A new resveratrol trimer, vateriferol (1), having four cis-oriented methine protons and constituting four contiguous stereocenters, was isolated from the bark extract of Vateria copallifera by bioassay-guided fractionation using a combination of normal, reversed phase, and size exclusion column
Dipterocarpaceous plants contain various resveratrol oligomers that exhibit a variety of biological activities, such as antibacterial and antitumor effects. Previously, we found that vaticanol C, a resveratrol tetramer, exhibits strong cytotoxicity against various tumor cell lines. In the present
Comprehensive re-investigation of the chemical constituents in the leaves of Vateria indica (Dipterocarpaceae) resulted in the isolation of a novel resveratrol dimeric dimer having a C(2)-symmetric structure, vateriaphenol F (1), and two new O-glucosides of resveratrol oligomers, vateriosides A (2)
