Abstract

A new furostanol glycoside was isolated from the rhizomes of Costu spicatus. Its structure was established as (3 beta,22 alpha,25R)-26(beta-D-glucopyranosyloxy)-22-methxyfurost-5-en-3yl O-beta-D-furanosyl-(1 --> 2)-O-[6-deoxy-alpha-L-mannopyranosyl-(1 --> 4)]-beta-D-glucopyranoside. The structural identification was performed using detailed analysis of H-1 and C-13 NMR spectra including 2D NMR spectroscopic techniques (COSY, HETCOR and COLOC) and chemical conversions.
