Embodiment 1
[0053] 1. Extraction of Raspberry Crude Polysaccharide
[0054] Dried raspberry frozen fruit, crushed and removed seeds, added 1-10 times of petroleum ether (boiling range 60-90°C) to degrease, added 85% ethanol at 50-70°C to reflux to remove monosaccharides and pigments, and Add 5-30 times of pure water to the filtered residue for ultrasonic extraction (power 50-70W, temperature: 50-90°C, processing time: 60min-100min), centrifuge to get the supernatant, extract the filter residue twice according to the original conditions, and combine the filtrate , concentrated under reduced pressure to 1 / 4 of the original volume, added 3 to 5 times the volume of 95% ethanol, stood at 4 degrees Celsius for 24 hours, filtered to collect the filter residue, and freeze-dried to obtain the raspberry crude polysaccharide.
[0055] 2. Separation and purification of raspberry homogeneous polysaccharide fraction
[0056] The DEAE Sepharose Fast Flow filler is used for polar separation of polysacch...
