摘要:
]目的:对药用植物三楞草的寡糖化学成分进行研究,以期寻找活性成分。方法:运用硅胶、ODS以及凝胶柱分离三楞草水部位,通过NMR技术鉴定其结构。结果:从三楞草水部位分离得到4个寡糖成分,分别是[O-α-D-glucopyranosyl-(1→4)]2-O-β-D-fructofuranosyl-(2→1)-α-D-glucopyranoside(1)、O-α-D-glucopyranosyl-(1→2)-O-[β-D-fructofuranosyl-(2→1)]2-α-D-glucopyranoside(2)、[O-α-D-glucopyranosyl-(1→2)]2-O-[β-D-fructofuranosyl-(2→1)]2-α-D-glucopyranoside(3)和O-α-D-glucopyranosyl-(1→2)-O-[β-D-fructofuranosyl-(2→1)]3-α-D-glucopyranoside(4)。结论:这4种寡糖成分首次从该药用植物中分离得到。
