摘要： 从罂粟花粉中纯化得到由等量阿拉伯和半乳糖基组成的阿拉伯半乳聚精PS(1),经NMR和甲基化分析,证明PS(1)分子中含有β(1→3)、β(1→6)、β(1→3,6)半乳吡喃糖苷键和α(1→5)、β(1→3)阿拉伯呋喃糖苷键。在200nm处,PS(1)具有正圆二色性。

Abstract: A polysaccharide PS(1), which was purified from the pollen of papaver somniferum, is composed of arabinose and galactose residues with molar ratio of 1: 1.There are β(1→5), β(1→6), β(1→3, 6)galacpyranosyl and α(1→5), β(1→3) arabinofuranosyl residues in sugar chain, Circular dichrosim of several pollen polysaccharides have been studied.

Key words: Papaver somniferum, Pollen polysaccharides, Structure, Circular dichroism
