Embodiment 1
[0029] Take by weighing 10kg dry Epimedium leaves, pulverize into 60 mesh powder, use 60% ethanol aqueous solution as extractant, material ratio [m (ethanol): m (Epimedium pulverized dry stem and leaf)] ratio is 10: 1, put In a microwave extractor, microwave extraction was carried out for 10 min with a power of 800W and a temperature of 50°C. The obtained extract A was vacuum concentrated to 30 L, and the obtained concentrate B was filtered through a 0.45 μm microporous membrane to obtain filtrate C. Filtrate C enters the moving separation bed, the adsorbent is polyamide, the desorbent is 50% ethanol solution, and its consumption is 3 times the volume of polyamide; the washing area is purified water; the regeneration solvent is 5% sodium hydroxide; the flow rate in the adsorption area 2BV / h; desorption zone flow rate 3BV / h; washing zone flow rate 3BV / h; regeneration zone flow rate 3BV / h; switching time 750s; Component D, concentrated and recovered ethanol, was spray-dried to ...
Embodiment 2
[0031] Take by weighing 10kg dry Epimedium leaves, pulverize through a 60 mesh sieve, use 50% ethanol aqueous solution as extractant, material ratio [m (ethanol): m (Epimedium pulverized dry stems and leaves)] ratio is 12: 1, place In a microwave extractor, microwave extraction was carried out for 10 min with a power of 800W and a temperature of 60°C. The obtained extract A was vacuum concentrated to 30 L, and the obtained concentrate B was filtered through a 0.45 μm microporous membrane to obtain filtrate C. The filtrate C enters the moving separation bed, the adsorbent is polyamide, the desorbent is 50% ethanol solution, and its consumption is 3 times the volume of polyamide; the washing area is purified water; the regeneration solvent is 5% NaOH; the flow rate of the adsorption area is 2BV / h; the flow rate in the desorption zone is 3BV / h; the flow rate in the washing zone is 3BV / h; the flow rate in the regeneration zone is 3BV / h; the switching time is 750s; the temperature...
Embodiment 3
[0033] Take by weighing 10kg dry Epimedium leaves, pulverize into 60 mesh powder, use 70% ethanol aqueous solution as extractant, material ratio [m (ethanol): m (Epimedium pulverized dry stem and leaf)] ratio is 9: 1, put In a microwave extractor, microwave extraction was carried out for 8 minutes with a power of 700W and a temperature of 50°C. The obtained extract A was vacuum concentrated to 30 L, and the obtained concentrate B was filtered through a 0.45 μm microporous membrane to obtain filtrate C. Filtrate C enters the moving separation bed, the adsorbent is polyamide, the desorbent is 50% ethanol solution, and its consumption is 3 times the volume of polyamide; the washing area is purified water; the regeneration solvent is 5% sodium hydroxide; the flow rate in the adsorption area 2BV / h; desorption zone flow rate 3BV / h; washing zone flow rate 3BV / h; regeneration zone flow rate 3BV / h; switching time 750s; Component D, concentrated and recovered ethanol, was spray-dried t...
