Abstract
Two novel resveratrol trimers, named leachianols A (1) and B (2), were isolated from the roots of Sophora leachiana. Their structures were determined by spectroscopy using correlation spectroscopy involving long range coupling and unclear Overhauser effect experiments. The resveratrol trimers 1 and 2, which are formed by characteristics oligomerization via a pallidol (3), are the first naturally occurring oligostilbenes to be reported.
