| Popis: | The four known phenolic compounds, 3,4-dihydroxyphenethyl alcohol-6- O -caffeoyl-β- d -glucoside, acteoside (verbascoside), plantaginin and plantamajoside, and a new phenylpropanoid glycoside, hellicoside, were isolated from the aerial parts of Plantago asiatica , which is used in oriental medicine ‘Plantaginis Herba’. The structure of hellicoside was deduced from chemical and spectral evidence to be 3,4,7-trihydroxy-β-phenethyl- O -β- d -glucopyranosyl-(1 → 3)-4- O -caffeoyl-β- d -glucopyranoside. Plantamajoside and hellicoside showed high inhibition of cyclic AMP phosphodiesterase and 5-lipoxygenase. Acteoside showed high inhibition of lens aldose reductase. |
