NOVELTY - Icariin and saponin I and II are extracted from Epimedium by pulverizing Epimedium plant, sieving through 40 mesh screen, adding purified water with amount of 5-9 times of Epimedium plant total weight, refluxing and extracting 2 times for 2-3 hours each, filtering to obtain filtered liquid (A), adding 60-75% ethanol solution to obtained filter residue with amount of 12-16 times of Epimedium plant total weight, refluxing and extracting 2 times for 1-2 hours each, filtering to obtain filtered liquid (B), and mixing filtered liquid (A) and filtered liquid (B).    USE - Extraction of icariin and saponin I and II from Epimedium (claimed).    ADVANTAGE - Extraction method is environment-friendly and has fast absorption process, high product yield and purity, short production period, and low energy consumption.    DETAILED DESCRIPTION - Icariin and saponin I and II are extracted from Epimedium by pulverizing Epimedium plant, sieving through 40 mesh screen, adding purified water with amount of 5-9 times of Epimedium plant total weight, refluxing and extracting 2 times for 2-3 hours each, filtering to obtain filtered liquid (A), adding 60-75% ethanol solution to obtained filter residue with amount of 12-16 times of Epimedium plant total weight, refluxing and extracting 2 times for 1-2 hours each, filtering to obtain filtered liquid (B), mixing filtered liquid (A) and filtered liquid (B), suction-filtering, vacuum-concentrating to recover ethanol and obtain primary extract, extracting obtained primary extract using purified water, adjusting pH to 2-2.5, standing, filtering to obtain icariin extract, eluting icariin extract using macroporous absorption resin, washing macroporous absorption resin using ethanol solution, collecting and retaining eluent, adding medical activated carbon to eluent with amount of 0.05-0.09 times of eluent weight, refluxing for 10-19 minutes, reducing temperature to 30-40 degrees C, filtering to obtain filtered liquid (C), separating and purifying filtered liquid (C) using simulated moving bed chromatography, crystallizing, filtering to obtain icariin-rich crystal, collecting filtered liquid (D), spray-drying icariin-rich crystal to obtain pure icariin, adding Tween-80 (RTM: Polyoxyethylene (20) sorbitan monooleate) in filtered liquid (D), enzymolyzing using beta -glucosidase or cellulase, and performing separation and purification to enzymolysis liquid using D101 and A-8 mixed filled-macroporous resin chromatographic column.
