| 中文摘要: |
| 利用逆流色谱分离技术从黑木耳中分离了黑木耳多糖AAPS-3。通过完全水解、甲基化、一维和二维1H和13C 核磁共振（NMR）阐明AAPS-3的化学结构。经完全水解证实AAPS-3主要由Glc单糖组成，用HPLC方法测得其分子量为4.83×105，通过甲基化反应数据和1H和13C NMR等分析发现AAPS-3为由β-D-1,4-Glc，β-D-1,3-Glc和β-D-1,6-Glc残基构成主链的葡聚糖。 |
| 英文摘要: |
| A homogeneous polysaccharide AAPS-3 was obtained from Auricularia auricula-judae by countercurrent chromatography technology. The structure of AAPS-3 was elucidated using the method of complete acid hydrolysis, methylation, and 1D and 2D nuclear magnetic resonance (NMR). AAPS-3 was found to be mainly composed of Glc by means of total acid hydrolysis. Its molecular weight was estimated to be 4.83×105 by HPLC method. Methylation analysis and 1H and 13C NMR indicated the main chain of AAPS-3 consisted of β-D-1,4-Glc, β-D-1,3-Glc and β-D-1,6-Glc. |
