Abstract:Es werden Isolierung und Eigenschaften der Papaverrubine A und E aus Papaver rlweaa L. beschrieben. I m Hinblick auf das allgemeine chemische Verhalten und a d Grund von Untersuchungen zur Rotfiirbungsreaktion mu13 eine grode stnrkturelle iihnlichkeit dieser Stoffe mit dem aus Opium isolierten Porphyroxin bestehen.Nachdem in vorangegangenen Mitteilungen uber die Isolierung und Charakterisierung von Porphyroxin aus Opium1) und uber die Verbreitung von bisher nachgewiesenen 6 Rotfarbungsalkaloiden (Papaverrubine… Show more
“…In 1962 the empirical formula was determined by Pfeifer and Teige (6) as C Z~H~I N O~. In a series of investigations of the alkaloids of the genus Papaver, Pfeifer et al (8,9) described a total of six alkaloids which gave the characteristic red color with mineral acids. They coined the name "papaverrubines" for these compounds.…”
