| Abstract: | AFM-1 and NFM-1 were obtained using CTAB-Complex, ion-exchange and gel-filtration method. It is shown that their molecular weight were 7.62×10 5 and 1.19×10 6, total sugar contents were 58.92% and 84.93% and uronic acid contents were 33.55% and 6.58%, respectively. The C, H, N contents of AFM-1 were 28.04%, 5.89%, 0.80%. The structure of both AFM-1 and NFM-1 contain pyranride and has the characteristic of glycoconjugate. |
