Four new trace phenolic glycosides from Curculigo orchioides

J Asian Nat Prod Res. 2010 Jan;12(1):43-50. doi: 10.1080/10286020903427344.

Abstract

Four new trace phenolic glycosides named orcinosides D (1), E (2), F (3), and G (4) were isolated from the rhizomes of Curculigo orchioides Gaertn. Based on comprehensive spectroscopic analyses including IR, FAB-MS, HR-ESI-MS, 1D- and 2D NMR (HSQC, HMBC), their structures were elucidated as orcinol-1-O-beta-D-xylopyranoside (1), orcinol-1-O-beta-D-apiofuranosyl-(1 --> 2)-beta-D-glucopyranoside (2), orcinol-3-O-beta-D-apiofuranosyl-1-O-beta-D-glucopyranoside (3), and 1-O-beta-D-glucopyranosyl-4-ethoxyl-3-hydroxymethylphenol (4).
