Abstract
Two new furostanol saponins were isolated from the shoots of asparagus (Asparagus officinalis L.). One with a bitter taste was identified as 25S-furost-5-ene-3β, 22, 26-triol-3-O-(2, 4-di-α-L-rhamnopyranosyl-β-D-glucopyranoside)-26-O-β-D-glucopyranoside and the other with no bitter taste was 25S-furost-5-ene-3β, 22, 26-triol-3-O-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranoside]-26-O-β-n-glucopyranoside on the basis of spectral data and chemical and enzymatic degradation.
