| Abstract: | Two new furostanol oligoglycosides named as aspacochioside A (1) and B (2) were isolated from the roots of Asparagus cochinchinensis (Lour.) Merr.. Their structures were elucidated to be 3-O-{a-L-rhamnopyranosyl-(14)}{b-D-glucopyranosyl}]-26-O-b-D-glucopy- ranosyl]-(25S)-5b-furostane-3b,22a,26-triol 1 and 3-O-{a-L-rhamnopyranosyl-(14)}{b-D-glu- copyranosyl}]-26-O-b-D-glucopyranosyl]-22a-methoxy-(25S)-5b-furostane-3b,26-diol 2 on the basis of spectroscopic techniques and chemical methods. |
