Embodiment 1
[0017] A method for separating saponins, comprising the following steps:
[0018] A, konjac plant split fruit potato (Latin scientific name: Taccaplantaginea (Hance) Drenth) is dried and crushed, then add 9 times the amount by weight, and the volume concentration is 100% ethanol, heated and refluxed for 3 times, each extraction 2h, filter, combine the extracts, and recover the solvent by rotary evaporation to obtain the crude extract of yam;
[0019] B. According to the ratio of crude extract: purified water weight ratio of 1:10, add purified water to the crude extract to obtain a suspension mixture, then sequentially extract with petroleum ether, ethyl acetate, n-butanol, and recover the solvent by rotary evaporation , to obtain four parts extracts of petroleum ether part, ethyl acetate part, n-butanol part and water part;
[0020] C, the n-butanol part passes through the D101 macroporous adsorption resin column, the sample is dissolved and loaded with ethanol with a volume ...
Embodiment 2
[0024] A method for separating saponins, comprising the following steps:
[0025] A, konjac plant split fruit potato (Latin scientific name: Taccaplantaginea (Hance) Drenth) is dried and then pulverized, then add 10 times the amount by weight, and the volume concentration is 80% ethanol, heated and refluxed for 3 times, each extraction 2.2h, filter, combine the extracts, and recover the solvent by rotary evaporation to obtain the crude arrowroot potato extract;
[0026] B. According to the ratio of crude extract: purified water weight ratio of 1:10, add purified water to the crude extract to obtain a suspension mixture, then extract with petroleum ether, ethyl acetate, and n-butanol in sequence, and recover the solvent by rotary evaporation , to obtain four parts extracts of petroleum ether part, ethyl acetate part, n-butanol part and water part;
[0027] C, the n-butanol part passes through the D101 macroporous adsorption resin column, the sample is dissolved and loaded with...
Embodiment 3
[0031] A method for separating saponins, comprising the following steps:
[0032] A, konjac plant arrow root potato (Latin scientific name: TaccachantryeriAndre.) is dried and then pulverized, then add 11 times the amount by weight, and the ethanol with a volume concentration of 70%% is heated and refluxed to extract 3 times, each time extracting 2.3 h, filtering, combining the extracts, and recovering the solvent by rotary evaporation to obtain the crude extract of yam;
[0033] B. According to the ratio of crude extract: purified water weight ratio of 1:10, add purified water to the crude extract to obtain a suspension mixture, then extract with petroleum ether, ethyl acetate, and n-butanol in sequence, and recover the solvent by rotary evaporation , to obtain four parts extracts of petroleum ether part, ethyl acetate part, n-butanol part and water part;
[0034] C. The n-butanol part passes through the D101 macroporous adsorption resin column, the sample is dissolved and l...
