摘要: Two new furostanol saponins, named chinenosides II and III, were isolated along with seven known compounds, from the bulbs of Allium chinese G. Don by a combination silica gel, Diaion HP-20, octadecylsilanized (ODS) gel column chromatographies preparative HPLC. On basis chemical spectroscopic evidence, structures III determined to be 26-O-beta-glucopyranosyl 3 beta,26-dihydroxy-(25R)-5 alpha-furost-20(22)-en-6-one 3-O-beta-xylopyranosyl-(1 --> 4)-[alpha-arbinopyranosyl(1 6) ]-beta-glucopyranoside alpha-furost-20 (22)-en-6-one 3-O-alpha-arabinopyranosyl (1 6)-beta-glucopyranoside, respectively.
