Abstract:
Very recently, we described highly antioxidative polyphenols isolated from the stem bark extract of the Garcinia buchananii tree. In this study, we describe additional antioxidants from Garcinia buchananii bark extract using hydrogen peroxide scavenging, oxygen radical absorbance capacity (ORAC), and trolox equivalent antioxidant capacity (TEAC) assays. UPLC-HR-ESI-TOF-MS(e) analysis, 1- and 2D-NMR, and circular dichroism (CD) spectroscopy led to the unequivocal identification of the antioxidati...     »
