Embodiment 1
[0024] 1 kg of Huanglaguo root powder, soaked and extracted three times with 12 times, 10 times and 8 times of 70% alcohol at 80°C, (3 hours for the first time, 2 hours for the second time, 2 hours for the third time) and filtered , merge the filtrate, reclaim the solvent or evaporate to dryness until concentrated to 1 liter, according to the macroporous adsorption resin and medicinal material amount according to the macroporous adsorption resin (HPD100) column chromatography separation in the ratio of 1: 1, adopt the gradient elution method, successively water , 40% water-containing alcohol, 70% water-containing alcohol, and 90% water-containing ethanol for elution, each gradient washes 8 retention volumes, combines the ethanol eluent, decolorizes with magnesium oxide, and adds magnesium oxide to reflux at 80 grams per liter Decolorize for 1 hour, filter, and the filtrate is concentrated under reduced pressure and dried to obtain 170 g (yield 17%) of the total saponins of the ...
Embodiment 2
[0026] 1 kg of yellow wax fruit stem powder, soaked and extracted three times with 10 times, 8 times and 6 times of 60% alcohol at 60°C, (3 hours for the first time, 2 hours for the second time, 2 hours for the third time) and filtered , combine the filtrate, reclaim the solvent or evaporate to dryness until concentrated to 1 liter, the above-mentioned total extract is extracted 3-8 times with 0.5-3 times the volume of water-saturated n-butanol according to the ratio of medicinal material: n-butanol as 1:1 , combined with n-butanol to obtain the n-butanol extract of Huanglaguo. Decolorize with magnesia, add 80 grams per liter of magnesia to reflux for decolorization for 1 hour, filter, and the filtrate is concentrated under reduced pressure and dried to obtain 182g (yield 18.2%) of the total saponins of huangcuruo. Saponins are further separated and purified by normal phase silica gel column chromatography, and eluted with different ratios of chloroform-methanol or acetone-met...
Embodiment 3
[0028] 1 kg of yellow wax fruit leaf powder, soaked and extracted three times with 8 times, 6 times and 6 times of 65% alcohol at 80°C, (3 hours for the first time, 2 hours for the second time, 2 hours for the third time) filter , merge the filtrate, reclaim the solvent or evaporate to dryness until concentrated to 1 liter, according to the macroporous adsorption resin and medicinal material amount according to the macroporous adsorption resin (HPD100) column chromatography separation in the ratio of 1: 1, adopt the gradient elution method, successively water , 40% water-containing alcohol, 70% water-containing alcohol, and 90% water-containing ethanol for elution, wash 9 retention volumes for each gradient, combine the ethanol eluents, decolorize with magnesium oxide, and add magnesium oxide to reflux at 80 grams per liter Decolorize for 1 hour, filter, and the filtrate is concentrated under reduced pressure and dried to obtain 120 g (yield 12%) of the total saponins of the fr...
