Abstract
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 of silica gel, Diaion HP-20, and octadecylsilanized (ODS) silica gel column chromatographies and preparative HPLC. On the basis of chemical and spectroscopic evidence, the structures of chinenosides II and III were 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 and 26-O-beta-glucopyranosyl 3 beta,26-dihydroxy-(25R)-5 alpha-furost-20 (22)-en-6-one 3-O-alpha-arabinopyranosyl (1 --> 6)-beta-glucopyranoside, respectively.Entities:
