Abstract

Two new flavonoids, pauciaurone A (1) and pauciisoflavone A (2), together with three known isoflavones (3–5), were isolated from the stems of Garcinia paucinervis. Their structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. Compounds 1 and 2 were tested for their cytotoxicities against five human tumor cell lines and showed potential cytotoxic properties against certain tumor cell lines.
