Alkaloids ofDelphinium dictyocarpum

From the plantDelphinium dictyocarpum DC, in addition to alkaloids described previously, we have isolated N-methyllaurotetanine, isoboldine, and the new bases dictyzine, dictyonine, delectinine and delporphine. The structure of 1,2,10-trimethoxy-3,9-dihydroxy-aporphine has been established for delporphine.
