Abstract

The stem extract, which was shown to contain high amounts of phenolics and significant antioxidant potency, was further analysed employing liquid chromatography-electrospray ionisation mass spectrometry, in an effort to obtain a deeper insight into its polyphenolic composition. The compounds identified were mainly flavanols (a trimer and a galloylated dimer), flavonols (rutin and quercetin 3-O-glucuronide), stilbenes (trans-resveratrol and a resveratrol dehydrodimer) and a dihydroflavonol glycoside (astilbin).
