title: Isoquinoline and isoindole alkaloids from Menispermum dauricum.
abstract: 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.
