Isoquinoline and isoindole alkaloids from Menispermum dauricum
Copyright policy )Isoquinoline and isoindole alkaloids from Menispermum dauricum
Three isoquinoline alkaloids and an isoindole alkaloid, along with eight known compounds, were isolated from the roots of Menispermum dauricum (Menispermacese). The alkaloids were characterized as 7-hydroxy-6-methoxy-1(2H)-isoquinolinone, 6,7-dimethoxy-N-methyl-3,4-dioxo-1(2H)-isoquinolinone, 1-(4-hydroxybenzoyl)-7-hydroxy-6-methoxy-isoquinoline and 6-hydroxy-5-methoxy-N-methylphthalimide, on the basis of spectral evidence including 1D- and 2D-NMR and MS analyses.
