Polyphenolic components of extracts from the knot wood of plum “Renklod sinii” (Renclode blue)
摘要
Catechin, proanthocyanidin B-2, epiafzelechin-(4β→8)-epicatechin, dihydroquercetin, and eriodictyol were isolated via the extraction from the knot wood of plum Renclode blue (Prunus domestica “Renklod sinii”) and subsequent HPLC. Structures of these compounds were confirmed using 2D NMR spectroscopy and mass spectrometry.
