Y. Mimaki et al., A NEW FUROSTANOL SAPONIN WITH 6 SUGARS FROM THE BULBS OF ALLIUM SPHAEROSEPHALON STRUCTURAL ELUCIDATION BY MODERN NMR TECHNIQUES, Chemistry Letters, (6), 1996, pp. 431-432
A new bisdesmosidic furostanol saponin with six monosaccharides (1) wa
s isolated from the bulbs of Allium sphaerosephalon. The structure was
determined by the concerted use of modern NMR techniques. The corresp
onding spirostanol saponin (2) of 1 showed cytotoxic activity against
leukemia MOLT-4 cells, while 1 was inactive.
