Four new stilbene dimers from the lianas of Gnetum hainanense.
Four new stilbene dimers, gnetuhainins P (1), Q (2), K (3) and L (4), were isolated from the lianas of Gnetum hainanense C. Y. Cheng. Their structures and relative configurations were determined on the basis of spectroscopic evidence, especially 2D NMR techniques.
