Embodiment 1
[0041] A preparation method for high-purity mangiferin crystals, comprising the following steps:
[0042] S1. Mangiferin extract: Take fresh mango skin and mango leaves, crush them, and use 2 times the amount of alcohol solution to ultrasonically extract twice, each time for 20 minutes; combine the extracts, filter, and concentrate under reduced pressure to obtain mangiferin extract;
[0043] S2. Crude mangiferin crystallization: extract the mangiferin extract 4 times with 1 times the amount of ethyl acetate, remove the ethyl acetate layer, then extract 4 times with 1 times the amount of mangiferin extract with petroleum ether, and remove the petroleum ether layer , to obtain the mangiferin extract after impurity removal and decolorization, place it in a constant temperature water bath at 40°C to evaporate the solvent, place it in a hot air drying oven at a constant temperature of 40°C for 24 hours, and obtain the crude mangiferin crystals;
[0044] S3. Mangiferin redissolutio...
Embodiment 2
[0047] A preparation method for high-purity mangiferin crystals, comprising the following steps:
[0048] S1. Mangiferin extract: take fresh mango skin and mango leaves, crush them, and use 4 times the amount of alcohol solution to ultrasonically extract 4 times, each time for 40 minutes; combine the extracts, filter, and concentrate under reduced pressure to obtain mangiferin extract;
[0049] S2. Crude mangiferin crystallization: extract the mangiferin extract twice with 3 times the amount of ethyl acetate, remove the ethyl acetate layer, then extract twice with 3 times the amount of mangiferin extract petroleum ether, and remove the petroleum ether layer , to obtain the mangiferin extract after impurity removal and decolorization, place it in a 70°C constant temperature water bath to evaporate the solvent, place it in a hot air drying oven at a constant temperature of 70°C for 36 hours, and obtain the crude mangiferin crystals;
[0050] S3. Mangiferin redissolution: take th...
