The invention belongs to the technical field of biological
pharmacy, and particularly relates to rhizoma polygonati
polysaccharide with the effects of preventing
acute alcoholism, dispelling the effects of
alcohol and protecting the liver as well as a preparation method and application of the rhizoma polygonati
polysaccharide. The method comprises the following steps: crushing dried rhizoma polygonati in a
crusher, taking a certain amount of rhizoma polygonati
powder, adding
distilled water according to a set material-
liquid ratio, adjusting the pH value to 5.0, adding 1% of compound
enzyme, putting into a water bath kettle, carrying out ultrasonic-assisted extraction at 65 DEG C for 55 minutes, carrying out
enzyme deactivation at 95 DEG C for 10 minutes, filtering while hot, putting filtrate into a
rotary evaporator, carrying out
evaporation concentration, adding a Sevage
reagent with the volume 4 times that of the filtrate, shaking for 20 minutes, centrifuging to remove
protein, and dialyzing with deionized water for 24 hours, and adding 95%
ethanol, standing overnight, centrifuging for 15 minutes at the speed of 3500 r / min, and freeze-
drying the precipitate to obtain the
polygonatum polysaccharide.
Polygonatum sibiricum polysaccharide can effectively enhance the activity of
ethanol dehydrogenase and
acetaldehyde dehydrogenase and promote
catabolism of
alcohol.
