Embodiment 1
[0029] The separation of saponin monomer in the Radix Ilex extract of embodiment 1
[0030] Separation of monomer components in Ilex pubescens: Take an appropriate amount of Ilex pubescens extract, dissolve and disperse it with 2-5 times the amount of water, extract with an equal volume of n-butanol three times, combine the n-butanol phases, concentrate, and obtain yellow crude total saponins. Afterwards, through macroporous resin chromatography, silica gel column layer, RP-18 reversed-phase column layer and gel column layer, separate and refine repeatedly (the specific method is recorded by the following documents: Kazuyuki Hidaka et al NewTriterpens Saponins from Ilex pubescens Chem.Pharm.Bull .35(2):524-529, 1987), to obtain monomers I, II, III and IV, respectively.
[0031] Monomer I: FAB-MS (m / z): 1351.72 (2M+Na), 1005.52 (2M-Glu+Na), 687.25 (M+Na), 663.49 (M-1); HRMS (m / z): 687.3723 (M+Na), theoretical value: 687.3720, molecular formula is C 36 h 56 o 11 . 1 H NMR (...
Embodiment 2
[0036] The preparation of embodiment 2 Ilex pubescens extract-water extraction
[0037] Take 100kg of decoction pieces of Maodongqing, add 600kg of water, heat and reflux for extraction for 3 hours, add 500kg of water for the second time, extract for 2 hours, combine the extracts, concentrate under reduced pressure to a relative density of 1.06-1.07 (70°C ± 10), pass through a container with 50kg macroporous resin aqueous chromatography column, washed with 150kg of water, then gradient eluted with 100kg of 20%, 40%, 60% and 80% ethanol solution, collected 40-60% ethanol fraction, concentrated under reduced pressure , vacuum-dried to obtain about 5kg of extract powder.
Embodiment 3
[0038] The preparation of embodiment 3 Ilex pubescens extract-alcohol extraction
[0039] Get 100kg of Herba Ilex decoction pieces, add 500kg of 50% ethanol, heat and reflux for extraction for 3 hours, extract for the second time for 2 hours, combine the extracts, concentrate under reduced pressure to a relative density of 1.06-1.07 (70°C ± 10), pass through a container 50kg macroporous resin aqueous chromatography column, washed with 100kg of water, then gradient eluted with 200kg of 40%, 60% and 80% ethanol solution, collected 40-60% ethanol fractions, concentrated under reduced pressure, vacuum Dried to obtain about 4.5kg of extract powder.
