Embodiment 1
[0016] Take 1 kg of dried flower buds of Lonicera pilosula, extract 3 times with 40% ethanol under reflux, combine the extracts, decolorize with 0.1% medicinal active carbon, filter, and after recovering ethanol, put the medicinal solution directly on the macroporous resin column, first Wash the column with water and 20% ethanol, then elute with 30%, 60%, and 90% ethanol in sequence, recover ethanol under reduced pressure, add 1% NaOH solution, degrade at 100°C for 2 hours, add 1% hydrochloric acid to adjust the pH value to 7. After letting it cool, filter the insoluble matter, dissolve it with 60% ethanol, add 5% medicinal activated carbon for decolorization, filter, recover the solvent under reduced pressure, place it, crystallize, filter, and dry to obtain Lonicera tomentosaponin Second.
Embodiment 2
[0018] 1 kg of dried flower buds of Lonicerae pilosula, reflux extraction with 80% ethanol for 3 times, combine the extracts, decolorize with 3% medicinal activated carbon, filter, recover the ethanol, put the liquid medicine directly on the macroporous resin column, and first use water and 20% ethanol to wash the column, then eluted with 30%, 60%, and 90% ethanol in turn, recovered ethanol under reduced pressure, added 5% NaOH solution, degraded at 80°C for 3 hours, added 5% sulfuric acid to adjust the pH value to 7 , let it cool, filter the insoluble matter, dissolve it with 80% methanol, add 3% medicinal activated carbon for decolorization, filter, recover the solvent under reduced pressure, place it, crystallize, filter, and dry to obtain Lonicera tomentosa saponin B .
Embodiment 3
[0020] 1 kg of dried honeysuckle flowers, reflux extraction with 90% ethanol for 3 times, combine the extracts, decolorize with 5% medicinal active carbon, filter, recover the ethanol, put the liquid medicine directly on the polyamide column, first use water and Wash the column with 20% ethanol, then elute with 30%, 60%, and 90% ethanol in turn, recover ethanol under reduced pressure, add 10% NaOH solution, degrade at 50°C for 4 hours, add 10% hydrochloric acid to adjust the pH value to 7, After letting cool, filter the insoluble matter, dissolve it with 95% ethanol, add 0.1% medicinal activated carbon for decolorization, filter, recover the solvent under reduced pressure, place, crystallize, filter, and dry to obtain Lonicera tomentosaponin B.
