Study on Oligosaccharide Constituents of Medicinal Plants Campylotropis Trigonoclada

Abstract

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.

Key words: Campylotropis, Campylotropis Trigonoclada, chemical constituent, oligosaccharide
