| 摘 要： | 本文应用交联明胶柱层析方法分离葛根淀粉，得到级份Ａ和级份Ｂ两组分。高碘酸氧化、蓝值及β－淀粉酶水解证明级份Ａ为支链淀粉，级份Ｂ为直链淀粉。葛根淀粉含１８．１％的直链淀粉。葛根支链淀粉平均８．６个（１→４）连接的已糖单位有一（１→６）连接的分支。

| Abstract: | Two components,A and B,by crosslinked gelatin chromatography were obtained. The results of periodate oxidation,Smith degradation.blue value and -amylolysis indicated that component A is composed of a linear chain of (1→4)linked D-glucopyranosyl residues,afid that component B is composed of (1→4) linked D-glucopyranosyl residues with (1→6) linked chain by an average of 8. 6 (1→4)linked D-glucopyranosyl residues. Amylose content of the starch from the root of Pueraria lobata is 18. 1 %. |
