[0022] Example: Preparation of effective fractions of polysaccharides from bean root
[0023] a) Take 8 kg of mountain bean root decoction pieces, soak in 48 kg of water for 60 minutes, then heat and reflux for 1 hour, filter the decoction at 200 mesh, add 48 kg of water to heat and reflux and decoct for 1 hour, filter the decoction with 200 mesh, combine the two second filtrate to obtain the decoction of the root of the mountain bean;
[0024] b) At 75-80°C, decompress and concentrate the decoction of the root of the mountain bean root to a concentration of 1.5kg / L, then heat it under normal pressure at 98°C for 1.5 hours, and then cool it to room temperature to obtain the root of the mountain root water extract;
[0025] c) adding ethanol with a volume fraction of 95% to the aqueous extract of the bean root obtained in step b), stirring while adding, until the final volume fraction of ethanol is 80%, standing still, and collecting the precipitate;
[0026] d) Carry out gra...
Embodiment 1
[0031] Weigh 8 kg of shredded mountain bean root, soak it overnight with 12 times the dosage of water, heat and extract for 2 hours, pour out the water, centrifuge while it is hot (3000r / min, 10min), continue to add 10 times and 8 times the dosage of water to heat the dregs respectively Extract for 1.5h and 1h, respectively pour out the water and centrifuge while it is hot, concentrate the water in reverse gradient to 1:1 (1g of crude drug is equivalent to 1mL), add ethanol with a volume fraction of 95% to make the alcohol content reach 80%. Centrifuge after overnight, add 1:50 hot water to dissolve the precipitate and then centrifuge, add 95% ethanol to the water solution to make the alcohol content reach 80%, let stand at low temperature overnight, centrifuge, add 95% ethanol to the precipitate, stir and then centrifuge, The precipitate was vacuum-dried (40° C.), and 257.6 g of the water-extracted and alcohol-precipitated part of the root of the mountain bean root was obtaine...
