ABSTRACT
Gnetum latifolium var. funiculare Markgr. is a medicinal plant and widely distributed in mountainous areas of Vietnam. Phytochemical investigation on the trunks of this plant afforded eight stilbene derivatives (1-8) including for new compounds (1-4). Their structures were determined based on extensive analyses of HR-ESI-MS, 1D and 2D NMR spectra. Among the isolates, compounds 1-3 showed moderate NO production inhibition in LPS-activated RAW264.7 cells with the IC50 values ranging from 46.81 to 68.10â
µM, compounds 4 and 6 showed weak effects with the IC50 values of 96.57 and 79.46â
µM, respectively, compared to that of the positive control compound, dexamethasone (IC50 14.20â
µM).
