Twochromones isolated from the methanol extract of glasswort (Salicornia europaea L.) were elucidated to be 7-hydroxy-6-methoxychromoneand 7 O>-/?-D-glucopyranosyl-6-methoxychromone on the basis of chemical and spectral analyses and synthetic studies. These two are natural products hitherto unknown.In a previous paper,1} we have reported that four compounds were isolated from the reddish leaves and stems of glasswort and CompoundsI, II and III were determined to be 2'-hydroxy-6,7-methylenedioxyisoflavone, ( -)-(2S)-2' -hydroxy-6,7-methylenedioxyflavanone and 2/,7-dihydroxy-6-methoxyisoflavone, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
