Embodiment 1

[0008] Weigh 100 kg of buckwheat bran, add 5 times the amount of water respectively, extract 3 times at 70 ° C for 2 h, combine the extracts, centrifuge to remove insolubles, and put the filtrate on a macroporous adsorption resin AB-8 column (10 × 150 cm). Elute with ionized water, then elute with 5% and 10% ethanol respectively, combine and concentrate the eluents, add 4 times of 95% ethanol while stirring, let stand for 12 hours, and obtain white crude polysaccharide precipitate after centrifugation , vacuum-dried the precipitate to obtain buckwheat polysaccharide.

Embodiment 2

[0010] Weigh 100 kg of buckwheat bran, add 15 times the amount of water respectively, extract 3 hours at 60 ° C for 3 hours, combine the extracts, centrifuge to remove insolubles, and put the filtrate on a macroporous adsorption resin AB-8 column (10 × 150 cm). Elute with ionized water, then elute with 5% and 10% ethanol respectively, combine and concentrate the eluents, add 4 times of 95% ethanol while stirring, let stand for 12 hours, and obtain white crude polysaccharide precipitate after centrifugation , vacuum-dried the precipitate to obtain buckwheat polysaccharide.

Embodiment 3

[0012] Weigh 100 kg of buckwheat bran, add 20 times the amount of water respectively, extract 4 hours at 80 ° C, extract 3 times, combine the extracts, centrifuge to remove insolubles, and put the filtrate on a macroporous adsorption resin AB-8 column (10 × 150 cm). Elute with ionized water, then elute with 5% and 10% ethanol respectively, combine and concentrate the eluents, add 4 times of 95% ethanol while stirring, let stand for 12 hours, and obtain white crude polysaccharide precipitate after centrifugation , vacuum-dried the precipitate to obtain buckwheat polysaccharide.

Abstract

The invention relates to a method for or extracting polysaccharide from buckwheat brans. The method comprises the steps of extracting the buckwheat brans for 3 times at the temperature of 50-90 DEG C by using a water solution as an extracting agent to obtain an extracting solution containing the buckwheat brans, wherein the extracting solid to liquid ratio within a range of 1 : 5-1 : 30; and the extracting time id 1-5 hours; removing undissolved substances from the extracting solution via centrifugalization; loading the filter solution on a macroporous adsorption resin (AB-8) column (10*150 cm); eluting first with ionized water, and then with 5% ethanol and 10% ethanol respectively; mixing the eluting solution; concentrating the mixed solution; adding 95% ethanol with stirring; standing for 12 hours; centrifuging to obtain a white crude polysaccharide precipitate; and vacuum drying the precipitate to obtain buckwheat polysaccharide.

Description

technical field [0001] The invention relates to a production method for extracting polysaccharides from buckwheat, in particular, the invention relates to a production process for extracting polysaccharides from buckwheat bran and using different concentrations of ethanol for step-by-step precipitation to produce buckwheat polysaccharides. Background technique [0002] In recent years, due to many factors such as the improvement of living standards, changes in diet structure, increasingly tense pace of life, and less active and more sedentary lifestyle, the incidence of cardiovascular and cerebrovascular diseases has increased rapidly, and has become the first serious threat to human health. chronic disease. Cardiovascular and cerebrovascular diseases are closely related to hyperlipidemia, and the epidemic caused by hyperlipidemia has become a powerful enemy that threatens human health. With the arrival of population aging, the proportion of hypertension and other diseases ...
