Embodiment 1
[0028] The method for extracting flavonoid glycosides from Epimedium, using Epimedium as a raw material, utilizing a deep eutectic solvent, especially the solvent formed by benzyltriethylammonium chloride and polyhydric alcohols as an extractant, using water as a The diluent of the system viscosity extracts the flavonoid glycosides under the strengthening of ultrasound; and uses the collagen fiber separation material for separation and purification;
[0029] Specifically include the following steps:
[0030] 1) crush the dried Epimedium, pass through a 80-mesh sieve, add a deep eutectic solvent, then add zinc isooctanoate and zinc methacrylate, and extract under ultrasonic conditions to obtain an extract of flavonoid glycosides;
[0031] The above-mentioned deep eutectic solvent is a mixture of benzyltriethylammonium chloride, glycerin and water; the volume ratio of the three is: 1:1.2:0.8;
[0032] The preparation method of the deep eutectic solvent is: first mix and stir be...
