Abstract: The title compound, 6,6a,11,14-tetrahydro-8-hydroxy-9-methoxy-12H-benzo[a]-1,3-benzodioxolo[4,5-g]quinolizine, C₁₉H₁₉NO₄, a protoberberine-type alkaloid, was isolated from the roots of the plant Sinomenium acutum. Both the piperidine rings adopt half-chair conformations. The molecules exist in a dimeric form through O-HO hydrogen bonding between the hydroxy group and methoxy O atom.
