Metabolic profiling of Vaccinium macrocarpon using 1H-NMR

Abstract

In der Naturheilkunde wird Vaccinium macrocarpon (Großfrüchtige Moosbeere, „Cranberry“, Kultur-Preiselbeere) als Mittel zur Prophylaxe und Behandlung von Harnwegsentzündungen verwendet. Klinische Studien belegen eine positive Korrelation zwischen regelmäßigem (täglichen) Konsum von Cranberrysaft und geringerer Häufigkeit von Harnwegsentzündungen. Wird der Cranberrysaft aufgrund seiner Wirkung als gesundheitsförderndes Nahrungsergänzungsmittel konsumiert, sollte eine Qualitätskontrolle der bioaktiven Inhaltsstoffe, der phenolischen Sekundärmetaboliten, erfolgen. Im Rahmen dieser Arbeit wurde mithilfe von NMR-Spektroskopie ein Profil der phenolischen Sekundärmetaboliten in einem Vaccinium-macrocarpon-Extrakt erstellt. Anschließend wurden Cranberrysäfte von vier Herstellern mittels NMR-Spektroskopie untersucht und die Daten einer Multivariaten Datenanalyse unterworfen. Die untersuchten Cranberrysäfte zeigten unterschiedliche Konzentrationen von Benzoesäure, Benzoesäure-Glucosid, Quercetin und Catechin.

In folklore and natural medicine, American cranberry is believed to be active in the prevention and treatment of urinary tract infections (UTIs). Clinical studies show a correlation of cranberry juice consumption and decreased occurrence of UTIs. Becoming important for the maintenance of human health, the quality of cranberry juice has to be monitored and assured. In the present work, a profile of the phenolic secondary metabolites of a Vaccinium macrocarpon extract, which seem to be the bioactive compounds, was established, using NMR spectrometry. Subsequently, cranberry juice samples of four different brands were analyzed by NMR in combination with multivariate data analysis. The analyzed juices showed differences depending on the manufacturer mostly by the concentrations of benzoic acid, benzoic acid glucoside, quercetin and catechin present in the juice.
