Amabiloside, a New Glycoside from Crinum amabile

Abstract
A new natural product, amabiloside (1, i.e. 3-hydroxy-4-O-β-D-glucopyranosyl-benzaldehyde) was isolated from the bulbs of Crinum amabile Donn. Its structural characterization and unequivocal 1H and 13C NMR assignments were achieved through analysis of the COSY, NOESY, HETCOR, and selective INEPT spectra. Amabiloside (1) was evaluated for its cytotoxic and antimalarial potential, but was found to be inactive. 1 was previously known only as a synthetic.
