Embodiment 1
[0022] A preparation method of novel high-efficiency asiaticoside, comprising the following steps:
[0023] 1) Coarse 10 kg of dried centella asiatica into 50-mesh powder and put it into an extraction tank, add 100 kg of deionized water, boil at 90° C. for 2 hours, and then filter.
[0024] 2) Add 2kg of activated magnesia and 8kg of activated carbon to the filtrate, heat and stir to make them evenly dispersed in the filtrate, and observe after 1.5 hours of reaction that the liquid color disappears and becomes colorless, and the density of the filtered pressurized distillation filtrate is 1.0g / cm 3 .
[0025] 3) Adsorb the concentrated extract slowly through a D101 macroporous resin column with an aspect ratio of 2:1 to 6:1. After the adsorption is completed, wash it with deionized water, and then wash it with 50%-70% ethanol Carry out elution, and finally concentrate under reduced pressure, and dry under vacuum at 80° C. to obtain a blocky light yellow dry extract, which is ...
Embodiment 2
[0028] A preparation method of novel high-efficiency asiaticoside, comprising the following steps:
[0029] 1) Coarse 100kg of dried centella asiatica into a 50-mesh powder and put it into an extraction tank, add 1500kg of deionized water, boil at 90°C for 2 hours, and then filter.
[0030] 2) Add 30kg of activated magnesia and 100kg of activated carbon to the filtrate, heat and stir to make them evenly dispersed in the filtrate, and observe after 1.5 hours of reaction that the liquid color disappears and becomes colorless, and the density of the filtered pressurized distillation filtrate is 1.0g / cm 3 .
[0031] 3) Adsorb the concentrated extract slowly through a D101 macroporous resin column with an aspect ratio of 2:1 to 6:1. After the adsorption is completed, wash it with deionized water, and then wash it with 50%-70% ethanol Carry out elution, and finally concentrate under reduced pressure, and dry under vacuum at 80° C. to obtain a blocky light yellow dry extract, which ...
Embodiment 3
[0034] A preparation method of novel high-efficiency asiaticoside, comprising the following steps:
[0035] 1) Throw 50 kg of dried centella asiatica coarsely into 50-mesh powder and put it into an extraction tank, add 750 kg of deionized water, boil at 90° C. for 2 hours, and then filter.
[0036] 2) Add 15kg of activated magnesia and 75kg of activated carbon to the filtrate, heat and stir to make them evenly dispersed in the filtrate, and observe after 1.5 hours of reaction that the obvious liquid color disappears and becomes colorless, and the density of the filtrate by filtration and pressure distillation is 1.0g / cm 3 .
[0037] 3) Adsorb the concentrated extract slowly through a D101 macroporous resin column with an aspect ratio of 2:1 to 6:1. After the adsorption is completed, wash it with deionized water, and then wash it with 50%-70% ethanol Carry out elution, and finally concentrate under reduced pressure, and dry under vacuum at 80° C. to obtain a blocky light yello...
