Moreover, phenylalanine-derived alkaloids are also characteristic of the Nightshade plant family (Solanaceae). ), which has approximately 50 species native to Central and South America. ), with more than 1500 species distributed throughout the tropical, subtropical, and temperate zones of the globe. Certainly, the plant species belonging to the genus Solanum L.
426 Petasin, senecionine, and intergerrimine were detected. Cheng and R€ oder61 isolated two pyrrolizidine alkaloids (senkirkine and doronine) from Emilia sonchifolia. 4). Thirty genera and more than 500 species belong to this family, although new systematic research has proposed that Loganiaceae should be divided into several families. ) is especially rich in many of alkaloids such as strychnine, brucine, and curare. , which contains 190 species, more than 300 alkaloids have been isolated. 12 L-tyrosine, with its aromatic side chain, is a precursor of phenylethylamino- and isoquinoline alkaloids.
Another Aspidosperma species A. vargasii and A. 336 Jokela and Lounasmaa183 presented 1H and 13C-NMR exact spectral data for seven types of ajmaline-type alkaloids from various species of the Dogbane family. These alkaloids are as follows: ajmaline, 17-O-acetylajmaline, isoajmaline, isosandwichine, rauflorine, vincamajine, and vincamedine. 450 They are (À)-kopsinine, (À)-kopsinnic acid, (À)-kopsinoline, kopsinilam, kopsanome, (+)-5,22-dioxokopsane, eburnamenine, (+)-eburnamine, (À)-isoeburnamine, (+)-tubotaiwine, and (+)-kopsoffine.
