach 75%. After the white precipitate appears, extract the supernatant. Continue to add ethanol with a concentration of 98% to the supernatant to make the alcohol content reach 95%. Yellow-brown viscose appears The supernatant was removed, and the precipitate was collected for vacuum freeze-drying to obtain the purer yam glycoprotein in the form of brown crystals.
