Gnetuhainin P, a new isorhapontigenin dimer, was isolated from the Lianas of Gnetum hainanense C. Y. Cheng. Its structure was established on the basis of spectroscopic evidence, especially 2D NMR techniques.
Gnetuhainin S, a new resveratrol dimer, was isolated from the lianas of Gnetum hainanense C. Y. Cheng. Its structure and relative configuration were established on the basis of spectroscopic evidence.
