Über pflanzliche Herzgifte, XXXIII Zur Kenntnis der Bufadienolid‐Glykoside aus Bowiea Volubilis Harvey

Abstract

Aus einem in Deutschland gewachsenen Muster von Bowiea volubilis H. konnte durch Verhinderung der Selbstfermentation Gluco‐bovosid A isoliert werden. Der Zucker in den früher beschriebenen Bovotoxinen wurde als Thevetose ermittelt.

The chemistry and biological activity of the Hyacinthaceae

“…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.…”
