1H and 13C NMR assignments of two new isomeric bisbenzylisoquinoline alkaloids from Cissampelos sympodialis Eichl. (Menispermaceae)

des‐7′‐O‐methylroraimine (compound 1) and epi‐des‐7′‐O‐methylroraimine (compound 2), two new isomeric bisbenzylisoquinoline alkaloids were isolated and characterized as a mixture from the rhizomes of Cissampelos sympodialis Eichl. The unambiguous structural elucidation of both isomers was performed...
