An investigation of the alkaloids of Lolium cuneatum

Summary In addition to three known alkaloids, the seeds ofL. cuneatum have yielded N-formylloline, N-acetylnorloline, and the new alkaloids N-methylloline and N-formylloline methiodide.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

An investigation of the alkaloids of thermopsis lanceolata

Summary The plantThermopsis lanceolata is richest in cytisine and pachycarpine at the beginning of the vegetation period, which makes it possible to obtain these substances from a single raw material simultaneously. Thermopsamine has been shown to be the optical antipode of the 13-hydroxysparteine obtained by the reduction of hydroxylupanine.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.

Berberis alkaloids. XXVI. An investigation of the alkaloids ofBerberis amurensis

In addition to alkaloids isolated previously, young shoots of Berberis amurensis Rupr. have yielded berberrubine, oxyacanthine, and pseudopalmatine, and the new amorphous base amurenine. It's structure has been established on the basis of spectral characteristics and chemical transformations.     

Berberis alkaloids. XXIX. An investigation of the alkaloids ofBerberis sibirica

The alkaloid compositions of the roots, young shoots, and leaves of Berberis sibirica have been studied, and berberine, palmatine, columbamine, berberrubine, oxyacanthine, berbamine, 8-oxoberberine, 8-oxoberrberubine, pakistanine, and pronunciferine, and also the new base N-acetylhomoveratrylamine have been isolated. This is the first time that any of these alkaloids, except berberine, have been isolated from this plant. Andizhan State Medical Institute.
