New phenolic glycosides from the seeds of Cucurbita moschata.
Two new phenolic glycosides were isolated from the seeds of Cucurbita moschata. Their structures were elucidated as (2-hydroxy)phenylcarbinyl 5-O-benzoyl-beta-D-apiofuranosyl(1-->2)-beta-D-glucopyranoside (1) and 4-beta-D-(glucopyranosyl hydroxymethyl)phenyl 5-O-benzoyl-beta-D-apiofuranosyl(1-->2)-beta-D-glucopyranoside (2) on the basis of spectroscopic analysis and chemical evidence.
