| Abstract: | Opuntia polysaccharide was extracted by hot-water digestion,and deposited by ethanol from Opuntia Milpa Alta,it was found that the best technique was 40-60 screen mesh of material partial size,extract two times,70 ℃,50 min,pH 9,ethanol concentration 95%,volume 4 times and deposit 4 hours.At last,the extract rate of Opuntia polysaccharides is 8.53%. |
