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-glucopyr anosyloxy)-22-methxyfurost-5-en-3yl O-beta-D-furanosyl-(1 --> 2)-O-[6-deoxy -alpha-L-mannopyranosyl-(1 --> 4)]-beta-D-glucopyranoside. The structural i dentification was performed using detailed analysis of H-1 and C-13 NMR spe ctra including 2D NMR spectroscopic techniques (COSY, HETCOR and COLOC) and chemical conversions.
