1. Alkaloids of Fumaria vaillantii and structure of norjuziphine: Continuing the separation of the combined alkaloids of Fumaria vaillantii collected in the Tashkent province during flowering and incipient budding, cheilanthifoline, parfumine, and d-stylopine (identified by comparison with authentic samples) were isolated in addition to previously mentioned alkaloids. Base (I) (C₂₀H₂₀NO₄) was identified as stylopine methohydroxide via IR, UV, NMR, and mass spectroscopy. Compound (II) from phenolic bases was characterized as a benzyltetrahydroisoquinoline alkaloid by spectral analysis; its methylation yielded an N-methyl derivative identical to juziphine, confirming (II) as norjuziphine. 2. Simplification of cyanogen bromide activation of polysaccharide supports: The cyanogen bromide method for activating polysaccharide supports for biospecific enzyme isolation is widely used but suffers from difficulties in preparing crystalline cyanogen bromide. We resolved this by using alkali metal thiocyanates instead of cyanides and directly applying the resulting cyanogen bromide solution for activation. Bromination of potassium thiocyanate produced a ~10 mM cyanogen bromide solution, which activated Sepharose gel without distillation or crystallization (though with high alkali consumption).
