title: Three new resveratrol oligomers from the stem bark of Vatica pauciflora.
abstract: Three new stilbene oligomers (1-3) were isolated from the stem bark of Vatica pauciflora. The structures of a resveratrol heptamer (pauciflorol D) (1), a resveratrol dimer (pauciflorol E) (2), and an indanone derivative (pauciflorol F) (3) were elucidated by means of spectroscopic data interpretation, especially HMBC and NOESY NMR experiments.
