About the Book

Die Alkaloidforschung in ihrem heutigen Stand stellt die großzügige Lösung eines naturwissenschaftlichen Problems dar. Ausgehend von der Arzneiwissenschaft und Pharmazie, erhielt die Alkaloidforschung aber erst Entwicklung und weiterumfassenden Inhalt durch die organische Chemie. Die vielseitige und vielgestaltige Wirkung der Pflanzenalkaloide ließ zunächst nicht den einheitlichen chemischen Aufbau dieser Körperklasse vermuten. Heute ist die chemische Systematik für die Alkaloide er- bracht, da sich diese als stickstoffhaltige Ringgebilde erwiesen haben. Nur die Zusammensetzung und die Form der einzelnen Ringe und ihre Verknüpfung miteinander bildet den wesentlichen Unterschied der einzelnen Alkaloide. Neue, bisher unbekam1te Ringsysteme wurden dabei aufgefunden, der Erkenntnis nähergebracht und in vielen Fällen durch geistvolle Forschungen der Synthese zugeführt. Die chemische Erkenntnis der Alkaloide brachte aber noch über dieses engere Thema hinaus Erfolg und wurde für das größere allgemein naturwissenschaftliche Problem, das in der Alkaloic1forschung liegt, von Bedeutung. Es erwies sich, daß zwischen elen chemischen und den botanischen Verhältnissen der Alkaloide enge Beziehungen bestehen. Die einzelnen Alkaloide einer Pflanzenfamilie sind auch in chemischer Beziehung untereinander nahe verwandt, und andererseits zeigen die Alkaloide verschiedener Pflanzenfamilien in ihrer chemischen Kon- stitution prinzipielle Verschiedenheiten. Damit war auch ohne weiteres das Verständnis für das Verhalten der verschiedenen Alkaloidpflanzen in pharmakologischer Beziehung gegeben. So ist der große naturwissenschaftliche Zusammenhang erkannt, der das Gebiet der Alkaloide in chemischer, botanischer und physio- logischer Beziehung vel, bindet und umfaßt.
