Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0028] Implementation example 1:
[0029] A kind of high content stevioside A 3 The extraction method of glucoside, its steps are as follows:
[0030] 1) Water extraction step: extract 200g of crushed Stevia rebaudiana with 2000ml of drinking water at a water temperature of 80±5°C for 2-3 times, 1 hour each time, and filter.
[0031] 2) Resin separation step: put on the column, pass the filtrate through a HPD-600 type macroporous resin column, elute with 85% (mass) methanol, pass the desorption solution through an anion exchange resin column, and get the effluent part to obtain 2500ml.
[0032] 3) Decolorization step: add 25g of activated carbon, decolorize at a temperature of 80±5°C for 30 minutes, filter, and dry to obtain 5.5g of crude product.
[0033] 4) Crystallization step: 5.5 g of the crude product was dissolved with 22 ml of 70% m...
