Das Vorkommen von Glucosaminestern der Hydroxy-zimtsäuren in Gewebekulturen von Nicotiana tabacum

Abstract

Tissue cultures of Nicotiana tabacum var. “Samsun” contain an array of phenolic compounds. Beside the known glucose and quinyl esters of the hydroxycinnamic acids three hitherto unreported phenolic acid esters were isolated from tobacco tissue cultures. The analytical and spectral data presented in this paper lead to the conclusion that these compounds are glucosamine esters of p-coumaric, caffeic, and ferulic acid.
