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。

Abstract:

Objective: To explore the oligosaccharide constituents of Campylotropis Trigonoclada for finding bioactive natural
products. Methods: The extract water part of C. trigonoclada was chromatographied by silica gel, ODS column and LH-20 gel column
chromatography methods, and the isolates were identified based on spectroscopic analysis(1H NMR and 13C NMR). Results: Four
oligosaccharide compounds were isolated from C. trigonoclada and characterized as[O-α-D-glucopyranosyl-(1→4)]2-O- β-Dfructofuranosyl-(
2→1)-α-D-glucopyranoside(1), O-α-D-glucopyranosyl-(1→2)-O-[β-D-fructofuranosyl-(2→1)]2-α-Dglucopyranoside(
2),[O-α-D-glucopyranosyl-(1→2)]2-O-[β-D-fructofuranosyl-(2→1)]2-α-D-glucopyranoside(3)and O-α-
D-glucopyranosyl-(1→2)-O-[β-D-fructofuranosyl-(2→1)]3-α-D-glucopyranoside(4). Conclusion: Four oligosaccharide
compounds were isolated from this genus for the first time.
