Über pflanzliche Herzgifte, XXXV. Die Isolierung von zwei neuen Bufadienolid‐Glykosiden aus Bowiea volubilis Harvey

Abstract: Das durch Hochvakuumdestillation gereinigte Praparat lieB sich sowohl rnit Raney-Nickel W6 (Aufnahme 78.8% d. Th.) als auch rnit Pd/Kohle hydrieren (Aufnahme 108.1 % d. Th.). Wurde rnit Pd/Kohle bis zur Aufnahme eines Mol. Wasserstoff hydriert und an-schlieBend das vom Kontakt befreite Filtrat rnit Raney-Nickel W 6 erneut hydriert, erfolgte dariiber hinaus eine rasch abklingende weiterc Wasserstoffaufnahme von rund 0.4 Mol., die aber wohl auf eine Crackhydrierung zuriicbufiihren sein diirfte. Die Losungen ware… Show more

“…299 Katz and Tschesche et al have between them reported the presence of several bufadienolides (bovisides A 560, B, C, D, bovogenin E, bowieasubstanz G, glucobovoside A 561, nabogenin (scilliglaucosidin) 532, bovoruboside 562 and bovogenin A 563) between the years of 1950 and 1959. [300][301][302][303][304][305][306][307][308][309][310][311][312][313][314] Structures have been reported for nabogenin 532, bovoruboside 562, bovoside A 560, glucobovoside A 561 and bovogenin A 563, although the structure reported for bovoruboside is not certain. The cardioactive glycosides from B. volubilis attracted much attention in the early years of their discovery.…”

“…The same anthocyanins were produced with some small changes in the percentage composition of the different compounds. 132 The red owers of H. orientalis likewise produced a range of acylated anthocyanins (303)(304)(305)(306)(307)(308)(309)(310)(311)(312)(313)(314)(315)(316) and, as with the blue owers, the red owers produced in vitro produced the same anthocyanins with some differences in composition. [133][134][135] A later investigation of the blue owers of H. orientalis revealed a further seven anthocyanins (317)(318)(319)(320)(321)(322)(323) in addition to those isolated previously.…”
