Embodiment 1
[0064] (3β,5α,22α,25R)-spirosterine alkane-3-O-β-D-glucopyranosyl-(1→2)-O-β-D-glucopyranosyl- The preparation method of (1→4)-β-D-galactopyranoside comprises the following steps:
[0065] (1) Take 10Kg dried whole grass of Baiying, add 80L of 70% ethanol aqueous solution by volume, extract by reflux for 3 times, extract 2h each time, filter, and combine the filtrates; the above filtrate is concentrated to a relative density of 1.05 at 50°C. The extract, add 10 times the quality of the extract to disperse in distilled water, filter, take the filtrate and add it to a D151 macroporous adsorption resin column, and sequentially use 3 times the column volume of distilled water and 3 times the column volume of the 95% ethanol aqueous solution to elute , discard the eluent, and then use 4 times the column volume to elute with an ethanol aqueous solution containing a volume fraction of 6‰ hydrochloric acid. The volume concentration of ethanol in the hydrochloric acid ethanol aqueous so...
Embodiment 2
[0076] (3β,5α,22α,25R)-spirosterine alkane-3-O-β-D-glucopyranosyl-(1→2)-O-β-D-glucopyranosyl- The preparation method of (1→4)-β-D-galactopyranoside comprises the following steps:
[0077] (1) Refined total alkaloids of Baiying: take 10Kg of dried whole plant of Baiying, add 60L of 70% ethanol aqueous solution by volume, extract by reflux for 4 times, extract for 2 hours each time, filter, and combine the filtrates; the above filtrate is concentrated to 50 ℃ The extract with a relative density of 1.05 was added with distilled water of 8 times the mass of the extract to disperse, filtered, and the filtrate was added to a D151 macroporous adsorption resin column, and the volume concentration of 2 times the column volume of distilled water and 4 times the column volume was 95%. Elution with ethanol aqueous solution, discarding the eluent, and then eluting with an ethanol aqueous solution containing 6‰ hydrochloric acid with a volume concentration of 6‰, the volume concentration of e...
Embodiment 3
[0083] (3β,5α,22α,25R)-spirosterine alkane-3-O-β-D-glucopyranosyl-(1→2)-O-β-D-glucopyranosyl- The preparation method of (1→4)-β-D-galactopyranoside comprises the following steps:
[0084] (1) Refining total alkaloids of Baiying: take 10Kg dried whole plant of Baiying, add 100L of 70% ethanol aqueous solution by volume, extract twice by reflux, extract for 2 hours each time, filter, and combine the filtrates; the above filtrate is concentrated to a temperature of 50°C The extract with a relative density of 1.05 was added with distilled water of 12 times the mass of the extract to disperse it, filtered, and the filtrate was taken and added to a D151 macroporous adsorption resin column, and the volume concentration of 4 times the column volume of distilled water and 2 times the column volume was 95%. Elution with ethanol aqueous solution, discard the eluent, and then use 5 times the column volume to elute with an ethanol aqueous solution containing a volume fraction of 6‰ hydroch...
