Summary
Thin layer and high pressure liquid chromatography techniques are described for the analysis of piperine and its trans-cis isomers isopiperine, isochavicine and chavicine. U. V. irradiation of piperine produces isochavicine. Synthesis of piperine and its isomers by reacting piperidine with the corresponding acid chlorides leads to mixtures of the isomers.
Zusammenfassung
Es wird die dünnschicht-chromatographische und die Hochdruck-LLC-Analyse von Piperin sowie seinen cis-trans-Isomeren iso-Piperin, iso-Chavicin beschrieben. Durch UV-Bestrahlung entsteht aus Piperin iso-Chavicin. Bei der Synthese von Piperin und seinen Isomeren durch Umsetzung von Piperidin mit den korrespondierenden Säurechloriden entstehen Isomerengemische.
Résumé
L'analyse par chromatographie sur couche mince et par chromatographie en phase liquide sous haute pression de la pipérine et de ses isomères l'isopiperine, l'isochavicine et la chavicine est décrite. La pipérine est transformée en isochavicine par irradiation en lumière ultra-violette. La réaction de la pipéridine avec chacun des chlorures acides isomères donne un mélange d'isomères.
