Abstract

Slices of berries of several varieties of Vitis vinifera were stained with HCl, vanillin-HCl or FeCl3 to demonstrate macroscopically that the bulk of the polyphenolic compounds occur in the skins, seeds and conducting tissue of grape berries at all stages of development.

Eine einfache Methode zur makroskopischen Lokalisation polyphenolischer Verbindungen in Weinbeeren

Schnitte von Beeren verschiedener Vitis vinifera-Sorten wurden mit HCl, Vanillin-HCl oder FeCl3 angefärbt, um makroskopisch zu zeigen, daß der Hauptanteil der polyphenolischen Verbindungen in allen Entwicklungsphasen in der Schale, den Samen und den Leitbündeln der Weinbeere lokalisiert ist.
