Isoquinolinium, 5,6,7-trimethoxy-1-((4-methoxyphenyl)methyl)-2-methyl-

説明This quaternary benzylisoquinoline alkaloid has been isolated from Thalictrum minus as the crystalline iodide, m.p. lSI-2°C. This salt gives an ultraviolet spectrum consisting of two absorption maxima at 265 and 31S mp.. Four methoxyl groups are present, three of these in one ring of the isoquinoline moiety.
