【 摘 要 】

To study a new protein drugs carrier, the Auricularia auricular polysaccharide (AAP) was extracted and purified from Auricularia auricular, and then characterized by the micrOTOF-Q mass spectrometer, UV/Vis spectrophotometer, moisture analyzer and SEM. The results showed that the AAP sample was water- soluble and white flocculence, its molecular weight were 20506.9 Da∼63923.7 Da, and the yield, moisture, and total sugar contents of the AAP were 4.5%, 6.2% and 90.12%(w/w), respectively. The results of the SEM revealed that the AAP dried by vacuum were spherical particles with a smooth surface, and the AAP freeze-dried had continuous porous sheet shape with the loose structure.
