Alkaloids ofFumaria vaillantii

FromFumaria vaillantii, collected in the Tashkent province, 18 alkaloids have been isolated of which N-methyladlumine with mp 198–199°C, []_D-45° (c 0.5; methanol) has proved to be new. Its structure has been established on the basis of spectral characteristics and a direct comparison withl-adlumine methiodide.Institute of the Chemistry of Plant Substances of the Academy of Sciences of the Uzbek SSR, Tashkent.

Alkaloids ofCorydalis stricta

The alkaloids of the epigeal part and roots ofCorydalis stricta have been studied. Of the 23 alkaloids isolated, N-methylcorypalline proved to be new, and its structure has been determined. Stilopine hydroxymethylate and pycnarrhine have been isolated from the genusCorydalis for the first time, and cheilanthiofoline isocorypalmine, scoulerine, isoboldine, reticuline, N-methylcoclaurine, coreximine, juziphine, pancorydine, corypalline, wilsonirine, stilopine, adlumidine, dihydrosanguinarine, adlumine, and bicucculine have been isolated from this species of plant for the first time.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.
