A new resveratrol trimer, vateriferol (1), having fourcis-oriented methine protons and constituting four contiguous stereocenters, was isolated from the bark extract ofVateria copalliferaby bioassay-guided fractionation using a combination of normal, reversed phase, and size exclusion column chromatography. The structure was established based on its spectroscopic data. Vateriferol (1) was evaluated in vitro for its antioxidant capacity, enzyme inhibitory activity, growth inhibitory activity on a number of cancer cell lines, neuroprotective activity, and anti-inflammatory activity. Vateriferol (1) exhibited AChE inhibitory activity (IC508.4 ± 0.2 μM), ORAC activity (2079 ± 0.20 TE/g), and neuroprotective activity at 1.5 μM using PC12 cells deprived of oxygen and glucose and lowered NO levels in lipopolysaccharide-stimulated SIM-A9 microglial cells at 14.7 and 73.6 μM. Vateriferol (1) exhibited weak cytotoxic potency (<50% growth inhibition) against the tested cell lines at 147.2 μM.
