n-alkyl glycosides and p-hydroxybenzoyloxy glucose from fruits of Crescentia cujete

The fruits of Crescentia cujete afforded eight new compounds, along with four known compounds, acanthoside D, beta-D-glucopyransoyl benzoate, (R)-1-O-beta-D-glucopyranosy1-1,3-octanediol, and beta-D-fructofuranosyl 6-O-(p-hydroxybenzoyl)-alpha-D-glucopyranoside. The structures of the new glycosides were established as three glycosides of (2R,4S)-2,4-pentanediol, two glycosides of (R)-4-hydroxy-2-pentanone, two glycosides of(R)-1,3-octanediol and 6-O-(p-hydroybenzoyl)-D-glucose, by spectroscopic and chemical methods.
