preparation example 1
[0025] Take Cistanche medicinal material (dried succulent stem with scaly leaves of Cistanche diserticola Y.C.Ma), crush to 24 mesh, add 70% ethanol solution of 10 times the amount of medicinal material and extract under reflux for 2 hours, the extraction temperature is 75-80°C, and the extraction times are 3 Once, the filtrates were combined, and the filtrates were for subsequent use; the above-mentioned filtrates were concentrated under reduced pressure to no alcohol smell, and centrifuged to obtain a concentrated solution with a relative density of 1.01kg / L; the concentrated solution was placed at room temperature and passed through an ADS-17 macroporous resin column (Zhengzhou Qinshi Technology Co., Ltd.), eluted with purified water, the amount of eluent was 5 times the column volume, collected water eluate, and concentrated under reduced pressure to obtain a concentrated solution with a relative density of 1.20kg / L, that is, the active extract of Cistanche deserticola , th...

[0026] Take Cistanche medicinal material, crush it to 60 mesh, add 65% ethanol solution 20 times the amount of medicinal material, reflux and extract for 2 hours, the extraction temperature is 80-85°C, the extraction times are 4 times, the filtrate is combined, and the filtrate is set aside; the above-mentioned filtrate is concentrated under reduced pressure Centrifuge until there is no alcohol smell, and obtain a concentrated solution with a relative density of 1.02kg / L; place the concentrated solution at room temperature, pass through an AB-8 macroporous resin column (Zhengzhou Qinshi Science and Technology Co., Ltd.), and elute with purified water. The amount of dehydration is 4 times the column volume, the water eluate is collected, and concentrated under reduced pressure to a relative density of 1.23kg / L to obtain the active extract of Cistanche deserticola. The total oligosaccharide content in the extract is 39.2%, mannitol content of 25.0%, betaine content of 22.1%. Pre...

[0027] Take Cistanche medicinal material, crush it to 30 mesh, add 20 times the amount of medicinal material in 60% ethanol solution to reflux extraction for 4 hours, the extraction temperature is 85-90°C, the extraction times is 2 times, the filtrate is combined, and the filtrate is set aside; the above filtrate is concentrated under reduced pressure Centrifuge until there is no alcohol smell, and obtain a concentrated solution with a relative density of 1.03kg / L; place the concentrated solution at room temperature, pass through an ADS-17 macroporous resin column (Zhengzhou Qinshi Science and Technology Co., Ltd.), and elute with purified water. The amount of dehydration is 6 times the column volume, the water eluate is collected, concentrated under reduced pressure to a relative density of 1.25kg / L, and the active extract of Cistanche deserticola is obtained. The total oligosaccharide content in the extract is 21.1%, mannitol The content of betaine is 6.8%, and the content of...
