Abstract
Three new hydroquinone glycosides were isolated from the MeOH extract of th e aerial parts of Phagnalon rupestre. Their structures were elucidated as 1 -O-beta -glucopyranosyl-1,4-dihydroxy-2-(3 ' ,3 ' -dimethylallyl)benzene (1 ), 1-O-beta -glucopyranosyl-1,4-dihychoxy-2-(3 ' -hydroxymethyl-3 ' -methyl allyl)benzene (2), and 1-O-(4 " -O-caffeoyl)-beta -glueopyranosyl-1,4-dihyd roxy-2-(3 ' ,3 ' -dimethylallyl)benzene (3) by spectroscopic methods.
